Excellent service. They are quick to schedule. John, the owner, is very knowledgeable and made sure I was informed of everything he was doing. I initially called to get a smart thermostat installed and he ended up helping me with so much more, including getting the humidifier we had in our house from previous owners up and running, and getting me some of our specialized air filters. I ended up having him come back to install an air purifier. A+ - will use again and highly recommend.

We were having issues with our furnace and it needed replaced. They came out fast and replaced our furnace & Ac at a very affordable price! I highly recommend
What a great experience with Johnny Stubb’s Mechanical. Our A/C was not working properly and we called based on other recommendations. Everything from the initial call to the service appointment was very friendly and professional. It was refreshing to use a service provider who was reliable and honest.
Matt came out last minute and replaced a whole house fan and crawlspace fan. Went above and beyond the call of service! So happy we found Johnny Stubbs Services!

If you are looking for a very dependable, fairly priced HVAC Contractor that does top notch work then look no further than John and his team at Johnny Stubb's.
Our heat went out on the coldest night of the year and John came so quickly and fixed our heat and got us up and running again. We were really panicking for we had two young infants In the house. I will call him again and again
