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…

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…
The guys did a wonderful job. Tanner and Jordan were very professional. Would highly recommend them to anyone.
Had Masters out to replace a toilet. Was quoted an hour for the job, it took them over two hours. Naturally they bill by the hour. Install is fine, but the price was a good bit more than expected as a result.
The two service technicians l, Tanner and Gage were on time, knowledgeable, and seamed to perform the work efficiently. Since I don’t know the job, I can’t really evaluate the work. They cleaned up after the job, explained important information, and worked until the job was done. Couldn’t be happier. They installed a new furnace and air conditioner.
Wm Masters installed a new furnace and air conditioner in our home recently. Buster, Zac and Luke were great. High quality job. I'm really impressed with how quickly they were able to finish. They put a lot of effort into every detail. I'm so pleased!

Called Wm Masters on Monday afternoon and Shawn met us on Tuesday, listen to what we wanted and gave us 3 estimate by evening. Wensday we made a decision and were scheduled for Friday install. Tanner and Aaron showed up on…
My wife and I recently used Wm. Masters, Inc to replace our 23 year old AC and furnace. We also had them install a mini-split in our upstairs master bedroom. We were pleased with the entire experience and would recommend them to anyone looking for a company to complete HVAC work in their home.
Tory, Zac, and Gage were great. Installed all new heat and AC units and worked hard all day despite a few hour power outage. Great job.
My wife and I were very pleased with the professional work done by Buster and Gage installing new furnace and A/C units. We would recommend Wm. Masters , Inc. to anyone wanting installation or service done.
Tanner and Luke were very professional. They were experienced, and clean. One of them even petted my cat! Seriously though they did a great job replacing my furnace and a/c, I’m totally impressed, thanks
Had furnace issues, Tory came out same day, accessed the issue, ordered part and gave us additional options. Needed 2 new A/C units plus new furnace. Emailed quotes and ordered what we wanted. Zac and Ryan were out 3 days later, installed furnace and 1 A/C unit. Tanner and Zak returned to install second A/C unit.…
The process from beginning to end was excellent. When Shawn came out and gave me a quote, he was informative and I didn't feel like he was trying to sell me something that I didn't need. Quite the opposite actually. The system he chose for me is perfect. Tanner and Gage were awesome installers. Prompt,…

Professional responsive staff including having a maintenance technician back to my house within 30 minutes the next day when needed a minor adjustment. Tanner Gage and ZAC did a wonderful…
From start to finish WM was amazing. Our 20 year old heater gave up the ghost. They were quick to come out, assess the situation, quote and schedule installation. Added bonus, they had our new system in stock!! Buster and Gage were awesome! Professional, polite and skilled. They were absolute pros with the…
Buster and Gage were wonderful, did a great job on the install, old furnace removed, new furnace installed, no mess afterwards. Very personable and professional!!
I wanted to replace my furnace before it failed and get a new power humidifier. We called WM Masters for a second quote because we've had positive experiences with them in the past for plumbing. The price was significantly cheaper for the same quality product and service vs the competitor who gave us the first…
