5 Star Reviews

“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!”

“Ray was an amazing professorial and showed me everything so I could make the right decision for my home. I highly recommend Ray for any homeowner. Also his amazing responsiveness was outstanding. Came on Sunday and replaced the furnace on Monday! Thanks Ray!”

“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).
