"After another vendor recommended major repairs to a central AC system, so I called Parker Heating and Cooling to get another quote. Although I did not ask for a diagnosis, Jeremy inspected the system and discovered an overlooked minor problem, which he took care of. His diligence and honesty saved us thousands of dollars! Jeremy was very responsive and easy to deal with and checked back to make sure the problem was resolved. These days "five stars" has diminished in meaning, but this truly was excellent service!"

"hired Chimney and Duct Experts based on their reviews on Google and Angis list to address a potential problem with a roof leak near my chimney. They quickly determined the flashing of my chimney was probably the reason for the leak, so they gave me a quote to rebuild the chimney flashing for $1300. They were able to do the work that same day, which I thought was great. However, the leak continued, so I moved on to roofers to help figure out the problem. I had 5 different roofing and repair companies come out, and each one said that the flashing on the chimney was terribly done, using a sealant instead of metal step flashing as is standard. I called back Chimney and Duct Experts and spoke with a supervisor. He agreed to come and redo the flashing, but insisted that fully rebuilding the flashing is only done when you get a new roof. Ended up being incorrectly done again, and I'll have to pay someone now to fix it correctly."

Heating and Air Conditioning questions, answered by experts

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

To lower humidity quickly, run a dehumidifier or your home's air conditioner or turn on exhaust fans to extract moisture. These methods can quickly and effectively bring your home's humidity levels to a comfortable condition. However, you should consistently practice humidity-reducing tasks to maintain proper indoor humidity levels.

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.

You reset your AC after a power outage by turning off the air conditioner from the thermostat, resetting the circuit breaker, waiting 30 minutes, turning on the AC from the thermostat, and waiting 10 minutes to see the impact. Sometimes, with a power outage, the AC needs time to reset itself, so resetting the circuit breaker alone may not do the trick. 

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs.
