1. Why is my A/C running but not cooling?

If this happens, there’s a few things you can check before you call RJ Heating for a repair. First, check the batteries in your thermostat to make sure they’re working. Next, check for a tripped breaker or blown fuse. Change your air filter if it’s clogged or dirty. Finally, make sure your system is set to “cool” and that your thermostat is turned at least three degrees below your current room temperature.

2. How can I keep my home cool this summer without expensive energy bills?

No one wants to sacrifice cool comfort in the summer. Luckily, you won’t have to with these energy-efficient air conditioner tips:

  • Set your thermostat a few degrees higher than you normally would.
  • Run your ceiling fans to help circulate cool air
  • Close your blinds and shades on warm, sunny days to prevent the sun from heating your home
  • Only use major appliances during the day
  • Install a Wi-Fi thermostat to remotely adjust your home temperature to prevent unnecessary usage
  • Schedule annual A/C maintenance to keep your system running efficiently

3. Can an air conditioner really cause a summer cold?

An air conditioner cannot directly cause a cold. However, germs can thrive in any environment that’s not properly ventilated—so if your home is closed up all summer, this could trap germs inside. A sudden change between indoor and outdoor temperatures could also trigger respiratory problems in some people, too.

By properly cleaning and maintaining your air conditioner with annual maintenance, you’ll feel more comfortable and cool all summer.

4. My air conditioner is frozen—what should I do?

If your air conditioner is so cold that ice or frost forms, you should immediately turn it off to reduce the risk of serious damage. Once the ice or frost melts, try replacing the filter and restarting the unit. If ice forms again, you should call RJ Heating for air conditioner service right away. The problem could be insufficient ductwork, buildup inside the system, a broken blower, or leaking refrigerant.

5. Do I need to cover my air conditioner in winter?

Air conditioners are built to withstand the elements, so you don’t need to cover your air conditioner in the winter. We see more issues with A/Cs that have been turned on while covered and are unable to get air. Covering your air conditioner can also trap moisture inside, which can lead to rust and corrosion.

6. Can I use a window air conditioner if I don’t have central air?

Even though summer can be uncomfortable without air conditioning, we don’t recommend installing a window air conditioner if you can avoid it, for several reasons:

  • They’re inefficient and loud
  • They offer limited service
  • They pose a security risk

The perfect alternative to a window air conditioner is a ductless split system. They enable you to customize temperatures room by room. Plus, installation only requires a small, three-inch hole to connect the indoor and outdoor components.
