I am so glad we went with Mercury for our new AC system. Ray showed up quickly with a mask on for a quote and answered all my questions. We got a quote within a day, which took some companies weeks to get to us. The quote was extremely reasonable.

Ray and Ryan came and set up the system over 2 very hot days within a couple of days of us asking for a date (some companies had up to a 4 week wait list). They were friendly, clean, and did a great job setting up our system and fixing some existing issues in our ducts for free. We couldn’t be happier with them!

The Experience was FIVE STAR! When we needed someone to be there, Mercury Heating and AC made sure the AC was working when my son was released from the hospital. This kind of company and their response is very much appreciated. Thank you Ray and Mercury!

Neal is a friendly, efficient and professional technician. He installed my garbage disposer in under an hour and then explained how it differed from my previous one and how to care for it. Really nice guy! Overall, the response was fast after I reported needed a new one in Home Advisor and customer service was excellent.

Extremely responsive (even on a Sunday), reasonably priced, and excellent work. Within minutes of having issues with my garbage disposal this past Sunday, they were at my location with a replacement. Highly recommend.

Ray and Zach were very thorough in removing my old furnace, vacuuming the entire closet before putting in the new furnace. They were very careful not to track in any snow or dirt, they put down drop cloths to walk on. They made sure I understood the thermostat before they left. They completed the job in speedy time. I thank Ray and Zach again for a job well done.

Ray was very knowledgeable and gave a great competitive price. They only took a few hours to install my furnace. They were on time and answered all my questions. I had about 3 other quotes that were not even close. I would recommend to others for their great service!

If you need to have something fixed or newly installed, Mercury Heat and Air Conditioning is business to do it. Within 1 hour I spoke with owner, Patrick, via phone and received a quote and service Tech named Neil arrived shortly after had the job done completely. Now that is 5 star service. Will definitely use them again. They certainly can help with many issues you may have.

Ray was professional and well informed. Didn’t try to over sell options and met my schedule even though he had the work to do on Sunday. Trouble shot the problem and presented options for solution with costs of each. Did all the work in a timely manner having all equipment and making sure it was kept clean with runners . Cleaned up everything. Would highly recommend.

I am thoroughly impressed with this company. I would highly recommend hiring them for your air conditioning/furnace needs. Patrick and Ray were amazing to work with. I was without heat for 2 weeks (due to snow on the roof where my furnace was) and the 1st night they brought me multiple space heaters to warm my place. They kept in contact with me throughout the process giving me updates and eventually fixing the issue. They cared about my well-being and wanted to make sure I was comfortable. I cannot thank them enough for getting this fixed for me! Thank you!!

Mercury did a great job for our store. If you want a great team doing a great job at a good price this is the place. Support local businesses that do solid work!

Ray made it out on the same day I contacted them (which incidentally was a Saturday). He was very knowledgeable and professional. He was able to replace my deceased furnace first this Monday morning (which was great because another cold front was on its way). He did a great job installing the new equipment (very neat and detailed). I will recommend them to others and I intend to use them again (I have a pending AC project that I will likely do in early spring).

They were very professional, friendly and provided excellent service. Ray explained everything and provided us with different choices given the condition of our furnace. The installation was professionally done and he worked continuously to complete it in a timely manner. I highly recommend this company.

I recommend this company 100%! From the owner Pat to his employees Ray and Ryan who worked tirelessly to find out why the new a/c unit they installed kept freezing over. Ray and Ryan put in a lot of hard work and hours only to find it was another Heating and Plumbing company’s mistake. They are definitely dedicated to say the least and I am forever grateful to have my new ac working in these hot days of summer!! Thanks again Ray and Ryan!!!

I’ve used Mercury twice now–once to replace a furnace on a Sunday in February and a second time to fix an AC unit that had the fan motor seize up in July. Between the two service calls, I’ve dealt with Pat, Ray, Neil, and Ryan and they have all been great. I think what I appreciate most is that they have been extremely honest and fair when they could have added emergency surcharges. I highly recommend them for their responsiveness, professionalism and honesty. Plus they’re just friendly guys.

This company came in and hooked my swamp cooler up to a thermostat. I was impressed with them then, so when my swamp cooler died and I decided to upgrade I didn’t hesitate to call them. They were efficient, friendly, and worked with my schedule getting my new air conditioner quickly. I would definitely recommend this company!
