When it’s sizzling outside, you depend on your AC system to keep things cool inside. But is your AC taking a long time to cool down the house? This is familiar on sweltering days, which push your AC system harder than usual. However, if it’s not particularly hot outside and your air conditioning is still struggling, your HVAC system could have a problem. Use these tips to help you troubleshoot the problem.
Dirty Air Filter
A clogged filter is the most likely reason an AC system takes too long to cool the house. The function of a filter is to trap airborne pollutants that may damage your HVAC equipment. More advanced filters even catch tiny airborne particles to enhance indoor air quality.
As time passes, the filter becomes blocked up with dust, pet hair, and textile fibers, limiting the flow of air. Besides making an air conditioning system take longer to cool down the house, this issue can also result in more expensive energy bills, increased wear and tear, and overheating.
Solution: Check your air filter every month and exchange it if it looks dirty. Don't wait over three months to replace the filter or follow the manufacturer’s recommendations. If you’re not sure where your air filter is located, ask an HVAC technician at your next service appointment.
Improper Thermostat Settings
Your thermostat needs to be compatible with your air conditioner to work correctly. Then, you must set it correctly to sustain a nice temperature. Implementing a programmable or Wi-Fi thermostat provides the best results.
Solution: If you want to update your thermostat, need help learning about programmable settings, or don’t feel comfortable programming a thermostat on your own, get in touch with an HVAC technician at Service Experts Heating & Air Conditioning for assistance.
Dirty Evaporator Coil
Split-system air conditioners need 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 dirty, making it take more time to cool your house.
Solution: Contact our HVAC experts to clean and tune up your air conditioner. Part of this call consists of clearing away dirt and grime from the evaporator coil to improve cooling efficiency.
Dirty or Obstructed Outdoor Unit
The cooling cycle involves sending heated refrigerant to the outdoor unit, where it exhausts heat away from your home. That said, if the outdoor unit is dirty or overgrown with encroaching yard waste, the cooling process can be less effective.
Solution: Carefully hose down the outdoor unit to get rid of dust, cobwebs, pine needles and grass clippings. Then, trim back bushes to around 12 inches from the unit to enhance circulation.
Refrigerant is an essential tool to effective cooling. Typically, this substance flows in a closed loop between the indoor and outdoor units. If a leak forms and your air conditioner loses refrigerant, it becomes less effective at absorbing and expelling heat from your home.
Solution: Only a qualified technician can mend refrigerant leaks and refresh the system. If you suspect this problem, get in touch with our HVAC pros for help straight away.
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 run harder and longer to keep your home cool.
Solution: If you experience inconsistent temperatures and high amounts of dust inside the house, call Service Experts Heating & Air Conditioning to take a look at your air ducts. Duct sealing or replacement can resolve the problem.
Dirty or Blocked Air Vents
Conditioned air can only flow throughout your home as long as the supply and return vents are open and unobstructed. Shutting too many vents can even throw off the system’s balance, resulting in more breakdowns and repair costs.
Solution: Take a look at the vents all through the house, making sure they’re open and unobstructed by furniture, carpets or window treatments.
Old or Inadequately Sized AC System
Did you install your air conditioner more than 10 to 15 years ago? As it ages, the AC becomes less effective and could fail to maintain comfortable temperatures. Additionally, have you recently finished a home extension or made other improvements? This may leave you with an undersized air conditioner that won't always keep up with demand.
Solution: The only solution for an aging or undersized air conditioner is to swap it out. Depend on our trained HVAC technicians to size and install your new unit for comfort and efficiency.
