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, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.

Both evaporator coils and condenser coils are recyclable and contain valuable, sellable metals such as copper and aluminum. Not only is it more earth-friendly to take them to a local metal recycling facility, but you can also trade them in for cash. Also, once the coils are removed from the system, they won’t have any traces of refrigerant, so you won’t have to arrange for recycling Freon or R-410A unless you’re disposing of the entire AC system.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.
