Heat Pump Installation in Other 95941

“Duncan’s Heating and AC is over-the-top! I have done business with them since 2013; and they have been great. I first contracted them as a 1 year installed Central Air and Heat System was installed by a company in Grass Valley no longer wanted to come to my homeband doing any servicing anymore. I was dumbfounded to say the least. A few months after the “Coleman System was installed the system shutdown; the Grass Valley Contractor did come out; said the mother board was fried. It took 3 months to get one. Only one year of service. This one did last a year, and they claimed too busy. I searched around and contacted Duncan’s. They got out in a couple days. Motherboard again, they found that the Coleman was not making parts for these residential systems. Got a universal one and installed it. I had them do servicing all the time afterwards. 2024 the system went out again. I had purchased a house warranty through American Shield…what a joke. They called a guy out who spent 4 months whining about what the issue could be…claimed no codes were listed, but he felt it was the blower. I contacted Am. Shield demanded different guy. They agreed but I had to pay $200.00, I did not care. The day second company was to come no one arrived, called I was told insurance cancelled. Called Am Shield, was told the first Company sent report finally. They told me it was the blower and they would pay $255.00 for the replacement part, but because the guy Jason also detailed $9000.00 for modifications. I told the insurance guy he was stupid; that a new unit should be bought they refused. Closed account. Called Duncan’s. Arrived next day. Blower out., system obsolete, no parts, should have been replaced. Duncan’s service guy informed me he could rebuild it, but they could not guarantee how long it would last, but hoped it would give me time to be able to replace unit. The blower rebuild gave me two years to build up credit and put back money so I could handle everything, without getting a huge loan. Needless to say I had Duncan’s put in the new system. Duncan’s Heating and AC Co. is a small company and absolutely all about good service. Every person from them I’ve dealt with has been highly professional, polite, friendly, respectful and knows what they are doing. They are the only people I have servicing my unit.
They are fantastic people, they care about their c”

“Duncan's Heating and Air is amazing. My new HVAC system failed right at the beginning of the summer and after several outrageous estimates from various HVAC companies a friend referred me to Duncan's. They came to my home in a timely manner and gave me an estimate that was several hundreds of dollars below that of the other companies. They were quick to schedule the repair appointment and the tech was able to repair my unit within a few hours. I am so impressed with the kindness and professionalism of this company and I highly recommend them to anyone needing service for their HVAC system.”

“Andrew installed a split system ac unit for us. He was punctual and did nice work! (Felt bad for him, he continued working to get the job done, even in the rain). It was a seamless process from the schedule to job completion. We will definitely use Duncan’s Heating & Air for future needs!”

This is definitely a five star company and I would highly recommend them for your AC and heating needs. With the heat index in the 109-111 range and 92-95 in the house it has been tough keeping cool without AC. Our AC went out on Friday night and I called Samatha first thing Monday morning and explained my husband was frail and having medical issues and I really needed help. She worked us in on Thursday and the Tech Rob was right on time and had us up and running in about an hour. What angels they were to help us in a sort of dyer situation and we are extremely grateful. We are eternally grateful for the kindness and professionalism this company provided us. They set the bar high and are a shining example of what we remember to be excellence in service. Thank you Duncan’s
