Sam spoke with me on the phone and helped diagnose the situation. We made an appointment, he arrived promptly and examined our hot water heater to identify the problem. He explained that the leak came from the relief valve, and he replaced it. When I described a second location where water was leaking from our humidifier, he inspected that too and recommended replacing the filter. I highly recommend his service.

I had a new air conditioner installed by United Home Services, and I couldn’t be happier with the experience. I found them on HomeStars, where they had won awards and received fantastic reviews — and they definitely lived up to the hype! Ben reached out to me promptly, gave me all the details over the phone, and the cost was considerably lower than other quotes I had received. I asked him to come to my home for a closer look, and he booked the appointment right away. The installers were excellent — courteous, skilled, and professional. Other companies had told me that my deck would need repairs, but United Home Services team was able to remove the old air conditioner and carefully reassemble my trellis, saving me from having to repair the deck. I would highly recommend United Home Services Centre! They made the entire process easy and stress-free.Latest review:Install or replace airconditioning-
