Gavin and Zac installed a new furnace for me. The were very professional, kept me informed on what they were doing, cleaned up after the job. Was very pleased and would highly recommend William Masters and their team!
Zack, Parker and Tyran were great.These three guys worked well together, were on time, hard workers and got the job done quickly. They replaced our ac and furnace.
We had a good experience in the past with them, we then bought a furnace from them. They did ok, the cover they made for the filter doesn’t fit and drives me crazy. An exhaust pipe was leaking condensation and they came out to fix it and they didn’t fix it right. I ended up having to fix it myself. Our a/c had an…

They are very driven towards customer satisfaction with high quality work, attention to detail and looking to the future needs of the customer. Assuring that the installation was well thought out, and executed. They cleaned up the…
Furnace & A/C installation by Zac, Gage & Jordan. Excellent job removing the old system and installing the new system. They were careful with the house/flooring, did a great job of cleanup and completely walked is thru the new system. Fully satisfied & highly recommended.
Gage & Jordan did a great job with my HVAC installation. They treated me and my home with respect and left everything spotless after the job. Very professional and courteous. They checked with me before drilling and explained everything in detail at completion, answering all of my questions along the way. Done with…
Masters came out and did our annual winter check and replaced our whole house humidifier. Did an amazing job. Zach is the best! Would highly recommend. I just had them put in a new furnace and Zac and Gage were fantastic!!!
Tanner, Jordan & Zac were at our house on 3/19/26 to replace our almost 30 year old heating & air conditioning units. They were prompt, covered my flooring, efficient & informative on the new units. I highly recommend Wm. Masters for your needs!
This past week I was awakened to the alarm of my C/O detector going off at 2:30 AM. After checking to make sure it wasn't low batteries and it was for real, I left and went to a family members house and first thing in the morning called and the RTFPD send one of the firefighters over with the meter and sure enought…
Prompt professional service.
Brad has been out technician for many years. He is amazing. We have had adjustments made on our heating and A/C units. They are new and had noise issues from the beginning. Loud noises out of the ducts when the heat would turn on and then the noise would lower after a bit. Our new A/C makes a horrible noise when…
Both Sales and Service were great - left area very clean after installation and service tech was knowledgeable. New furnace & AC installed with job completed and cleanup done in 7 hours! WM, Masters will be our go to for future HVAC & plumbing needs.
Tanner and Jordan did an amazing job installing my HVAC. They were very neat, orderly and cleaned up very well after.
Wm Masters replaced our HVAC SYSTEM in one day at a very reasonable price. They did two furnaces and one AC In about 8 hours with minimal disruption. Shawn, Barry, and all of the technicians were very quick to answer our questions and explain details. Overall, a very pleasant experience. Would recommend these guys to everyone.
Replaced furnace and added a new humidifier. Zac and Gage were excellent installers.
Recently contracted Wm. Masters for our HVAC system replacement. Shawn was our first contact for our quote, and he was timely, professional, and honest. Once we made our decision, the process again was smooth and painless. Great communication from the office and installation team. Tanner and Jordan communicated…
WM. Masters, Inc replaced our old furnace, AC, and thermostat. Zac and Gage did great work in great time. I would definitely use them again.
Had a new air conditioner and HVAC installed, they did an excellent job! After the installation they took the time to walk us through the new setup and make sure all our questions were answered.
We needed to replace our dual HVAC systems in our house. William Masters gave us a very fair price and the installment team (Zach, Gage, Gavin) did a great job with a difficult install (tight fit for the upstairs unit). Great job!
Would give more stars if I could. We had a lot of issues trying to get the right size of unit and price when needing to replace our AC/furnace. Trane brand is top of the line and WM makes it affordable. Their installers were able to custom fabricate everything needed for our install. Customers service is top…
