"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"Extremely satisfied & pleased with the work performed by Elm. Eric, Rob & Jesse were great on the installation – on time, neat, careful to show us the status as they went through the job. Have already recommended Elm to neighbors who expressed interest. Scott was great on the initial review & estimate & Cathy in the office was extremely helpful as well. Thank you to the whole Elm Team!"

"Professional,prompt and attentive. The previous company installed low quality parts and I continued to have problems. Surefire installed what appears to be good quality parts and my heating system is still working. I would definitely use them again and would also recommend to my family and friends. They are also reliable and prompt. They gave me a window period between 8-10 and they arrived at my house at 10:00. Many companies will have you waiting all day but not Surefire. I want to thank them for a job well-done."

"Kevin and Sal did a phenomenal job installing our new state-of-the-art HVAC system. This father-and-son team is incredibly hardworking, professional, efficient, reliable and accommodating. Kevin, who has worked in this business for many years and is extremely knowledgeable about energy-efficiency and environmental improvements, shares his expertise with his son, and it’s a pleasure to see them work side by side. We were referred to Kevin and Sal by our nephew, who had found them on Angi’s list when he needed a new boiler. He had told us they are customer-focused and strive to do the best possible job from start to finish—and he was right! What's more, after completing our HVAC installation right on schedule and reviewing every aspect of the new system with us, they left our home cleaner than it was before. We couldn’t be more impressed with all of their high-quality work."

"A/C wasn't cooling and service tech did some testing. He found that problem was minor and was able to bring our old unit back to life. His quote was fair and we would use him again"

"The installation of my Hvac system could not have gone any better. Joe was on top of everything from contacting me when he couldnt make the original installation date, to following up and waiting on me to have the electrical upgrade, was on time and punctual both days its took to do the work and made sure he explained everything and I had a clear understanding of everything. I would definately recommend and hire again for any Hvac needs"

"I am very happy with Mikes Air Conditioning. Here it is JULY and I while in the middle of doing some renovations to my home, I noticed the AC wasn't working the way it should be. I contacted Mike's (fearing the worst) and they sent out a service technician who was able to repair the system for a reasonable cost and buy me some more time before I have to replace the entire system. I had some minor work completed and the freon topped off and now I'm cool and comfy!  Considering all of the expenses with renovating I was very happy to not have a high repair bill. Mikes was efficient, conscientious and professional and they completed the job on time and for a reasonable cost. I recommend them for AC repair as well as installation of new units. When I'm able to replace my system, I'll be calling Mikes Air Conditioning to do the job. Building relationships and getting repeat business should be the goal of any business. I'm glad to see that Mike's takes customer service seriously.

"I called in the late morning and the friendly office person took down all my information and gave me a window of time between 2-4 PM. She later called and said that the serviceman got done early with his morning job and would like to know if he can come earlier. The repairman, Andrew, was professional and knowledgeable. He opened the heating system access doors and found an error code. He promptly fixed the issue and also cleaned another part, which he said could give problems in the future. He took the time to explain why the problem occurred and what he did to fix it. He also took down the make/model of the heating system in case it needs more work in the future. Since there were not parts required, I was only charged the minimum service fee. The heat is working solidly now."
