Customer Testimonials

David from KD & Sons came out a few days ago when my AC went out. He was here in a few hours, even though it was late at night. He was polite and professional, explained what he was doing, showed me what was broken, what he was replacing, and why. He took the time to check the furnace too, and didn’t try to sell me anything I didn’t need. The price was very reasonable, they warranty their work, and it was nice for someone to take the time to explain everything to me. (Especially since I was afraid I needed a completely new unit, it was great to hear I could probably get another 3-5 years out of my current one!) They were in and out of here in about an hour, and they cleaned everything up like they were never even here. My AC has never worked better. It cools my house quicker, and my entire house (even the upstairs-which never gets as cold as downstairs) actually got COLD for the first time in 5 years! I will absolutely be calling KD & Sons for any future issues. Call them before you call anyone else!! Thanks again David!

Great Company, Great Service. I had a furnace go out at one of my rental properties I manage. The home had children in it that I was concerned about. Dave talked me through the troubleshooting and we had it running in no time. I was very thankful that considering the circumstances he was willing to talk me though the issue. Most companies would have refused and made their money on the service call. Great guy and would definitely recommend them.

It’s not every day you find a company that is run by people who are honest, kind and truly care about their clients but that describes KD & Sons to a tee. When my furnace was being temperamental my husband had to keep messing with it because it kept going out so we knew we needed to have it looked at. When I messaged KD & Sons on FB it was fairly late in the evening but they responded almost instantaneously. Since the furnace wasn’t out at the moment we scheduled a service call for the next day but they insisted we call right away if the furnace went out over night. After they fixed it (for a good price and didn’t try to sell us stuff we didn’t need) we liked them so much we chose to also use them for dryer vent cleaning and duct cleaning. We’re extremely happy with all of the services they provided and I’m super grateful that now we’ve got someone that I know we can trust to call if we ever need help with HVAC needs. I also plan to have them do the routine maintenance and microbial spray to keep the air in the house good quality. Great company and awesome guy!

I called the owner Dave at 6:00 pm on a cold night when my furnace went out…he was at my house by 7:00 pm. Dave had the problem diagnosed in minutes and ordered the part that night. The next morning he was there early and installed the part in no time. Furnace is running great! Thanks!
