"The old air conditioner was installed after purchasing new windows. The window company installed it as though it would never be removed. The prior handyman could not remove it after 3 hours of trying. Ivan and his worker removed it in 30 minutes. The entire job was completed in less than 90 minutes."

"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."

"Tom was prompt and thorough, and worked tirelessly to do a complete and excellent job. I was impressed both by the quality of his work and the speed with which he accomplished it. He actually did 3 different jobs for me, including installing an awning, repairing a pool and installing a new liner, and replacing 75 feet of discharge pipeline. He can do anything! I would highly recommend hiring him."

"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."
