ALL GOOD!!
Description of Work: I was glad to find this referral in my 209 area code, as the services needed were in Concord.(Area Code 925) Dave was efficient, punctual, flexible, and trustworthy. The assessment of the A/C problem was correct and service was accurate and timely. Since the summer service, Dave has been out to service the heater and set the new thermostat.

We had mold in our system. He evaluated the system. Once we had the mold removed he came back and did the repair. They were very thorough and a job well done. Insurance is paying by the insurance company. I asked him up front because I really wanted to know what he was doing and get an impression about the ac system. I am always trying to learn something. I asked if he could listen while I talk and he said oh sure, ok. So from time to time I went and asked him questions about what was that for and what does that do and how old is the system. I got a lot of information that he was willing to share. Everything that he needed to to to un clog the drain system is working well.
Description of Work: We had Diablo Valley Heating & Air come out and repaired our heating and ac system.

This contractor looked at my 2nd house inspection report and gave me an estimate of $275 to finish the job as described in the report. He did five things in one hour, and would have finished quicker if he hadn't been so patient and helpful explaining things to me very clearly while showing me what he was doing. I don't think I've hired a contractor in the past year who was so stress free to deal with, did more than I expected, treated me professionally and was very clear with no surprises. He not only sealed the insulation the previous contractor didn't seal, but corrected several mistakes to properly cover the unit before sealing it. Several professionals noted that the outside A/C unit was too close to the house, but this was the first person who checked to see that it wasn't bolted to the ground and just moved it out a few inches to correct that problem. So he actually fixed two things that I didn't expect him to, and the total cost was $100 less than the estimate! I would certainly hire this company back, however, if you need ducts cleaned they don't do that. Great Guy!
Description of Work: A previous HVAC contractor recommended by my Realtor didn't finish their job and ignored every agency that tried to get them to finish it, so the State Contractors License Board told me to hire someone else to finish the job. I used an ad in the monthly magazine after joining Angie's List. He finished sealing the insulation around the HVAC unit in the closet, and corrected faulty insulation work before sealing the duct to create a necessary gap between that and another hot vent pipe, pulled the HVAC unit as far from the house as possible because it was too close, and fixed a vent that the previous contractor didn't reattach correctly and was falling out of the ceiling.
