We were very happy with all of the staff, from the Comfort Advisor to the technicians and office support staff. The mapping of the new system was very thorough and important to the efficiency and performance of our new Heat Pump System, by expanding and adding air registers in the kitchen, bathroom en suite, and bedroom.

Tried other so-called HVAC “professionals” to fix our issues but only Tim was able to take care of our situation. He exhibited his professional skills in diagnosing our problem and explained the repairs he was going to make to us in a manner that we could understand. Obviously knowledgeable and also very friendly.

James D.

Everyone we have interacted with has been the best. Polite, professional, responsive. We had a new water softener system installed, some plumbing redone, and water heater service. Everything was completed promptly and professionally. They are also fast to respond to inquiries. They provide great service and peace of mind. Very good service. We will use them again.

Great service. Professional. The guys took a look. Quoted a price and were done and cleaned up in an hour. You get what you pay for! I’ve heard they are too expensive but it seemed fair considering the work done. Like I said though I could have found cheaper but who knows the quality? Not these guys! Quality!

Luis and Silverio were very professional, knowledgeable, and efficient. They took extra measures that protect our home and cleaned any debris. I would rate them both as exceptional. Luis mentioned that someone from Wighton may come back to do a follow-up on their work. That gave me a lot of confidence.

Louis L.

I had I believe James and Christian come help me with a shower drain. These guys really knew their stuff and I felt comfortable with them. They even helped me fix my smoker while they were here!!! Excellent job guys. You will be my go-to from here on out. Thank you!!!

David walked into a plumbing mess of epic proportions. One that many had been unwilling to help with based on the scope of work needed to be done. He could have chosen the path of least resistance, but he stayed at our place longer than he deserved to and evaluated every element of our problem.

Vanessa T.

We had a clogged toilet, bathtub, kitchen sink. Fonzi assessed the situation and gave us options on how to find a solution that worked for us. He did this politely and spoke in terms we could relate to. We continue to be pleased with their service and honest evaluations. Highly recommend this company.

Carol J.

Jared showed up on time and was very professional with diagnosing our HVAC issues. He fixed wiring and checked electrical connections to ensure no shorting issues. He diagnosed an issue with our circuit board tripping the breaker. He had replacement parts on hand and fixed the issue in a timely manner. Very professional, would definitely recommend.

Laura J.

Carlos was great! He was very professional, did a great high-quality job, and went above and beyond for us. Seems like all plumbers are very busy right now, and our service was delayed by a day because he got caught up on another job. But after seeing the quality of the work he did, it was worth the wait.
