Founded by Raffie Karabed — a civil engineer holding both a Class B General Contractor and C-20 HVAC license.
"Arkay installed a Mitsubishi heat pump system at our home. The team was knowledgeable and finished quickly — and always mindful to be quiet and clean since we have a small baby in the house. A few weeks later we had questions and Arkay came back promptly to help."
"I was impressed with his knowledge and experience. Raffie and his crew were very professional — they even sped up the job so it would be done before we left on vacation. Very satisfied with the quality of the work. We need more business people like Raffie."
"Raffie came out, did an energy assessment, and clearly reviewed options and pricing. Arkay installed all new double-paned windows and two sliding glass doors. Several years later the money continues to be well spent — cooler in summer, warmer in winter. Just do it!"
"Recommended through PG&E. Raffie took his time checking out our home, explained all his recommendations — and was not pushy. Workers were timely, efficient, AND super clean. At the end of each day you could not tell work had been done. Highly recommend!"
"Through the PG&E Advanced Home Upgrade Program, Arkay installed double glazing and added attic insulation — and I got a rebate of over $4,000. The work was thoroughly professional, and Raffie handled all the paperwork for the rebate. A real pleasure to work with."
"I've used Arkay three times — attic renovation, new double-paned windows, and a full HVAC replacement. Only excellent things to say. Raffie is thorough and delivers quotes with no hidden surprises. His team always shows up on time. Definitely on my A+ list."
