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

When it’s scorching outside, you depend on your AC system to keep things comfortable inside. But is your air conditioning taking too long to cool down the house? This is common on sweltering days, which squeeze your air conditioner harder than usual. However, if it’s not very hot outside and your cooling is still having a hard time, your air conditioner might have a problem. Try these tips to help you resolve the issue.

Dirty Air Filter

A clogged filter is the most common reason an air conditioner needs more time to cool the house. The function of a filter is to catch airborne particles that may damage your HVAC equipment. More efficient filters even catch very small airborne particles to increase indoor air quality.

Eventually, the filter becomes blocked up with dust, pet hair, and textile fibers, limiting airflow. Besides making the air conditioner take a long time to cool down the house, this issue can also result in larger energy bills, increased wear and tear, and overheating.

Solution: Check your air filter each month and replace it if it looks dirty. Try not to wait over three months to replace the filter or follow the manufacturer’s recommendations. If you’re uncertain where an air filter is, talk to a local HVAC technician at your next service visit.

Improper Thermostat Settings

Your thermostat has to be compatible with your cooling to run properly. Then, you must set it correctly to sustain a nice temperature. Employing a programmable or Wi-Fi thermostat provides the best results.

Solution: If you want to replace your thermostat, require help learning about programmable features, or don’t feel comfortable programming a thermostat yourself, call an HVAC technician at Strand Brothers Service Experts for support.

Dirty Evaporator Coil

Split-system air conditioners possess an indoor unit and an outdoor unit. The indoor unit contains the evaporator coil, which collects heat from the air with the refrigerant. It’s hard for the refrigerant to soak up heat effectively if the evaporator coil is filthy, making it take more time to cool down the house.

Solution: Contact our HVAC experts to clean and tune up your air conditioner. An important part of this maintenance consists of clearing away debris and grime from the evaporator coil to improve cooling performance.

Dirty or Obstructed Outdoor Unit

The cooling cycle will require moving warm refrigerant to the outdoor unit, where it exhausts heat to the exterior. However, if the outdoor unit is dirty or covered with encroaching vegetation, the cooling cycle may be less efficient.

Solution: Gently hose down the outdoor unit to eliminate dust, cobwebs, pine needles and grass clippings. Then, prune back bushes to at least 12 inches from the unit to increase airflow.

Refrigerant Leak

Refrigerant is an essential tool to air conditioning. Normally, this substance travels in a closed loop among the indoor and outdoor units. If a leak develops and your AC loses refrigerant, it becomes less capable of absorbing and releasing heat from your home.

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

Leaky Ductwork

Air ducts are vital to your HVAC system. A leak in either the return or supply side can make your air conditioner perform harder and longer to keep your home cool.

Solution: If you are dealing with inconsistent temperatures and excessive dust inside the house, contact Strand Brothers Service Experts to examine your ventilation. Duct sealing or replacement can fix the problem.

Dirty or Blocked Air Vents

Cool air can only circulate around your home as long as the air vents are open and unobstructed. Shutting too many vents can even mess with the system’s balance, leading to increased breakdowns and repair costs.

Solution: Inspect the vents in each room, ensuring they’re open and unobstructed by furniture, carpets or curtains.

Outdated or Undersized Air Conditioning System

Did you install your air conditioning more than 10 to 15 years ago? As time passes, the unit becomes less efficient and may be unable to maintain a comfortable home. Additionally, have you recently built a home add-on or made other improvements? This could leave you with an undersized air conditioner that will struggle to keep up with demand.

Solution: The only solution for an old or undersized air conditioner is to swap it out. Trust our certified HVAC technicians to size and install your new unit for comfort and efficiency.
