My request for an estimate was immediately answered and within a couple days Joe from BESCO Air was…read moreat the house to take a look. Once Joe spent about 45 minutes inspecting the 24 year old horizontal install, he had drawn a picture of what I had for his analysis. He described the issues and how to resolve them verbally before sitting down and drafting an estimate with 3 options for us to review. BESCO technicians Julio and Gio arrived with Joe 2 weeks later to get started. They reviewed the scope of work to demo and install this second floor attic project There was a lot of work to do and the install took the entire day. Julio and Gio stayed until everything was perfect. I have a Trane S9V2 60,000 BTU High Efficiency Furnace that replaced an oversized BTU furnace that would overheat in the winter and stop working. The Air Conditioner was replaced by the Bosch Inverter Ducted Split 2.0 Heat Pump. Both are high efficiency technology meant to save energy costs and perform quieter, faster, smarter. The quality of the install is key, no matter the various well known equipment brands to choose from. BESCO will provide professional and skilled teams to transform your HVAC systems worry free.

Update on July 17, 2026. It is nice of the owner, Mr James…read moreCox, to reply... James: your tech came and all he did (besides his constant: "call my office for a new unit") was spraying (my) water on my 2.5T Trane... THIS IS NOT "MAINTENANCE"... To say: "your system is on borrowed time to say the least and extremely inefficient the older it gets." is immature. the unit works FINE, is very efficient, as I write it. I am a seasoned Senior Design Engineer (has one USA patent granted) and know "something" about "something". I design things for all to use them and for some to service them. 2.5T for a small house like mine is possibly an overkill but that explains its lasting. 40 years of working AC unit is unheard of, correct, but it is ME who decides about replacement or maintenance, and your tech (still working there?) did NOT do the maintenance I've paid for. So, he did no technical work and you owe me that 99(?) bucks :-)

Both times, Vini came to evaluate my AC unit within 24 hours and ACTUALLY fixed it. It's hard to find a company that's this dependable and they've earned my trust.
