AC quit working over the weekend. Called Petitt on the advice of a neighbor, they were here within an hour. Long story short, they got a 16 year old unit going again. After speaking with Brett and Randy, decided to get a new unit. My options were clearly explained. The guys came out today, installed the new unit and air scrubber. Everyone I interacted with at Petitt was professional, knowledgeable and personable. Absolutely recommend these folks. Thanks, Petitt H&C.

Our A/C wasn’t working on a Saturday afternoon. Petitt Heating and Cooling arrived within an hour and repairs made in 10 minutes. They had all parts needed in their work van.

Came home to a 80 degree home. Called Petitt and within 30 minutes Brett showed up. Brett did an awesome job! He’s a very polite young man. Explained everything that he was fixing. Ended up being a quick fix but also discovered we had bacteria growing. He installed an Air Scrubber and a UV light so we can have better breathing air. Thank you for such a quick response!.

Very professional!! Excellent work. I could not be happier. The technician showed me every detail of my AC unit and explained what needed to be done. There was no hard sell. Only recommendations and the benefits that come with doing them. My unit is now performing way way better. The air is cleaner. Smells good and is removing more moisture out of the air. I highly highly recommend going with this company.

Thank you to Petitt Heating and Cooling for helping to resolve a minor issue that had become a big problem. We had water backed up in the drain pipe and then a part outside failed, leaving us with no air on a very hot evening during the summer. They replied and served us both times within 30 minutes and completed the work and fixed the issue. They were polite, excellent and efficient.

We have used Petitt Heating and Cooling for many years. We recently remodeled our home and added a new unit. The whole team is wonderful!! From the first call, to the installation, everyone is top notch. We also have a maintenance plan with them. We don't have to remember when to schedule our maintenance. We receive an email or a call to keep our unit running smoothly. This is important for our busy family. Give them a call, you won't be disappointed.

I can’t say enough about Petitt Heating & Cooling! Logan was professional, courteous, and took excellent care of our AC unit. With close friends traveling from out of town to visit this week, I was so worried when our AC unit stopped cooling. Logan diagnosed the problem quickly and had it fixed and running much faster than I expected. Petitt Heating & Cooling will be our go-to for all our heating and cooling needs and we’ll definitely tell our friends and neighbors about the outstanding service you provide! For affordable and reliable service I highly recommend Petitt!

I've been a customer of Petitt Heating and Cooling for more than 10 years. Mike and his crew have always done an excellent job keeping my home a/c unit working properly. Mike even came out last summer while we were out of town and fixed our A/C while we were on vacation. Brett was by last week and serviced the A/C unit to get it ready for the hot summer. Thank you Petitt Heating and Cooling for a job well done and I look forward to many more years of being a raving fan!

I had Petitt Heating & Cooling do a full tear out and replacement of my duct work and HVAC unit. Randy and his team did a stellar job. They were in and out in one day and were very professional and courteous with their work on the inside and outside. They cleaned up everything and left my property looking better than it did before they arrived. I would highly recommend them for your HVAC needs.
