Why Does the AC Take So Long to Cool Down the House?

When it’s sizzling outside, you trust your air conditioner to keep things cool inside. But is your air conditioning taking a long time to cool down the house? This is typical on sweltering days, which push your air conditioner harder than normal. However, if it’s not very hot outside and your air conditioning is still having a tough time, your air conditioner could have a problem. Follow these tips to help you diagnose the matter.

Dirty Air Filter

A clogged filter is the most frequent reason an AC system needs more time to cool down the house. The function of a filter is to trap airborne debris that can cause problems for delicate HVAC equipment. More effective filters even catch very small airborne allergens to enhance indoor air quality.

Over time, the filter becomes clogged with dust, pet hair, and textile fibers, reducing circulation. Besides making an air conditioner take longer to cool down the house, this situation can also lead to larger energy bills, higher wear and tear, and overheating.

Solution: Check your air filter once a month and exchange it if it looks dirty. Try not to wait over three months to change the filter or follow the manufacturer’s recommendations. If you’re unsure where an air filter can be found, ask a local HVAC technician at your next service visit.

Improper Thermostat Settings

Your thermostat needs to be compatible with your cooling to function properly. Then, you have to set it correctly to maintain a comfortable temperature. Employing a programmable or Wi-Fi thermostat produces the best results.

Solution: If you want to update your thermostat, require help learning about programmable features, or don’t feel comfortable programming a thermostat on your own, contact 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 contains the evaporator coil, which soaks up heat from the air with the refrigerant. It’s more difficult for the refrigerant to absorb heat properly if the evaporator coil is dirty, making it take more time to lower the temperature of your house.

Solution: Get in touch with 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 boost cooling efficiency.

Dirty or Obstructed Outdoor Unit

The cooling cycle involves transporting warm refrigerant to the outdoor unit, where it ventilates heat to the exterior. However, if the outdoor unit is dirty or surrounded by encroaching yard waste, the cooling process might be less effective.

Solution: Gently clean the outdoor unit to get rid of dust, cobwebs, pine needles and grass clippings. Then, cut back bushes to at least 12 inches from the unit to boost airflow.

Refrigerant Leak

Refrigerant is the secret to effective cooling. Typically, this substance moves in a closed loop between the indoor and outdoor units. If a leak develops and your air conditioner loses refrigerant, it becomes less effective at absorbing and releasing heat from your home.

Solution: Only a trained technician can correct refrigerant leaks and replenish the system. If you think you're dealing with this problem, call up our HVAC experts for help in no time.

Leaky Ductwork

Air ducts are the arteries and veins of your HVAC system. A leak on either the return or supply side can make your air conditioner work harder and longer to cool your home.

Solution: If you notice uneven temperatures and an excessive amount of dust throughout the house, get in touch with Service Experts Heating & Air Conditioning to examine 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 supply and return vents are open and unobstructed. Shutting too many vents can even mess with the system’s balance, leading to additional breakdowns and repair costs.

Solution: Check the vents in each room, seeing to it that they’re open and not blocked by furniture, rugs or drapes.

Aging or Undersized Air Conditioner

Did you put in your air conditioning more than 10 to 15 years ago? As it gets older, the AC becomes less efficient and might fail to maintain a comfortable home. Likewise, have you recently built a home add-on or made other alterations? This might lead to an undersized air conditioner that will struggle to keep up with demand.

Solution: The only fix for an aging or undersized air conditioner is to swap it out. Count on our qualified HVAC technicians to size and install your new unit for comfort and efficiency.
