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

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

On average, an AC unit lasts between 10 and 20 years. However, the specific lifespan depends on the type of unit, how often it's used, the local climate, and the quality of maintenance. Central AC units typically last 12 to 17 years, while window units have a shorter lifespan of 8 to 10 years. Portable AC units last about 5 to 10 years, and ductless mini-split systems can last up to 20 years. To extend the life of your AC unit, it's important to perform regular maintenance, such as replacing filters, cleaning coils, and scheduling annual professional tune-ups.

A non-maintained AC is more likely to perform poorly, increase your energy bills, and undergo more severe issues like breakage and water damage. That’s why DIY cleaning or professional maintenance is recommended annually. Otherwise, you might end up paying more in the end than you would for annual service. You can purchase cheap AC cleaning kits if you prefer going the DIY route.

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.
