I was looking for an AC service provider that came across as honest and skilled at their profession. Dominic checked those boxes! I'm looking forward to with him and his wife. They seem like a great team!
Review
Always great service. Prompt. Very affordable. I’ve been using Dominic for four years now. Only needed a couple of repairs during that time. Very reasonable prices. I have him come out every six months to tune up the heat pump
Review
Dominic has completed two repairs for me in the last 6 months. First my blower motor went out, which he repaired, then a few months later my fan stopped working and he came to fix that. Scheduling was easy, Dominic was honest and didnt try to upsell me into something I didnt need, and his pricing was very reasonable. It's comforting to know I have an honest HVAC company to reach out to when I need them!
Review
One of our A/C units was not blowing cold air and Dominic came out on short notice. He immediately introduced himself and was very respectful...even asked if he should take off his shoes in the house. My wife would very much appreciate this! He was very thorough in explaining the issue and what repair options there were and the associated pricing. He even discounted a few things. Very transparent and I never felt pressured!! He was able to make the repairs same day and get our unit back to functioning correctly. Would highly recommend you consider Dominic for your HVAC needs.
