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

When it’s scorching outside, you count on your cooling to keep things comfortable inside. But is your AC taking a long time to cool down the house? This is familiar on sweltering days, which squeeze your cooling harder than usual. However, if it’s not very hot outside and your AC is still struggling, your HVAC system might have a problem. Follow these tips to help you troubleshoot the matter.

Dirty Air Filter

A clogged filter is the most frequent reason an air conditioning system needs more time to cool down the house. The purpose of a filter is to catch airborne debris that can damage delicate HVAC equipment. More efficient filters even trap tiny airborne contaminants to improve indoor air quality.

Over time, the filter becomes blocked up with dust, pet hair, and textile fibers, limiting airflow. Besides making an AC unit take a long time to cool down the house, this situation can also lead to more expensive energy bills, additional wear and tear, and overheating.

Solution: Check your air filter once a month and change 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 uncertain where the air filter is located, talk to a local HVAC technician at your next service appointment.

Improper Thermostat Settings

Your thermostat must be compatible with your cooling to work effectively. Then, you must set it correctly to reach a comfortable temperature. Using a programmable or Wi-Fi thermostat produces the best results.

Solution: If you want to replace your thermostat, require help learning about programmable options, or don’t feel comfortable programming a thermostat on your own, contact an HVAC technician at D.A. Bennett Service Experts for support.

Dirty Evaporator Coil

Split-system air conditioners need an indoor unit and an outdoor unit. The indoor unit features the evaporator coil, which collects heat from the air with the refrigerant. It’s challenging for the refrigerant to absorb heat properly if the evaporator coil is dirty, making it take longer 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 maintenance involves clearing away debris and grime from the evaporator coil to enhance cooling efficiency.

Dirty or Obstructed Outdoor Unit

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

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

Refrigerant Leak

Refrigerant is the key to a cool home. Usually, this substance travels in a closed loop back and forth between the indoor and outdoor units. If a leak occurs and your air conditioner loses refrigerant, it becomes less capable of absorbing and dissipating 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, call our HVAC professionals for help straight away.

Leaky Ductwork

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

Solution: If you are dealing with uneven temperatures and an excessive amount of dust inside the house, contact D.A. Bennett Service Experts to inspect your ductwork. Duct sealing or replacement can resolve the problem.

Dirty or Blocked Air Vents

Conditioned air can only flow through your home if the vents are open and free from any obstructions. Closing too many vents can even disrupt the system’s balance, leading to increased breakdowns and repair costs.

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

Aging or Undersized Air Conditioner

Did you set up your air conditioner more than 10 to 15 years ago? As time passes, the system becomes less efficient and might be unable to maintain steady cooling. Likewise, have you recently completed a home extension or made other alterations? This can result in 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. Depend on our licensed HVAC technicians to size and install your new unit for comfort and efficiency.
