Thank you . The service people (all of them) have kept my 25+ year unit chugging along for many years. They do annual maintenance work, major system installation and everything in-between correctly and reasonably priced. Better yet, the service people are polite, never aggressive. They will always explain the problem and show you the damage by picture or the actual part which means a lot to an old lady (with no mechanical ability). Oh, as far as my old unit, I am getting them to install a new one soon.

Had a 2nd opinion come out and ask me who was messing around with the fan because it was hooked up in reverse. The 2nd opinion tech was able to get the unit working at the service call without the freon they told me I needed or new condenser fan. Also important to note, there would have been no way for the unit to have been operational two full summers) with the fan in reverse, leaving the only people to have reversed the fan direction being J&J. When presented with this information, J&J became defensive and instead of apologizing, refused to come out and fill up the freon on the other unit. If they weren't so defensive, I'd be more inclined to give them the benefit of the doubt. They instead chose to get ugly with me leading me to believe I had uncovered their scam. Again, proceed with caution. Attached is the bid with the condenser fan that wasn't needed and supporting text from my tenant who as also told our problem was the fan going the wrong direction.

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.

The man then arrived and was apparently new, yet trying to diagnose this alone. After being in his car for 45 minutes with no update, he finally said I would get it fixed 4 days later and the diagnoses was one they had said before (that was also wrong then). It was wrong again this time. I called another company, they came out the following day and it was fixed in a day. Will never recommend MJ Frick and their incompetency.

Was told I would receive a callback and a quote on a part out of warranty, or replacement cost for new unit. The repair technician gave the wrong diagnosis regarding where the leak was. The company that came and repaired my unit gave an entirely different diagnosis and it was on the outside two pipes the company had to solder where the Freon was leaking from. Amazing the difference in trying to save the customer unnecessary money on new units when your unit is 12 years old and out of Warranty. Very disappointed in this company and will never use them again.

I called them for a repair and my husband told them it needed the gas. So they come out and tells us yes it needs gas! But get this they say we don't put the gas in anymore! They purposely withheld that information from us just so they could charge for a service call knowing fully well they couldn't perform the service needed. I have now decided to file a BBB report . I will be looking for a new service company. I had been paying $ 119.00 a year for Spring and Fall check ups. Not bad very reasonable. My husband called and was told the plan was 100 a year. Then why am I paying 119.00? I called up and to inquire about the rates and was told they do not offer the yearly maintenance plans anymore. Well how can that be if not 5 minutes before they gave my husband a quote for a 100.00. I do not like dishonest companies. I thought so highly of this company for a long time. Nothing good lasts I guess. Very disappointed. I have never heard of an AC Company not having a yearly plan. They also said we needed another capacitor at 150.00. The one they put in didn't even last 5 years, and they should last from 5-20. I had asked for a refund of the 99 dollar fake service call and was denied so therefore I did not let them put this in. We bought one from Amazon for less 20 bucks. Big mark up.

With temperatures around 90 degrees outside, we needed someone to help as quickly as possible. I called a couple of the larger HVAC companies for emergency service, but they all told me it would be the next day before they could come out. Then I called Highlands Cooling. Cody was already on his way to an appointment in Clarksville (I live in Nashville), but he told me he'd come by afterward and guaranteed we'd have air conditioning that night. He kept me updated the entire time, arrived when he said he would, quickly diagnosed and fixed the problem, and got our AC running again. Just as promised, my wife, our newborn, and I had cool air that night. And did it for a very fair price! I can't thank Cody and Highlands Cooling enough for coming through when we needed them most. I highly recommend them to anyone looking for honest, reliable, and responsive HVAC service.
