Super nice guy, came and fixed our crazily wired HVAC system that also had piping, tubing and every other issue under the sun. He replaced our thermostats too. Very efficient, fair and easy to recommend. Thanks Gavin and Danny! read more

I have been having Danny Oliver HVAC service and maintain my home's heating and air conditioning equipment for several years now. They do a fine job, the staff and techs are always pleasant and informative and the prices are very reasonable. I highly recommend them! read more

A couple of weeks ago our AC stopped blowing. I called ANOTHER company found on Yelp. The kid came over ($40) to see what the problem was. He identified the problem as the blower motor. I asked him to do service maintenance on the unit, essentially spraying it off with water. ($159!) The estimate to replace the blower motor was $1600; $900 for the motor, $700 for service. Instead I purchased it online. My husband is super handy replaced it in 40 minutes. A few days later the air was blowing but not being cooled. I found Danny on Yelp and called in the morning. He came at the end of his day, diagnosed the problem and replaced the part in about an hour ($150) His $75 diagnostic fee may be higher than the other company but completely worth it because he doesn't price gouge and got us up and running on a very hot day. It's looking like we will need to replace our system in the next couple of years and when we do there's no one else I would trust. read more

Meticulous and fair, that's Danny! Other companies will do the bare minimum, but if Danny finds something out of the ordinary or unsafe in your previous set up, he will bring it to your attention and mitigate it. He's thorough and does great work, we are so happy with the upgraded ac and furnace he installed. I would recommend him to anyone in Penn Valley/GV. read more

Danny's the best! We shopped around extensively and he has the best prices and best service, super sweet guy too. Do yourself a favor and give him a call, tell him I said what's up read more

Showed up at the last minute to diagnose a furnace issue for us. He arrived promptly and was able to suggest a solution that worked for us. He came back, did the job, and left a clean workspace. We did most of the transaction (estimate, payment, invoice, receipt) online, so it was super easy. read more

Danny was great! Easy to schedule, great prices, very honest and thorough. We got our A/C serviced and he checked on our furnace as well. He was able to give us details on how it was doing and how it should hold up based on its age. Thanks Danny for your help! read more

Great communication and showed up when he said he would. Installed a Nest wifi thermostat for the price quoted. Recommend him highly, he knows hvac. read more

We had to have a new furnace as our old one was just becoming too problamatic. We called Danny and he came right over and gave us an estimate which we accepted. He immediately made arrangement to get our furnace here . He had a lot of customers waiting but because of my bad health he moved us to top of his work order list and got our new furnace going as fast as possible, It's rare to see excellent customer service like Danny displayed any more and I am very, very pleased with his service and would recommend him to one and all. read more

Danny installed Hvac throughout my entire old house and did an amazing job! His quote was competitor but what made me hire him was his overall vision. While others wanted to install mini split systems on the Wall, Danny did a ducted mini split system so it appears like any other central heat/air system. read more

Danny did a great job! He was beyond helpful and made sure he did the job right. I turned on my heater for the first time of the year and I realized it wasn't working. I gave Danny a call and he responded quickly and fit me in that day. He ordered the parts and was back the next day to o fix it. He was polite, respectful and timely. I'm warm, cozy and ready for the cold months to come thanks to him. read more

Danny showed up on short notice wearing an N95 mask and fixed our AC in a very efficient, professional manner. Kudos

Danny came out and did a generator maintenance check...including an oil change and filters. His cost was very reasonable. He is polite, friendly and responds quickly. I have called him out again to investigate a possible heating duct problem. read more

Danny came on time. He was professional and friendly. He serviced our heating and air conditioning units. Great price!
