I'm glad I did. They responded in less than an hour, and a half-hour after that, the air conditioning was working again. The charge was very reasonable, and I was advised on steps to take to avoid problems in the future. I've since signed onto a service agreement to have Advanced Air Services provide regular maintenance for my HVAC system.

I just want to express how grateful I am that my warranty company sent out Kevin last week. I had…read morethe previous company that had been out several times in the last 2 years. After only a week after they were last out, they sent me Kevin. What an amazing job going through a fine tooth comb to determine what exactly was wrong. After learning the 27 year old HVAC has lived its life, I didn't hesitate to order a whole new system to replace it. Not only was Kevin early for the service calls, him and his assistant worked so incredibly fast and organized. It took no time at all for the installation of it. Even in the pouring rain. I highly recommend Kevin's Precision HVAC for any all all my needs for all 3 of our properties in the future. Thanks so much for everything you've done.

With a snow storm only a few hours away, our HVAC system stopped working. Asking the community for…read morerecommendations, Kevin messaged me to tell me he had a tech (Clayton) that would be able to swing by to look at our issue. Clayton arrived, and was able to determine we needed a part. He was able to give a "hack" to get heat until the part could be obtained the next day. Snow storm day, Kevin arrived with the part - of course our luck (we should come with a warning label) - the part is only part of the issue. Kevin was at our house for several hours talking to the manufacturer of our system trying to diagnose the issue. After determining we needed other parts, Kevin gave us other options for us to consider. Truly professional, trustworthy, hard working - in an emergency we appreciated the hard work! (Even when our "simple issue" wasn't so simple. (THIS is not an issue with the workmanship of Kevin or Clayton - it is our system - and our luck!). We truly appreciate the hard work and service they are providing for us during a snow storm. Thank you Kevin and Clayton!

We got several estimates for replacing our furnace and a/c. This was the one company I didn't feel like I was dealing with used car sales men who were trying to rip me off. I felt like they were honest about what I needed, didn't try and up sell me things I didn't need and respectful when I asked for time to consider my options. Once we decided to go with them they scheduled us with in a week. The install was fast and I barely even knew they were in the house. Everything is working great and we are really happy that we decided to go with a local company. I am very picky and do extensive research before any major purchase. Frederick Heating and Air has excellent reviews, provide a great value, excellent warranty and professional service.
