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

When it’s scorching outside, you rely on your air conditioner to keep things cool inside. But is your air conditioning taking too long to cool down the house? This is familiar on sweltering days, which push your air conditioner harder than normal. However, if it’s not particularly hot outside and your AC is still struggling, your cooling equipment could have a problem. Use these tips to help you resolve the matter.

Dirty Air Filter

A clogged filter is the most frequent reason an air conditioner needs too much time to cool the house. The purpose of a filter is to capture airborne contaminants that can harm sensitive HVAC equipment. More advanced filters even capture tiny airborne particles to enhance indoor air quality.

Eventually, the filter becomes stuffed with dust, pet hair, and textile fibers, limiting airflow. Besides making your air conditioning system take a long time to cool down the house, this issue can also produce higher energy bills, increased wear and tear, and overheating.

Solution: Check your air filter each month and exchange it if it seems dirty. Don't wait over three months to replace the filter or follow the manufacturer’s recommendations. If you’re uncertain where your air filter can be found, talk to your HVAC technician at your next service appointment.

Improper Thermostat Settings

Your thermostat has to be compatible with your AC system to function effectively. Then, you need to set it correctly to reach a comfortable temperature. Using a programmable or Wi-Fi thermostat produces the best results.

Solution: If you want to update your thermostat, want help learning about programmable options, or aren't comfortable programming a thermostat yourself, call an HVAC technician at Bob Brown Service Experts for help.

Dirty Evaporator Coil

Split-system air conditioners have an indoor unit and an outdoor unit. The indoor unit features 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: Call our HVAC specialists to clean and tune up your air conditioner. An important part of this maintenance consists of cleaning out dust and grime from the evaporator coil to improve cooling efficiency.

Dirty or Obstructed Outdoor Unit

Your AC system's cooling cycle requires sending warm refrigerant to the outdoor unit, where it expels heat into the outdoor air. Unfortunately, if the outdoor unit is dirty or surrounded by encroaching vegetation, the cooling process can be less successful.

Solution: Lightly hose off the outdoor unit to remove dust, cobwebs, pine needles and grass clippings. Then, cut back bushes to around 12 inches from the unit to improve circulation.

Refrigerant Leak

Refrigerant is the key to effective cooling. Typically, this substance moves in a closed loop between the indoor and outdoor units. If a leak develops and your cooling loses refrigerant, it becomes more difficult to handle the cycle of absorbing and expelling heat from your home.

Solution: Only a trained technician can correct refrigerant leaks and replenish the system. If you suspect this problem, get in touch with our HVAC specialists for help at once.

Leaky Ductwork

Air ducts are the highways of your HVAC system. A leak on either the return or supply side can make your air conditioner perform harder and longer maintain comfortable temperatures.

Solution: If you are dealing with inconsistent temperatures and excessive dust in the house, contact Bob Brown Service Experts to examine your ductwork. Duct sealing or replacement can resolve the problem.

Dirty or Blocked Air Vents

Cool air can only circulate throughout your home when the vents are open and clear. Closing too many vents can even throw off the system’s balance, resulting in additional breakdowns and repair costs.

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

Outdated or Inadequately Sized AC System

Did you install your air conditioner more than 10 to 15 years ago? As it ages, the system becomes less efficient and may fail to maintain a comfortable home. Additionally, have you recently built a home add-on or made other changes? This could lead to an undersized air conditioner that can’t keep up with demand.

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