He showed photos of dirty interior conditions and advised of all options to be considered to either upgrade or maintain the unit. No pressure to take all recommendations.

We feel safer and are breathing cleaner air. Definitely worth a try for HVAC needs. It's worth the money.

First off... I can't believe I didn't post a review HERE on Yelp!…read more I believe the review I wrote up only went to Google but it should post here too since many people use Yelp to help sort out companies to work with too! I've had to lean on this company a lot - so I have a lot to say, ha! Here's my review from 9 months back: I had a nightmare installation done by bad contractors causing a brand new unit to breakdown with every error in the book. Diego did an excellent job diagnosing the machine in 100+ degree weather. He was meticulous and went through every possible issue. Unfortunately the damage done caused the job to drag out but Diego continued working. I had a previous technician out from another company and even though I paid for their diagnostic service it's clear that I should've gone with Integrity Comfort Systems to begin with. I highly recommend this company. Everything is inspected and documented and then very clearly explained to me so I could understand the journey we're now on. No matter how many times I asked a question Diego took the time to break it down in ways I could understand (since I am not knowledgable in HVAC anything). No Mansplaining.. simply removing jargon and explaining step by step so anyone could follow. Seriously...Great job. My review from 5 months ago: I had ANOTHER HVAC issue but in my main house (HVAC is likely more than 20 years old) and Troy was sent out to take a look at what turned out to be a very dangerous situation. He was meticulous in documenting and clearly explained everything that was needed and why each thing was important for a SAFE operating system. I tend to only have catastrophic issues with units that either came with the house and are veeery old or something crazy like working with terrible contractors with bad installation and bad intentions causing MAJOR critical failures.... Nonetheless, Integrity worked with me providing a detailed estimate prioritizing what I could handle first. Review from the past 2 months: In addtion to those two experiences I had the pleasure of leaning on Chris for support in documenting the repair done on that AC unit damaged by the previous contractors. Chris was calm, cool, collected and incredibly thoughtful. He really worked with me to make sure we could clearly explain why certain repairs were absolutely necessary. Without Chris I would've been fully taken advantage of by those scam contractors. He didn't have to make himself that available to me but he truly went out of his way to make sure his customer was taken care of. It's very rare these days to find honest thoughtful people. When companies can get away with mistreating and scamming customers, greed seems to lead the way. Not with Integrity Comfort Systems - I mean, come on, Integrity is in the company name, and for good reason!!! And I must not forget to mention Julie. Julie handled all of my calls to the company to schedule repairs and help connect me with Chris to sort out the issues I had prior to working with them. There had been some stressful moments for me and she was always so helpful in guiding me to the right person. She always answered the phone, was always polite and easy to talk to, was loyal to the best interest of the client and I truly felt like she cared. Again RARE these days. Thank you so much, Julie! Chris, Julie and all their techs step up and really make sure the right thing is being done. I feel deeply indebted to all of them and they helped restore my faith in humanity. As a single woman on one moderate income dealing with the nightmares that come with homeownership and failing machines I really really needed this. I can't ever thank them enough and I could not recommend them more! All this from an HVAC company??? Yeah, I know... in 2026 when the world seems to be falling apart... these guys will make sure to take care of you. 5 stars isn't enough.

Got a quick appointment when I wanted it and my Tech, Edwyn, showed up right on time. Edwyn, did a great job, told me everything he was going to do and did, and gave me options for the future to help my system stay running for longer. Absolute pro! Booking him to come out for the furnace when the weather turns colder (when that ever happens). Edwyn and the team at Air Force are great. They will be my first call from here on out for HVAC needs.

But, I timed the visit, and it was a few minutes under an hour, and that included everything; the estimate and repair labor. The bill was $ 758.00 for that hour. I talked to the repairman about the cost of parts versus labor and he said they were not separated out. I talked to the business owner later on. He said that of the $758, the parts were about $80....although I found Amazon is cheaper. He did go through his costs with me, stating they were part of the job, but most had nothing to do with the repair but rather, costs of running a large corporation ......costs such as .....employee benefits ......travel time to and from the job ......office management ......payments on his fleet of trucks, my guess ......profit for the owner that the worker never receives. On the other hand, the costs of a self-employed serviceman would be parts and labor only, in his bill, usually $50-$100 an hour plus parts. So, bottom line, it was a simple job with cheap parts which I accepted ....trusting that it would require more time and cost than it actually did. My bad, I should have gotten another estimate, which means a second cost for a second estimate, but in this case I should have paid it. SINCE I KNEW THE REPAIR THAT WAS NEEDED, I SHOULD'VE BEEN ABLE TO BARGAIN A BIT LOWER WITH SUBSEQUENT CONTRACTORS... SOMETHING I WILL REMEMBER IN MY FUTURE CONTRACTED JOBS. My view, everything was legal, but the service of a large air conditioning company should be noticeably cheaper or else it offers no benefit to offset the cost. I saw no such benefit. Finally, I would encourage you to talk to the owner, he's pleasant and well spoken. He will have a lot to say.

If I could give a higher rating, I would! I recently renovated my mothers home. My husband and I worked very hard and most of the people we hired were sub par! But Scott Mumford, heating and air was absolutely the best! From the time his crew arrived at my home they were 100% professional, they came through like clockwork worked together and put a brand new system in the home. His crew was extremely polite, clean and efficient! I could go on and on and on about how amazing they are. You need to hire them to see for yourself, you will not be disappointed! read more
