When it’s hot outside, you rely on your air conditioner to keep things balmy inside. But is your air conditioner taking a long time to cool down the house? This is typical on sweltering days, which strain your air conditioner harder than normal. However, if it’s not very hot outside and your cooling is still having a tough time, your air conditioner may have a problem. Follow these tips to help you troubleshoot the issue.
Dirty Air Filter
A clogged filter is the most common reason an air conditioner takes too long to cool down the house. The function of a filter is to capture airborne pollutants that might harm your HVAC equipment. More effective filters even catch tiny airborne particles to improve indoor air quality.
Eventually, the filter becomes blocked up with dust, pet hair, and textile fibers, limiting airflow. Besides making your AC unit take longer to cool down the house, this situation can also result in higher energy bills, higher wear and tear, and overheating.
Solution: Check your air filter each month and change it if it looks dirty. Try not to wait over three months to exchange the filter or follow the manufacturer’s recommendations. If you’re not sure where an air filter is located, ask a local HVAC technician at your next service visit.
Improper Thermostat Settings
Your thermostat must be compatible with your AC system to function properly. Then, you need to set it correctly to maintain a nice 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 don’t feel comfortable programming a thermostat by yourself, call an HVAC technician at Service Experts Heating & Air Conditioning for assistance.
Dirty Evaporator Coil
Split-system air conditioners come with an indoor unit and an outdoor unit. The indoor unit houses the evaporator coil, which takes in heat from the air with the refrigerant. It’s hard for the refrigerant to hold onto heat effectively if the evaporator coil is grimy, making it take more time to cool down the house.
Solution: Call our HVAC experts to clean and tune up your air conditioner. Part of this maintenance involves clearing away dust and grime from the evaporator coil to improve cooling performance.
Dirty or Obstructed Outdoor Unit
Your AC system's cooling cycle requires sending hot refrigerant to the outdoor unit, where it expels heat into the outdoor air. That said, if the outdoor unit is dirty or covered with encroaching vegetation, the cooling process may be less effective.
Solution: Lightly clean the outdoor unit to remove dust, cobwebs, pine needles and grass clippings. Then, trim back bushes to a minimum of 12 inches from the unit to improve ventilation.
Refrigerant is the secret to air conditioning. Normally, this substance moves in a closed loop 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 expelling heat from your home.
Solution: Only a trained technician can repair refrigerant leaks and refresh the system. If you suspect this problem, get in touch with our HVAC professionals for help at once.
Air ducts are the arteries and veins of your HVAC system. A leak from either the return or supply side can make your air conditioner perform harder and longer to cool your home.
Solution: If you notice irregular temperatures and an excessive amount of dust inside the house, get ahold of Service Experts Heating & Air Conditioning to inspect your ductwork. Duct sealing or replacement can fix the problem.
Dirty or Blocked Air Vents
Cooled air can only circulate throughout your home as long as the air vents are open and free from any obstructions. Closing too many vents can even disrupt the system’s balance, contributing to increased breakdowns and repair costs.
Solution: Check the vents in every room, making sure they’re open and not blocked by furniture, carpets or window treatments.
Old or Undersized Air Conditioning System
Did you install your air conditioner more than 10 to 15 years ago? As time passes, the AC becomes less efficient and might struggle to maintain comfortable temperatures. Furthermore, have you recently finished a home extension or made other modifications? This might result in an undersized air conditioner that can’t keep up with demand.
Solution: The only solution for an aging or undersized air conditioner is to swap it out. Count on our licensed HVAC technicians to size and install your new unit for comfort and efficiency.
