No rush fees or weekend charges, just a simple fix. I sent pictures ahead of time. The guy was in and out in a half hour. I asked about the huge charge and someone called back promptly. He was very friendly but made it clear... that's our price. I live around the corner and I always like to work with my neighbors. I guess everyone isn't so neighborly.

I have a very old AC unit that's in the attic and I wasn't very optimistic but after about an hour of working on it Alex got it working again by replacing a fan and installing a new thermostat that was compatible with new part. He has to work hard as it was warm that day and probably 90 degrees on the attic . Alex was very professional and personable. Price was incredibly fair . I would recommend and I will use Alex and his company again.

I spent many days doing research and determining the correct system to replace an older inefficient…read moreoil furnace with a new Natural Gas High Efficiency Furnace and Install a Brand New Central Air System. I learned from reading many articles knowledge is the key to correctly sized and properly installed HVAC systems. Undersized or oversized systems will just leave you uncomfortable and paying higher utility Bills. Armed with knowledge I called local contractors for bids, and received estimates from 5k-12k and the furnace sizes ranged from 58k-120k Btu. In doing calculations using popular DIY sites I had come up with 65,000 Btu Heat and 30,000 Btu (2.5ton) cooling. Derek (Owner not some sales guy) quoted me on an 80,000 Btu 2 Stage Carrier Furnace so in low heat mode it's perfect for maintaining temperature but after setting the temperature down at night the High Heat Mode Brings my house back up to temperature quickly in the morning. Other Contractors were quoting Goodman and Comfort Air products for the same or even more money. The Day of the install Derek and Nathan showed up on time and got right to work removing the old furnace and oil tank. A conversation with Nathan revealed he was a High School Student in a Vocational HVAC program working for Derek. I was amazed at his attention to detail and professionalism being so young, his passion for what he is doing really showed with his nice neat bends of the tubing to the AC Unit. Several Hours later I had Heat, and it was so quiet, simply amazing how quickly it was able to heat this old house up. Derek went over the system with me and completely cleaned up, the only evidence he was here is the new equipment. If you need a Knowledgeable, Dependable, Friendly HVAC Company Dagesse Heating and Air is the only choice, I will recommend them to anyone, if you want a referral just ask Derek for my number and give me a Call.

The phone was answered by the third ring by a man who obviously was multitasking like crazy! Turns out the phone was answered by Alex himself while he was in the middle of doing another job!! He was straightforward, telling me he is extremely busy but could come 6/1/22 between 8-10:00AM, just 10 days away. I said ok. He came right on time June 1st, texting me before he left with his ETA. I expected him to come, look and then tell me what was wrong setting up some time off in the far future to come back and repair. Nope. He said he carries lots of parts in his truck and usually can fix units right then and there. Let me say he is a smart & driven young man. I learned more about AC units from him in the short time he was here than from any other AC person. He is really big into educating you about your system which I totally appreciated . He told me maintenance is a big thing, suggesting that an occasional rinsing of the fins with a hose helps the unit run more efficiently. In the end he replaced my thermostat, cleaned the unit & added a hard start to the compressor all for less than $400.00. He did say that my unit is nearing the end of its life span, but said see how it runs this summer and if it's ok no hurry to replace. He is a respectful honest person who's not there to take advantage of you. He's really big into education & maintenance. It's obvious he really enjoys what he does. I highly recommend him!
