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

When it’s scorching outside, you depend on your air conditioner to keep things cool inside. But is your air conditioner taking a long time to cool down the house? This is familiar on sweltering days, which squeeze your cooling harder than average. However, if it’s not especially hot outside and your AC is still having a hard time, your air conditioner may have a problem. Follow these tips to help you diagnose the matter.

Dirty Air Filter

A clogged filter is the most frequent reason an air conditioning system takes too long to lower the temperature of the house. The purpose of a filter is to capture airborne pollutants that may damage your HVAC equipment. More effective filters even capture very small airborne allergens to improve indoor air quality.

Over time, the filter becomes stuffed with dust, pet hair, and textile fibers, limiting circulation. Besides making an air conditioning system take a long time to cool down the house, this problem can also lead to larger energy bills, increased wear and tear, and overheating.

Solution: Check your air filter each month and replace it if it seems dirty. Try not to wait more than three months to exchange the filter or follow the manufacturer’s recommendations. If you’re not sure where the air filter is located, talk to your HVAC technician at your next service appointment.

Improper Thermostat Settings

Your thermostat needs to be compatible with your AC system to function effectively. Then, you must set it correctly to maintain a cozy temperature. Installing a programmable or Wi-Fi thermostat offers the best results.

Solution: If you want to update your thermostat, want help learning about programmable options, or may not feel comfortable programming a thermostat on your own, call an HVAC technician at Service Experts Heating & Air Conditioning for help.

Dirty Evaporator Coil

Split-system air conditioners come with an indoor unit and an outdoor unit. The indoor unit includes the evaporator coil, which collects heat from the air using refrigerant. It’s challenging for the refrigerant to soak up heat effectively if the evaporator coil is grimy, making it take longer to cool down the house.

Solution: Get in touch with our HVAC professionals to clean and tune up your air conditioner. An element of this call includes clearing away dust and grime from the evaporator coil to boost cooling efficiency.

Dirty or Obstructed Outdoor Unit

A cooling cycle requires sending heated 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 cycle can be less efficient.

Solution: Gently clean the outdoor unit to get rid of dust, cobwebs, pine needles and grass clippings. Then, trim back bushes to around 12 inches from the unit to boost ventilation.

Refrigerant Leak

Refrigerant is vital to air conditioning. Typically, this substance travels in a closed loop between the indoor and outdoor units. If a leak forms and your cooling loses refrigerant, it becomes more difficult to handle the cycle of absorbing and releasing heat from your home.

Solution: Only a qualified technician can correct refrigerant leaks and recharge the system. If you think you're dealing with this problem, get in touch with our HVAC experts for help at once.

Leaky Ductwork

Air ducts are the highways of your HVAC system. A leak in either the return or supply side might make your air conditioner work harder and longer to cool your home.

Solution: If you are dealing with inconsistent temperatures and an excessive amount of dust inside the house, contact Service Experts Heating & Air Conditioning to examine your ventilation. Duct sealing or replacement can resolve the problem.

Dirty or Blocked Air Vents

Cooled air can only flow throughout your home as long as the supply and return vents are open and clear. Closing too many vents can even disrupt the system’s balance, contributing to increased breakdowns and repair costs.

Solution: Check the vents in each room, making sure they’re open and unobstructed by furniture, carpeting or window treatments.

Aging or Undersized Air Conditioner

Did you install your air conditioner more than 10 to 15 years ago? As it gets older, the system becomes less efficient and can struggle to maintain a comfortable home. Additionally, have you recently finished a home extension or made other changes? This may leave you with 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. Trust our licensed HVAC technicians to size and install your new unit for comfort and efficiency.
