I have used them for the last 25 years. I have service with them twice a year, one for my heating and another time for my cooling. They have always been great, that's why I stay with them. I have a maintenance contract. It usually takes about 45 minutes to an hour. They are professional.

"I would highly recomend Precision Comfort. My furnace went down about a week ago. I conducted my own research into troubleshooting a furnace. I determined myself to be 90% sure of the issue effecting my furnace. Not having the time to repair the furnace, I researched HVAC companies. Precision Comfort reviews won, and they were dead on. Great service. Personable, competent. There was ample opportunity to gouge me, possibly make unnecessary repairs to rob me further. That DID NOT happen. Im a firefighter in Des Moines and know when a person is good.Precision Comfort is much better than good."

"We've never hired an electrician before so the price was a shock to us. Our electrician was very informative as to what he was doing and why and gave us choices before performing the work. He was clean and polite and friendly. He gave us the impression that he truly wanted our satisfaction and that he enjoyed his job."

Heating and Air Conditioning questions, answered by experts

Yes, it’s normal for an AC to drip water. In fact, it’s part of the dehumidifying process that takes place inside your AC unit as the condensation trickles down into the drain pan. However, it isn’t normal for your AC to sound like it’s running water or have large puddles around it. If that happens, you can try the solutions listed above or call an AC repair pro.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

Yes, high-efficiency models reduce environmental impact with lower energy use.
