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 cool inside. But is your air conditioning taking forever to cool down the house? This is typical on sweltering days, which strain your cooling harder than normal. However, if it’s not very hot outside and your AC is still having a tough time, your HVAC system could have a problem. Use these tips to help you diagnose 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 job of a filter is to snare airborne contaminants that might harm sensitive HVAC equipment. More effective filters even trap very small airborne particles to enhance indoor air quality.

As time passes, the filter becomes clogged with dust, pet hair, and textile fibers, limiting the flow of air. Besides making your air conditioning system take more time to cool down the house, this issue can also lead to higher energy bills, higher wear and tear, and overheating.

Solution: Check your air filter every month and exchange it if it seems dirty. Try not to wait over three months to exchange the filter or follow the manufacturer’s recommendations. If you’re unsure where an air filter is, check with an HVAC technician at your next service visit.

Improper Thermostat Settings

Your thermostat must be compatible with your AC system to function correctly. Then, you need to set it correctly to maintain a comfortable temperature. Implementing a programmable or Wi-Fi thermostat offers 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 by yourself, get in touch with an HVAC technician at Service Experts Heating & Air Conditioning for help.

Dirty Evaporator Coil

Split-system air conditioners need an indoor unit and an outdoor unit. The indoor unit contains the evaporator coil, which takes in heat from the air via the refrigerant. It’s challenging for the refrigerant to hold onto heat effectively if the evaporator coil is dirty, making it take more time to lower the temperature of your house.

Solution: Call our HVAC specialists to clean and tune up your air conditioner. An important part of this maintenance consists of clearing away dirt and grime from the evaporator coil to enhance cooling efficiency.

Dirty or Obstructed Outdoor Unit

Your AC system's cooling cycle requires sending heated refrigerant to the outdoor unit, where it expels heat to the exterior. However, if the outdoor unit is dirty or covered with encroaching yard waste, the cooling cycle can be less efficient.

Solution: Lightly hose off the outdoor unit to get rid of dust, cobwebs, pine needles and grass clippings. Then, prune back bushes to around 12 inches from the unit to enhance circulation.

Refrigerant Leak

Refrigerant is an essential tool to air conditioning. Typically, this substance travels in a closed loop back and forth between the indoor and outdoor units. If a leak develops and your AC loses refrigerant, it becomes more difficult to handle the cycle of absorbing and releasing heat from your home.

Solution: Only a licensed technician can correct refrigerant leaks and refresh the system. If you think you're dealing with this problem, call our HVAC specialists for help straight away.

Leaky Ductwork

Air ducts are the arteries and veins of your HVAC system. A leak from either the return or supply side could make your air conditioner perform harder and longer to keep your home cool.

Solution: If you notice inconsistent temperatures and excessive dust in the house, get in touch with Service Experts Heating & Air Conditioning to inspect your air ducts. Duct sealing or replacement can resolve the problem.

Dirty or Blocked Air Vents

Cooled air can only move throughout your home when the supply and return vents are open and unobstructed. Shutting too many vents can even mess with the system’s balance, leading to more breakdowns and repair costs.

Solution: Inspect the vents in each room, seeing to it that they’re open and not blocked by furniture, carpets or window treatments.

Outdated or Inadequately Sized Air Conditioning System

Did you install your air conditioner more than 10 to 15 years ago? As it gets older, the system becomes less effective and may fail to maintain a comfortable home. Additionally, have you recently built a home add-on or made other changes? This might result in an undersized air conditioner that won't always keep up with demand.

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