TESTIMONIALS

Excited to share the love
we get from our customers

I had a furnace and AC installed this past week by Hawk Home Services. Amazing customer service from start to finish and best price and options. The installers were very knowledgeable and polite and made sure that when they left my system was running perfectly.

I am very pleased that Hawk Home have provided professional, responsive and good quality support, installation and well handled and communicated. Thank you to my customer service agent Sidrah who handled our service so well. We are very happy with our new installed tankless water tank!!!

We had a service technician come out to look at our tankless water heater that had started leaking. He called first and arrived on time. While he wasn’t able to fix it right away, he discovered what the problem was quite efficiently and informed us of what was going on. All in all, a good service call.

I got a problem with Enercare and I found HAWK HOME Service. I told them the story, and I wanted to get the tankless installation during the day. All my complications were resolved quickly. they are very friendly and helpful. Thank you so much for your kind and the services.
