"Ivan did a tremendous job installed my ceiling fans. Fast communication and did quality work. One of our fans needed some drywall ceiling work done and it looks fantastic, blended in perfectly into the ceiling. Greatly exceeded my expectations!"

"Perfect! Installers were knowledgeable and professional!"

"Val did a great job. He responded to my calls quickly, arrived at my residence on time and prepared. He diagnosed a faulty ice-maker on my 13 year old fridge and located and ordered a replacement and installed it. It works perfectly."

"Amer was absolutely top notch. He came out in 30 mins on a Saturday morning to take a look at the project- rewire barn, new panel box, pool pump set up. He then came out as the pool was being installed, on his own, to make sure it was going well and to find out info about the pump for his part of the job. He came out a few days later and completed everything perfectly, went above and beyond and made everything aesthetically pleasing. After the job was completed, he then proceeded to walk me through everything he had done and explained why, and even going so far as to explain how my home generator works (weâ re new home owners), as well as upgrade our old dingy barn lights. We already have another project set up with him in for late summer/early fall. Amer communicated wonderfully, completed the job perfectly and went above and beyond. I canâ t recommend him any higher!"

"The new furnace and A/C were installed professionally and on time."

"My AC ended up “dying” and needed a new one. Richard was amazing. He installed a new AC for me same day my old one went out. I would not trust anyone besides him for anything AC/heating related."

"The service guy came out very quickly. Had a smart thermostat installed. He walked me through setting up the app. Did a fast and a great job. I highly recommend this company if you want it done and done right."
