HIGHLY RECOMMENDED!!Our HVAC system broke so we had ASI and Bob Jensons Heating and Air come out to inspect the system and provide a quote. Both told us multiple things were broken and said that it needed to be replaced because it was an old commercial unit. They quoted $15K-20K to replace the system. Both seemed nice but used a lot of HVAC terminology and reassured us of their extensive knowledge and expertise, but they kept pressuring us to sign with them. I felt like they were trying to sell us a new vehicle with their negotiating tactics and their quotes were far too expensive. We accepted not having a HVAC system util Spring/Summer, leaving us without heat or AC but we decided to contact Dell-Mora Heating & AC. Within a few minutes after troubleshoot, Mike identified the issue with the AC portion but determined the unit would need to be replaced because the gas heating element was rotted. Mike recommend a new system that was far more affordable than the other contractors offered. We agreed on a contract, scheduled a tentative install date and he fixed the broken wire so the AC would work until the new system was installed.Now we are very comfortable with our new AHVAC system and with MUCH gratitude to Mike and his team. no high-tech HVAC talk to convince us and most of all, NO PRESSURE! He is honest, fair, efficient, and very knowledgeable of his trade profession. We will definitely be calling him for routine maintenance service!

Dell-Mora Heating and Air were top notch. Mike basically fixed what another company messed up and installed a new AC unit. Literally went out of his way to fix the furnace when he didnt have to. Mike was honest, super knowledgeable and never tried to upsell me on anything. You can tell Mike truly cares about his business and profession. Thank you!
