How Often Do Central Air Conditioners Need To Be Replaced

The central air conditioner is one of the most important things you can put in your home, especially during the summer months!

You may not think about it, but your AC unit provides much more than comfort for your house. It keeps the environment comfortable in both your home and outside space such as your yard. A broken or malfunctioning AC unit means that not only your inside spaces are uncomfortable, but also your outside areas suffer as well.

Without it, your house stays hot and could cause damage to your familys health and safety.

The hottest part of any home is the central air conditioner. When you need heat in the winter and cool air in the summer, thats when your AC comes into play. It takes time to evaporate moisture from the system and lower the temperature inside your home. So dont be afraid to wait for your AC to completely run before you use it!

Thats why its so important to know when to get your central air conditioner replaced.

The typical lifespan of an air conditioning unit is between 7 and 13 years. After this time, you may need to replace the unit because it may still work but will likely also be less efficient and easier to damage. You can calculate how often you should replace your cooling system by looking up specific numbers for your homes size and type. For example, if you live in a 6-person house, you might want to update your air conditioner every 5 years or longer. However, if you live in a larger house with many people, such as a 10-or 12-bedroom mansion, you probably dont have to worry about updating your central air anytime soon.

Learn how much your unit costs and how often it needs to be replaced.

The precise cost of replacing central air conditioning units will vary depending on whether youre talking about installation or replacement parts. While some of those costs may seem high (such as material to install inside your home), keep in mind that contractors have to factor in their overall price of materials and still end up with a higher-than-average bill for doing so.

Determine whether or not you have enough window space for a central air conditioning system.

You will need to determine if your home has sufficient window size in order to install an HVAC unit. If your windows are large and easy to access, its great to see how clean and fresh they look from inside your house! But before you book a contractor, make sure that you have the room needed to fit a central air conditioner.

Think about whether having a central air conditioning system in your home is the best solution for you.

When it comes to replacing an old central air conditioner, size matters. The larger the unit, the better it can cool your house. But dont just buy any older AC because its running poorly. Instead, consider installing a new unit that meets your specific needs and fits within your budget.

Ask yourself if a room addition is a good option.

If you havent used central air in your home before, it can be hard to tell when your AC needs to be replaced. While you may not notice any problems with its performance, an HVAC professional can easily identify whether yours is working properly or if there are issues beyond normal maintenance such as a lack of airflow.

How to Determine Indoor Air Quality

Developing an indoor air quality policy can help you identify any areas of your home that may need extra attention when it comes to cleaning and filtering what you breathe in.

First off, track how much dust is floating through your houseespecially at risk pieces of furniture like coffee tables or end-of-bed chairs. You can watch YouTube videos to see how easy it is to gather dirt from virtually anywhere your stuff sits.

Know where your chemicals are.

You may not realize it, but many compounds can be dangerous, even if you dont think of them as toxic. Perfluoroisobutane, or PFOA, for example, has been found in recent years in the blood of nearly every person in the United States. While we might not know how harmful this substance is to our health, what we do know is that it was once used by DuPont to make Teflona chemical that prevents grease from sticking. As such, it was released into the air around manufacturing plants and eventually ended up in our homes.

Keep your cleaners up to date.

You may not think of indoor air quality as you would outdoor air, but its important to keep on top of what chemicals are in your building that can potentially damage your carpet or couchesofa. Have professional cleaning agents certified by EPA tested regularly and replace them when needed.

Consider professional cleaning.

If you have pets, older children, or other people who love your home, be sure to ask them what they think about your indoor air quality (IAQ). If everyone thinks your IAQ is ruined, then it probably is! But if many of your family members want you to fix whatever issues you have, then do so.

Test your filter systems.

Your air conditioning system is responsible for filtering your homes air, so its important that it works properly. Whether you have an individual unit or a whole-house HVAC system, get in the habit of checking your filters before you start your machine. If one of your filters needs to be replaced, replace all of them! This may sound like a lot of work, but its worth it to avoid respiratory issues from inhaling too much dust or debris into your home.

Dont forget about your candles.

Candles are an easy way to add ambience and shine light in any room, but their smoke can be difficult to escape for those who live with sensitive airways. While you may think that leaving these products out will help prevent exposure, it actually increases the risk of harm by exposing your family to inhaled particles from the burning candle wax.

Think about your pets.

Before you start thinking about what quality air your home can provide, take time to consider your pets health. If you have a dog or cat, how would fresh air be good for it? Pets love interaction, while unhealthy animals suffer from stress and anxiety when they are cooped up in their rooms all day long. Ask yourself whether an indoor lifestyle is good for your furry friend and make sure to spend plenty of time with you both now that youve decided to move!

How do You Test Indoor Air Quality

Testing your indoor air quality can help you identify any sources of pollution that may exist in your home, but it can also help you understand your familys environmental conditions and make recommendations about possible improvements.

The best way to fight against pollutants is by taking action against them. That means testing your air every few months or so (or whenever you notice an odor or smell in your house), going through your cleaning products and replacing those that could cause health problems, and changing how you handle chemicals at home.

Choose the right test.

There are lots of tests you can choose from to measure your indoor air quality, but not all are equal. Just like with any other type of testing, dont just pick anything up at your local pharmacy or buy a cheap kit online. Make sure that you get a test that is accurate and will give you what you need to know.

Be sure to take the right test for your needs.

When it comes to testing indoor air quality, its important that you get the right test for your environment or issue. Some tests can be too sensitive, while others dont provide results easy to readwhich means they may not tell you anything useful. If you want a fast and effective way to see whether an area is contaminated, check its pungent gas list. That will give you a better idea of what type of test to perform to help identify any problems.

Conduct testing at the beginning of a renovation or remodel and check back after all repairs have been made.

During home renovating or building, youll likely work with many different contractors and vendors. It can be difficult to determine which items should go first, so its important to know your options for testing indoor air quality before you start your renovations. Testing allows you to compare your findings to those of others in your areais your house getting worse? Better? There are several ways to test indoor air quality and each one provides unique information about what chemicals are present.

Take additional samples if theres evidence of mold or mildew.

Thats rightyou should have multiple air samples collected whenever there is potential for mold or mildew to exist in your home. When you purchase a test kit, consider purchasing more than one box so that you can collect enough sample to accurately determine what substances are causing your smell issue.

Know what variables affect your results.

There are lots of different factors that can impact how an air quality test measures your home, so youll want to make sure you take all those into consideration before choosing a testing kit. Some tests run more frequently than others, for example, while some include data about your heating ventilator system or plumbing systems.

Understand how results vary among testers.

Every persons individual experience with air quality is different, so what works for one may not work for you or someone else. While there are guidelines regarding indoor air quality, there arent any laws regulating it like there are regulations surrounding outdoor air quality. This means your experiences testing both types of air will differ depending on factors such as your age, sex, height, and weight.

How to Improve Indoor Air Quality in Winter

Develop a plan for heating with air conditioning.

When you turn on your heater, what kind of heat do you get? If you have warm or cool air conditions, chances are that its not very cold in your home, which means theres probably also some hot air. While using an air conditioner is one way to reduce indoor air pollution, if you have no choice but to heat your house, try to minimize the time you spend without ventilationespecially when kids and pets are involved. The more time you can allow between ventilations, the better; as soon as possible after letting hot air build up inside plans activities that will avoid contact with particles.

Take advantage of sunlight during the winter months.

Our bodies naturally crave vitamin D when were not outdoors, so when its cold and dark outside, our brains send messages that cause us to stay inside and sleep. This makes sense when you consider what happens every year around this timeseasonal allergy attacks strike millions of people as they spend more time indoors. When you open your windows, let in some sunshine, and reset your mind and body with an indoor sun ritual, you can improve your quality of life and feel better nearly anytime anywhere.

Boost your energy savings by using lights that mimic daylight.

When you turn off incandescent bulbs, youre not saving electricityyoure just going back to what light sources used to be before compact fluorescent lamps were mainstreamed into homes in the 2000s. While CFLs can have shorter lives than incandescents, they generally last at least ten years, which is much longer than most people keep their homes for. Instead of changing out all your light fixtures, try looking for LED replacements. Not only do these products look better, they also consume up to 90 percent less energy per lamp compared to traditional lighting.

Pick products that use less power.

Many energy bills come during winter because of how we heat our homes. If youre looking for a way to reduce your own energy usage, consider furnaces, air conditioning units and heaters when choosing items for your home.

Install a ventilator or heater.

If you have an air conditioner, it should be running most of the time when youre inside. One possible solution is to install a portable ventilation system, which will pull fresh air into your home through vents placed outside his wall. Or if you live in a particularly cold house, consider using a heating humidifier instead, which works by bringing indoor moisture back up to room temperature.

Dont let the moisture from cooking and bathing build up.

Probably one of the biggest challenges for improving indoor air quality is removing the accumulated natural oils that are present in our skin and hair during winters colder months. One of the best ways to do this is by taking a shower at least once every couple of days, as well as any major staining or body odor issues.

Clean your vents and radiator fans regularly.

If you have pets, its especially important to check those heaters and air filters before you leave for work or go to bed. The dry winter air can cause your heating system to wear out faster than usual, so take advantage of that fact and run your ventilators overnight to make sure theyre working properly.

How to Improve Indoor Air Quality in Office

Clean your office regularly.

Dons & Joannes Rule: You should clean by yourself each time you move something from one room to another, but we also recommend cleaning up after yourselves! If theres anything dirty or broken around your home that needs to be cleaned, you want to make sure it gets done right? So grab a basket and collect all of the trashincluding scraps of paper, straws, pieces of foodand take it wherever you usually throw out garbage. In addition to keeping your space looking nice, this will help break down all those whiteboards, carpeting and wood floors over time so your space feels more like home.

Remove dust and debris from surfaces.

Dust furniture and other objects with a microfiber cloth at least once a week.

Dusting rooms gets your property sparkling faster than any vacuum cleaner can, while also removing items that easily accumulate outside of your homedust from books or papers, hair products or even candy wrappers. Cleaning comes first prevents dust from gathering elsewhere in your office (and in much higher quantities) as well as keeps you and your coworkers happy!

Sweep or vacuum your floor.

Dusting, vacuuming, and sweeping remove dust that can otherwise become airborne and pollute the air you breathe. Regularly sweep or vacuum your office and other frequently trafficked areas with a soft-bristled broom to eliminate potential dirt traps.

Replace old wallpaper with fresh paint.

Old wallpapers featured in your office can cause indoor air pollution, which can decrease productivity and encourage health issues. If youre still using a background color or image on your walls, now is a great time to update it with a new piece that inspires you and matches your other furniture. Your more spacious offices may even inspire you to get creative and decorate yourself!

Purchase an air purifier.

When youre working inside all day, it can be hard to think of anything other than getting out into the fresh air. But those with allergies or asthma should consider an indoor air purifier, as these machines can remove allergens from the air that causes your symptoms.

Open windows for some fresh air.

Sometimes you need more than just an open dooryou need outdoor air too. When its close at hand, even feeling a little bit stale or smelly, your indoor environment can seem pretty stuffy. But making sure you have plenty of window openings lets in some cleaner air from outside. According to the American Lung Association, office buildings with doorman facilities are the best opportunity for workers to improve their indoor air quality.

How do You Test Indoor Air Quality

Testing your indoor air quality can help you identify any sources of pollution and adjust your plans to minimize risk if there's something in your home that needs fixing.

If there's an issue with your heating system, for example a leaky water heater, you may be exposed to dangerous chemicals or combustion byproducts. If your office space is large enough to accommodate all members of your team, then consider splitting it into separate areas according to gender so each person can avoid inhaling one another's fumes.

There are many ways to test your indoor air quality, but here's what one option is:

This is called an IAQ scan. A professional engineer can perform this scan or anyone with some knowledge of their equipment and software can. To conduct an IAQ scan, you'll need the right tools specifically a high-quality thermal imager for detecting heat sources inside your home and a thermometer capable of measuring temperature at various heights in your house.

Choose a testing kit.

There are many types of test kits for indoor air quality, so choose what's best for you and your family. Kits vary in how easily they can be completed and interpreted as well as their accuracy, so take into consideration any factors that influence your choice.

Follow the instructions for your testing kit.

Before you start your indoor air quality test, make sure to read all of the included materials. These include directions about how to prepare your home for the audit and what items to collect and analyze, as well as guidelines to help you determine which pollutants matter most to your health. If youre planning to take an official survey, be sure to also look at any questionnaires that were provided by your testing lab.

Have someone with you in your home.

Its best to have another person with you when testing indoor air quality. This can be a friend, family member or even your dog. Having a pal along helps ensure that you get accurate results and will help reassure any concerns you may have about what you find during your inspection.

Stay calm.

If you feel anxious, speak to your doctor before taking any test that requires you to sit still. This is especially important if you have an undiagnosed medical condition that could make you feel nervous or ill.

Breathe easy.

Your indoor air quality (IAQ) is important, whether you're testing it yourself or have a professional perform an assessment. If your space isn't properly ventilated, you run the risk of breathing in potentially hazardous compounds that can damage your lungs and organs.

How To Give Your Furnace A Tune Up

The air conditioning in your home will also be affected by the weather, especially if you live in a hot climate.

This is why we always recommend having both a heating and cooling system checked out at the same time. When you visit your local furnace repair company, let them know what temperature you want to maintain in your house. Theyll make sure that not only does their expert technician turn up the heat when needed, but also lowers it when it means protecting your possessions from excessive damage.

While a professional tune-up is definitely recommended after six months of not getting service, giving your furnace a basic cleaning every year can help extend its life.

Be sure to have all your equipment and supplies ready before you start cleaning or repairing your furnace.

Before you begin working on your heating system, have everything laid out in one place. You may find it helpful to bring small items to your local church where theyre kept or store them in another accessible location.

Have a professional mechanic clean and adjust your engine before starting work on it.

The heaters in your furnace can easily get dirty, clogged with dust, which prevents them from getting good air flowand thats bad for your system. Having an expert check out your car first is like giving it a tune up before putting it into production. They also have tools to make sure everything is running smoothly and safely.

Only a qualified technician should be allowed to do anything with your mechanical furnace.

While its great that you know how to turn the dial, have some compassion for people who dont feel comfortable reading manuals. If you can figure out what direction your microwave is going, then youre more than capable of giving your thermostat a little boost when needed. Call a friend or family member to help you if you end up with a bad day and need someone to take you through the steps.

Regardless of how much experience you may have, you could cause serious damage to your machine.

Thats righteven if you work in an office and know exactly what to do when you hear that refrigerator beep up at night, its important to let your HVAC technician guide you through this process. What sounds like simple advice can actually result in something very dangerous for your family. Let someone with expertise handle it so you dont risk damaging your furnace.

Never let children play inside the space where your furnace operates.

When youre having a hard time keeping the temperature high in your home, it can be tempting to leave your kids to run around outside when they should be staying indoors. However, playing near your heating unit exposes them to heat hazards that could cause injury or even death. For this reason alone, you want to make sure they dont venture anywhere near it.

How to Measure Indoor Air Quality

Developing an indoor air quality plan can help you understand your needs and find solutions that will work for your home.

Want to know what questions to ask your architect or designer about possible remodels? Ask them how theyll address issues like humidity, noise, and ventilation. You also should talk to your builders or real estate agents about what considerations need to be made when selling your houseor moved out of it.

Determine your specific problems.

Have you noticed changes in the quality of air inside your home? Maybe theres more dust or other particles floating around, obscuring the natural airflow patterns that normally help us breathe easier. These unwanted particulates can be caused by many sourcesdust from construction, pet hair, dryer vents, etc.and impact everyones indoor air quality differently. It may cause allergies or respiratory issues for some, while others wont notice any difference. To determine if your home has poor indoor air quality, look for signs that you experience regularly with your family (breathing trouble, skin rashes, headaches), as well as physical symptoms like coughing and asthma attacks.

Look at where your kids play, your pets sleep, and any activities or practices that cause your family members to cough or have breathing difficulties.

When youre looking around your home for signs of bad air, consider what is in the room with the most indoor air quality issues. This may be a kitchen or bathroom, but it could also be a bedroom or sitting area. If these are rooms your children spend time in, like their bunk bed or favorite playroom, they likely contribute to poor air quality there.

Think about your lifestyle.

Before you start measuring air quality, think about your daily habits and what affects your breathing pattern. This awareness can help you better understand why an indoor environment mattersand how it can be improved.

Identify your environmental concerns.

What kind of air quality issue are you concerned about? The most common indoor pollution sources are household products, including dryer sheets, fabric softeners or detergents, paint fumes, perfumes, chemicals from plants like lavender and lemon grass, etc.

Explore ways to improve ventilation and air quality.

When youre looking to measure indoor air quality, one of the first things you should consider is how to improve ventilation and airflow. Without adequate circulation of outdoor air, your office or home can quickly become too hot and stuffy, leading to headaches and discomfort.

Dont forget about your appliances.

Your refrigerator, stove, air conditionerand all those other gizmos you have in your home or officecontain chemicals that emit certain gases as they break down. These fumes can negatively affect your health and the quality of your food if its not stored properly. According to the Environmental Protection Agency (EPA), common household products such as personal computers and television sets contribute to poor indoor air quality. To avoid inhaling harmful compounds from your electronics and furniture, make sure to take everything out of useable condition before moving items into storage.

How To Do A Furnace Tune Up

Doing a furnace tune up every year is important, but it can also be beneficial to do them more often.

Most experts recommend doing at least a basic furnace cleaning every other year. But given that heating bills have been decreasing over the past few years as energy efficiency has become even more of a priority for most home owners, you may want to schedule a professional tuneup every couple of years instead of just once a year.

Have your air conditioner and heat repaired as needed.

One of the easiest ways to get an annual heating tune up is to have some repairs done to your heating system. If you havent had any issues with your furnace or AC unit in the past, its definitely worth having these things looked at by a professional.

Check your thermostat.

In order to get the most out of your heating season, its important for you to make sure that your furnace is running at its peak efficiency. That means taking time to adjust your homes climate control systemnot just your heater or air conditioner, but all systems are best when they work in balance. On especially cold days, make sure that your hot water tank isnt empty; if its too low, you could have some very uncomfortable showers!

Make sure all your furnaces are functioning properly.

The best way to ensure that your furnace is working efficiently? Visit our website, choose your product, and take a look at how we monitor energy usage in your home. If you want proof that your furnace needs maintenance, just turn on your heater for an houror even less if its close to freezing outside! That should help you determine whether or not its parts need to be replaced.

Clean out your vents and registers.

If you have air conditioners in your home, they likely need to be cleaned as well! Vent cleaning is especially important for heating systems. Without proper ventilation, your furnace will work harder causing higher bills and decreased efficiency.

Replace or repair any worn-out parts.

That old furnace might run fine, but if youre finding that it starts to leak gas every time it heats up, then its days are definitely numbered. You can replace your old heating equipment with a new system at least once, maybe even twice during your life, so dont avoid doing a basic maintenance tuneup just because your furnace is older than you are.

Run a full load of your hot water heater.

Setting aside time to perform what may be one of your simplest tasks can help ensure that you dont rush into more complicated things, like writing an entire paragraph. When considering a tune up for your furnace, it makes sense to start with something simplelike running a full load of your hot water heater or shower heads. Getting all your fixtures (fixtures are components of your plumbing system) turned on is important, but consider how much money youve spent trying to get that single load circulating in your house. Better to spend that time doing something else that will actually increase your cash flow.

How to Test Indoor Air Quality

An air quality test can reveal information about the levels of mold, pollen, and other potential pollutants that you may not be aware of.

When youre looking for an indoor testing venue, make sure to ask about available options for air samples, as well as guidelines for collection and analysis.

Such tests can also help you identify any sources of irritation or contamination in your home.

If you have allergies, theres a good chance your house is full of things that could trigger respiratory congestion and redness in your eyes or ears. A test will let you know what causes these symptoms and allow you to make recommendations about cleaning agents and materials that cause problems for you.

Conduct an inspection of your home.

Before you can correct any potential air pollution sources in your home, youll need to identify them. This means walking through your house taking note of anything that might be causing problems for your indoor air quality or could potentially be improved.

Take note of areas with a lot of mold.

If you see signs of growing mold in your home, thats one very obvious indicator that your air is probably polluted., Although it can be hard to determine if any visible mold stains your carpet or walls, small amounts of black mold growth can often appear like dirt on your window glass. While not necessarily an indication of damage itself, dirty windows are another sign to look for when checking indoor air quality.

Check for signs of fire damage.

If your home has smells that smell like smoke, you may have a fire burning somewhere in your house. You may also see dark spots on your ceilings or walls that are black from soot or ash, even if theres no sign of heat damage! Contact an environmental specialist to test your air quality and make sure theres no danger of wildfire.

Ask anyone you know has issues with respiratory problems or allergies to think about getting tested as well.

Its important to get your air quality measured, especially if you live with an allergy that makes you break out in hives or suffer other symptoms every time you breathe. If you notice a correlation between how often you sneeze or have headaches and the levels of certain toxins in your home, ask your doctor about having your air samples analyzed by a professional certified lab analyst.

Know your air quality index.

Searching for an indoor air purifier is like searching for a new pair of glasses youll definitely find a few brands that are well-known and reputable, but its also important to ensure that you purchase a device that meets or exceeds federal standards. While there may not be strict requirements under the law regarding which type of air filter your business uses, its essential to invest in a unit that filters out allergens and removes chemicals such as mold, dust, cigarette smoke and more.
