As a family-owned and operated business, we take pride in our work. Since finishing high school, I have worked in the plumbing and HVAC field. My father built spec homes, providing my brother and me with plenty of work. I spent a summer working with my brother-in-law for an electrical contractor, then transitioned to air conditioning, heating, and refrigeration. I later earned my contractor's license and founded my business in 1994. I have continued to operate the business ever since. The Lord has favored our company.

Recommended Customer Reviews

Dunham & Son was referred to me by a friend highly. They came out the same day that I called, was glad because the A.C. was out and was very hot that day! Everything was right about the service provided and couldn't have been more happy with the outcome and every detail including a very fair price.

Have been a client of Guy's for close to 20 years...all in my family; an uncle, dad, brother, mother, partner, and I have all had furnace and A/C systems as well as maintenance and repairs by him. He is responsive, honest, reliable and efficient and provides excellent service....an all-around good, nice person. A 5-star business.

My furnace was sounding like an airplane engine and Guy came right out. He confirmed his suspicions and called about a replacement part right then and there. We agreed on the price and he said it would be a week. The part came in early , Guy called and came out on his day off and made the repair.
It is a rare thing for a company to show that kind of commitment to customer service. I would recommend them to anyone.

My A/C was on the blink a little bit. Guy diagnosed the problem quickly and made some good suggestions. My house definitely has some holes in the effectiveness of air distribution department, but by following his advice, it's made a good improvement. Thanks again!

Quick, efficient service at a fair price. All you can ask for.

I've worked with Guy on two occasions and he's become my go-to-guy for plumbing needs. He fixed a condenser pipe leak in my attic and installed a new water heater. Both times he was he gave me a quote beffore coming out and was here within an hour or two, being they were both emergencies. He charged me exactly what he said he would and had the job done in no time. He is courteous, professional and honest and I highly recommend him.

I cannot even express how grateful I am that Guy returned my call when I was desperately calling Air conditioning companies to fix a non working air conditioning unit in a rental. My tenant text at 6:45 am on Saturday letting me know that the unit was not working. He sleeps during the day so this was an emergency. I called 5 different companies and none were available until Monday. When I called Dunham & Son Guy picked up and I told him what was happening. He said he could come that day and I was very happy. I was happy that he was going to check out the unit, but I also thought because it was a weekend he would charge me a lot more then normal. Well, to my surprise Guy gave me a really fair price and fixed the problem just as quick. My tenant even text me and was so impressed with Guys work and his quick response. He was elated that the air conditioning unit was working again.
I would definitely recommend Guy and Dunham & Sons Air Conditioning company to anyone who was searching for repairs. Thank you again Guy, you made my tenants day.

I called this morning and was told that SCE shut off the air conditioner yesterday from 6pm to 11pm. Sure enough it worked fine this morning. Thank you for your kindness and honesty. I will definitely call you if we ever need repairs.

I have used Dunham & Sons twice now and each time was a great experience. Guy is very professional, honest, and reasonably priced. Today he fixed our A/C which he quickly diagnosed and had us up and running within a half hour. He doesn't pressure you with up-selling, but instead gives you options that fit your budget.
I will trust all future A/C needs with this company!

Dunham & Sons is the best heating ,air and plumbing business around . Our old blower stopped working and we were a little Leary on who to call because you know as well as I do in this position being hot without air conditioning in Hemet in August is a nightmare . Do yourself a favor and call Dunham & Sons for a professional , honest service..It's nice to know that there are businesses like this that are not out to take advantage of you ...Trust me look no further these guys are the real deal....
