"This was our second call to All Temp for service. Mike was our technician and he is very knowledgeable and professional. He gave some good advice on cooling our house, what to look for in the HVAC system in a new house (we are looking), and didn't try to up-sell me on things we didn't need. He was quick with his assessment and work. We'll be calling them again if we have HVAC issues."

"Buyer Be Aware: If the Person doing the work tells You that you Cannot Use Your Credit Card (if After 5:00 PM), Do NOT Listen! Pay the Following Day during Business Hrs.!! Also, when my New HVAC System was being installed 2 Days After Duct Cleaning, the HVAC Contractors called Me into the Basement and Showed Me the Inside of the Ductwork just after Opening it: Tons of Debris Remained Inside! Hopefully, if You Hire, Your Experience Will Be Better...Good Luck!"

"You absolutely need to hire these guys for whatever heating/cooling project is on your list. We had been ghosted by 4 HVAC companies in 9 months. Carlos Jr. called me at 9AM and by 4:30PM I not only did I have a working AC but I had an all new and upgraded unit. I am so impressed by their quick and QUALITY work. They were kind and understanding."

Heating and Air Conditioning questions, answered by experts

Yes, you can clean AC coils yourself. Just make sure that the power to your AC system is off before you begin. You’ll need some basic tools and supplies, including a soft brush, cloth, screwdriver, and a commercial or homemade cleaning solution. Cleaning your coils will only cost about $10.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.

You might notice that your air conditioner isn’t running as effectively as it once did. Specifically, your AC unit could take longer to cool your home, or it might struggle to remove humidity from the air. Higher utility bills and hissing sounds coming out of your AC could also indicate a leak.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air
