    Covenant Heating & Cooling - The work I did to fix it

    Covenant Heating & Cooling

    (37 reviews)

    Would not recommend. I had a 3 ton AC unit installed. They replaced my old unit with a new one in…read morea different location that was convenient for them. This meant not putting the unit further back in the crawl space but right in the way of my crawl space entrance. This also meant installing a new pad that sits beside my already large and accommodating pad for the units, which also blocks a sprinkler head. The pump/drain installed was put right next to the house so water would drain between the foundation of my house and the pad. That also created a lot of algae buildup. I fixed this myself. Does the unit blow cold air, yes. Is this quality work? Not in the slightest. Despite this experience I called this company out to have my air ducts looked at for potential cleaning. A recommendation was made to have my air ducts cleaned. The quote received referenced systems being cleaned. It was NOT clear when they first came out they would only be doing 1 of 2 systems. I learned this while the work was being done. I reached out to express my frustration that a $1200 duct cleaning was only for 1 of the 2 systems. I received a call back with the technician citing he only looked at one system. The technicians explanation and the quote did not make it clear that only 1 system would be cleaned. Strange too that the odor that triggered this duct cleaning was on the system they installed. I had no issues with the original system that was there for 13 years. I will not only NOT recommend this company, I'll go out of my way to warn others. There are plenty of companies looking to earn peoples business, and I'm glad to give it to them.

    We had an A/C issue and our normal company couldn't make it out so we called Covenant. We have used…read morethem for seasonal maintenance but nothing else. Trip charge was $109 to basically tell us to turn it off and they would be back the next day. Said he couldn't charge the gas because it would just run out. Night of heavy sweating. As they said, they came out the next day and analyzed the issue. $300 for leak detection. Once they found it we were told, even under warranty, it would be $2100. I do not like to get one opinion so I called our normal company. They came right out, found the leak without $300 leak detection and said it would be $800 out the door. In addition he charged it and said it would last us a week and call if we needed him before then. I do give credit to Covenant for coming out but charging us 3 times as much was ridiculous.
