They are always courteous and polite - from the initial conversation with Joann to the service provided by their technicians. Larry has been out several times for maintenance on my heating and AC system, and he is always friendly and respectful of my property. He shared photos of his new grand baby last time he was here.such a proud grandpa!

Our central air unit stopped working over the holiday weekend. I called on a Tuesday, they were able to come out the same day. Our central air unit needed replaced. With sheer luck, they had a new slightly used unit available that they were able to put in on Thursday. In the mean time, they loaned us 2 AC units until replacement was completed. Great service all around. Will recommend to others and will continue to use them for further services.

Our first experience with them and it was wonderful! JoAnn over the phone was very pleasant to spreak with, got our appointment scheduled right away. They called while on their way, did the job quickly, cleaned after. We got our water line hooked up to our new fridge and Dillon did a great job. We will definitely use them again and will recommend the to our family and friends.

Thank you to the entire team at WM Buffington! The entire crew from receptionist to management and field technicians were kind, compassionate and professional. They insured that my AC was serviced and my damaged ducts were replaced. Now I can rest easy in a cool and energy efficient home! They will be my go to company for not just AC but any other services I need. Kellie Henderson

Our heat went out on early Sunday morning when it was 18 degrees. Since we have an infant in the house it was critical to have heat restored. Called Buffington and David, a tech came out within an hour. After evaluating the problem he found the failure but couldn't complete the repair since he had to contact a supplier. He assured me this was a priority and said he would call early Monday morning to advise of part availability and when they could install it.

As promised they called early Monday and scheduled a visit for 10am. Despite heavy snow and bad roads, tech Larry came and installed the part restoring the heat. Thank you for the prompt and excellent service when it was truly an emergency.

I would highly recommend WM Buffington to any friends or family. From Joann, listening to my concerns and then taking her time explaining the process and all financials, to Larry, our highly knowledgeable and thorough technician, WM Buffington exceeded my expectations. Thank you for your service. I look forward to working with you for years to come!

Buffington was once again absolutely amazing to work with! I've been using them for years and I am so impressed by their professionalism and expertise. No need to look anywhere else! At routine maintenance for my gas boiler, the technician noted an area of slight leaking in the copper pipes. Larry came and removed those areas that were faulty and replaced them with new copper piping.

He did it quickly and efficiently and very professionally as always. I'm so happy that I was able to find Buffington. The receptionist is absolutely amazing! I've never had a better customer experience! She's professional, thoughtful and very sweet! Buffington has always taken wonderful care of my home, both heating, air conditioning and now with the hot water copper pipes. I would recommend them unconditionally!

The gentlemen who came to install a new boiler and thermostat were pleasant, kind and courteous to my tenant and myself. They were professional and came prepared to complete the installation in one visit. After installation was complete, they ensured working condition and checked all the radiators in the house to make sure everything was working from the boiler to the rooms throughout the house.

I appreciate all that was done. Only ran into one unforeseeable issue, and even that was addressed professionally and honestly. Just waiting for the estimate of the cost to repair the pipes.

Dan Ball and the WM Buffington team were amazing. Dan helped us mitigate a problem and quickly come up with a go-forward plan that he executed quickly and professionally. I would and will recommend WM Buffington to anyone who needs plumbing and HVAC services.

George showed up promptly with a smile and a friendly hello. Additionally, he was very thorough with his diagnostic and explained his process to me as well as the history of my system. He provided me with his expert opinion on the life expectancy of our system, at which point he recommended a follow-up visit for a quote on a new system just to get an idea of what we could anticipate from a financial standpoint. All in all, George did a great job and I’d happily refer him to anyone that would need his services down the road!

Excellent customer service. They explain in detail what's wrong with your system and what needs to be done. Very professional

They did a very thorough diagnostic for a fairly low price (about 3.5 man hours for $80), which included calling the manager in for a second opinion. They gave me a good explanation of the issue, and stuck to the quote during the actual maintenance. The AC has been working great ever since.

Good service. Came out as soon as they could. Our call was an emergency, we had been evacuated by the fire department after a boiler malfunction. Apparently the boiler hadn't been cleaned in 2 years and was clogged pushing CO gas into the house.
Jason Kirby
Dan was top notch! Friendly & very informative; made sure I understood the issues with my heating unit and answered all my questions. I'll definitely be using this service again when it's time to fix or replace my unit. If you have any heating issues, give them a call and ask for Dan!
Claire S.
I felt very comfortable and they covered everything with me explained what needed to be fixed and gave me a total $$ amount. Having never used anyone before I was very happy

Excellent job! Fast and friendly service. Good communication.

I can't say thank you enough for being a wonderful company. With the installation of our new system some drywall had to be cut out and insulation removed. The guys were careful to place the drywall off to the side where it wouldn't be damaged so it could be used again, and they neatly stacked the insulation so it could also be put back in place. They also made sure to turn off any lights and left the room the way they found it.

Little things like that we greatly appreciate. They treated us and our home with respect and that is a big deal. Another thing we were super impressed with was Bill came back to our home both days the guys were here to install our new heating system, to go over details about the job to ensure everything we had discussed would be done. We were blown away by that, I can't tell you how much we appreciate you going the extra mile. Keep up the good work!! Thank you again

Excellent company! We use them for everything from heating / cooling to plumbing. Customer service is great. The technicians are very friendly and knowledgeable. They are a quality local company that you can count on.
Lisa Miller
Excellent customer service. Wayne was very knowledgeable and helpful in determining and meeting our insulation needs. He explained the various processes and we felt confident with our insulation decisions. All personnel worked in a professional and competent manner. We are highly satisfied.

At the end of April, we had Buffington replace our furnace and central air unit. Dan and David were conscientious, professional, and hardworking, keeping us informed during the day of their progress. They made sure we were satisfied and understood how to work the new thermostat before they left. We were extremely pleased with the end result. We use Buffington for our routine annual maintenance and for larger jobs (they installed air conditioning wall units at another property, as well as a replacement hot water heater).

Everyone we have interacted with at Buffington has always been very pleasant. We had tried many other companies in the past and we've always been dissatisfied with the service we have received, but not with Buffington, who we have used for the past few years. A bonus is that all employees put on shoe covers when they enter your home so as not to track in outside dirt and debris. We highly recommend Buffington!
