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…
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!
Our furnace blower went out over the weekend and do to the age of hvak decided to replace. 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,…
Installed new AC and Furnace. Tanner and Gage where very professional and did a great Job. Would highly recommend Masters

Buster & Tanner were great! On time, efficient, professional, and knowledgeable.

Selected Wm. Masters to do a complete replacement of my 30+ year old HVAC system. Competitively priced and completed in one day. 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…
First class operations from phone call to service and from quote to installation. We purchased a new Trane furnace and a/c unit. All spelled out and communicated clearly. They even helped repair my old thermostat while I was on vacation. Very satisfied customers!
Really efficient and painless installation of a new furnace, heat pump, and water heater. Our furnace/heat pump installers,Tanner and Zac were friendly, explained things well, and thoroughly professional. Our water heater technician was equally good.
The union craft local training is very apparent in the quality and performance of Wm.Masters, Inc service technicians.
Trust the reviews. Wm. Masters sets the bar for service excellence. Our 90s systems had simply aged out and ultimately failed. We requested a project to install new furnace, A/C, humidified, and supporting duct work. An appointment with Shawn was promptly scheduled to assess the space and provide options.…
Tanner and Buster did a very professional job. Polite and explained the whole system to me so I could understand.
Buster & Gage were efficient and professional in everything they did. Wouldn’t hesitate to recommend the company.
Tanner and Zac were excellent! Very professional the entire time at our house. They were polite, very kind & most of all patient. Thank you gentlemen!
I recently had a full HVAC replacement done and would 100% use WM Masters, Inc again. The salesman Shawn came by to assess our needs and gave me several options at different price points to choose from. I then worked with their materials guy to determine a date for installation who again was very pleasant to talk…
Jonathan and Gage installed a furnace and air conditioner. They were quick and efficient and did an outstanding job. They went over the systems and explained maintenance and next steps. I recommend Wm Masters.
We had a new Trane furnace and air conditioner installed by William Masters. Tanner and Zac were friendly, courteous and professional installers, and completed the work sooner than I expected. I appreciate the time they took after the installation for us to review their work and the operation of both units. Every…
We have been using Wm. Masters since we purchased the new built house 27 years ago. They have provided maintenance service for both the air conditioning and heating twice a year since that time. We knew the typical life span is 20 years. Last Friday at 4:00 the air conditioning stopped working. By 4:30 someone had…
Had an older system replaced last month, and Tanner was particularly nice when I asked (if possible and easy) for the cover around the old AC system. (My raspberry bush is growing rapidly now that the critter bothering it can't reach the bush.) Thanks for that extra effort! Always a pleasure to deal with employees of this company.
Great work Zac and Tanner. Very professional and will highly recommend. Thank you
My installers were Tanner and Zac. They were punctual, polite, cleaned up and were and extremely efficient. Kevin the tech was honest and helpful and Shawn who provided the estimates was forthcoming and extremely considerate, and got up a in the schedule in s as very timely manner. Kudos to all!

Thanks to Buster and Gage for their excellent and efficient work installing our HVAC system. They were pleasant, hard working, and provided what they were going to do clearly and updated as they went along, and also how a problem discovered will have a followup from the office.

Buster and Gage showed up on time. Completed the work quickly and neatly.
My AC went out at the same time as my furnace! Todd came out looked it over and was super quick (same day) getting me a quote. It had been in the 90'S that week and I have a sick elderly person in the home. There quote was great, he was not only professional, but understanding and worked with me to get my equipment…
All contacts and installation aspections performed by William Masters has been top notch. Great company to work with - thanks for all that you did. Thanks to Shawn, Buster & Gage who did all the on-site inspection & work. Bravo!
When our AC went out after 31 years, we called Wm Masters to determine what our options were. We initially worked with Shawn who looked things over and provided us with options to replace just the AC, or both the AC and the furnace (also 31 yrs old). After deciding to replace both, Barry helped with scheduling and…
Buster and Gage did a wonderful job with the furnace and AC replacement/installation. They arrived on time and got the job done sooner than I had expected. The sales person did a wonderful job as well getting us set up with the best system for our needs. Thanks
We replaced our 30+ year old heating and cooling system with Wm Masters. They made it rather easy. Their technicians (Zac and Tanner) were great, they were knowledgeable and helpful. The install was scheduled in less than a week and completed in less than a day. We highly recommend Wm Masters!
The motor in our existing airhandler quit working and they came out the next day because we were without heat. We decided to replace the entire airhandler and Wm. Masters worked to get one that would fit ASAP because we were without heat. Zac and Tory were very professional.
Very impressed with Jonathan and Zac! Professional, clean up was great and laid flooring protection throughout the entire foot traffic area and wore shoe coverings…….Top notched! WM has installed our central air, furnace, air purifier and humidifier. Very happy clients. Christine Pistorius

Jonathan and Zac did a good Job! fast and well done, answered my questions
My A/C went out last summer, and I knew it was time to replace the furnace as well. I've waited to review until both were used, and I've found that both work well. Wm. Masters, Inc, responded quickly to my need for a new system. They were helpful in answering my questions about various models and helping me choose…
Installed new HVAC System yesterday.. Jonathan's install work was outstanding and he was assisted by Gage and Chad. All three were courteous, careful and polite. Thanks for doing a great job..
I was experiencing respiratory symptoms due to an air quality issue. I eventually realized it was an HVAC issue, but did not know the cause. William Masters Co were called and responded quickly. At the first visit, the service tech diagnosed the problem and he was correct! Within a week they had replaced failing…
Tuesday, Oct., 19th, three men, Aaron, Tanner, and Zac, from Wm Masters, came to our home in Bloomington, to install a new furnace and air-conditioner.
