When it’s scorching outside, you rely on your air conditioner to keep things cool inside. But is your AC taking a long time to cool down the house? This is familiar on sweltering days, which strain your cooling harder than usual. However, if it’s not especially hot outside and your cooling is still having a hard time, your HVAC system might have a problem. Try these tips to help you resolve the problem.
Dirty Air Filter
A clogged filter is the most likely reason an AC system takes too long to cool the house. The purpose of a filter is to trap airborne particles that can harm sensitive HVAC equipment. More efficient filters even trap very small airborne allergens to improve indoor air quality.
Over time, the filter becomes clogged with dust, pet hair, and textile fibers, limiting circulation. Besides making the air conditioner take a long time to cool down the house, this situation can also lead to larger energy bills, additional wear and tear, and overheating.
Solution: Check your air filter every month and exchange it if it looks dirty. Don't wait longer than three months to exchange the filter or follow the manufacturer’s recommendations. If you’re unsure where the air filter can be found, check with your HVAC technician at your next service visit.
Improper Thermostat Settings
Your thermostat needs to be compatible with your AC system to run effectively. Then, you must set it correctly to maintain a nice temperature. Installing a programmable or Wi-Fi thermostat provides the best results.
Solution: If you want to update your thermostat, require help learning about programmable settings, or don’t feel comfortable programming a thermostat on your own, call an HVAC technician at Service Experts Heating & Air Conditioning for support.
Dirty Evaporator Coil
Split-system air conditioners come with an indoor unit and an outdoor unit. The indoor unit features the evaporator coil, which absorbs heat from the air using refrigerant. It’s hard for the refrigerant to absorb heat properly if the evaporator coil is dirty, making it take longer to cool your house.
Solution: Call our HVAC professionals to clean and tune up your air conditioner. An important part of this visit consists of removing debris and grime from the evaporator coil to enhance cooling efficiency.
Dirty or Obstructed Outdoor Unit
Your AC system's cooling cycle involves moving warm refrigerant to the outdoor unit, where it exhausts heat into the outdoor air. Unfortunately, if the outdoor unit is dirty or overgrown with encroaching vegetation, the cooling process could be less effective.
Solution: Carefully clean the outdoor unit to eliminate dust, cobwebs, pine needles and grass clippings. Then, cut back bushes to at least 12 inches from the unit to increase airflow.
Refrigerant is the key to a cool home. Usually, this substance travels in a closed loop among the indoor and outdoor units. If a leak develops and your air conditioner loses refrigerant, it becomes more difficult to handle the cycle of absorbing and expelling heat from your home.
Solution: Only a licensed technician can fix refrigerant leaks and recharge the system. If you think you're dealing with this problem, get in touch with our HVAC professionals for help straight away.
Air ducts are vital to your HVAC system. A leak from either the return or supply side might make your air conditioner work harder and longer to keep your home cool.
Solution: If you notice inconsistent temperatures and excessive dust around the house, get ahold of Service Experts Heating & Air Conditioning to inspect your air ducts. Duct sealing or replacement can resolve the problem.
Dirty or Blocked Air Vents
Conditioned air can only flow around your home if the vents are open and unobstructed. Shutting too many vents can even mess with the system’s balance, resulting in more breakdowns and repair costs.
Solution: Take a look at the vents all through the house, seeing to it that they’re open and unblocked by furniture, carpeting or curtains.
Outdated or Undersized Air Conditioner
Did you install your air conditioning more than 10 to 15 years ago? As it gets older, the system becomes less effective and might be unable to maintain a comfortable home. Likewise, have you recently built a home extension or made other alterations? This could lead to an undersized air conditioner that will struggle to keep up with demand.
Solution: The only fix for an old or undersized air conditioner is to replace it. Trust our licensed HVAC technicians to size and install your new unit for comfort and efficiency.
