Client Reviews

I’ve been a customer for over 10 years and have always valued this company for its quality work and transparency. Unfortunately, my recent experience was very disappointing. I called for an after-hours weekend HVAC issue and was quoted $140 for the service visit and $210/hour. The technician was at my home for less than an hour, but I was charged $770 due to a three-hour minimum that was never disclosed when I authorized the service. Had I known about the minimum, I would not have agreed to the call. After more than a decade as a customer, I’m extremely disappointed to feel this pricing was not transparent. I will be taking my business elsewhere. If you use this company for emergency service, I strongly recommend confirming all minimum charges and total potential costs before authorizing the visit. Update: Unfortunately, my concerns have only continued. The invoices were not provided until I requested them five days later. I have now had three separate conversations attempting to resolve the issue and was told a billing error occurred and I had been charged plumbing rates. The information provided in each conversation has been inconsistent and, at times, misleading. The original fees I was quoted were repeated to me, yet the charges and explanation continued to change. It appears that Brandon, Barry, and Sabrina each have different information regarding rates, minimum charges, and how this matter should be resolved. As of 8/14/26, this issue remains unresolved. After more than 10 years as a customer, I am extremely disappointed by the lack of transparency, consistency, and accountability throughout this process. I would strongly recommend considering another company, particularly for emergency service, where clear pricing and communication are especially important.

A small leak at the water softener shut off value...3k later I'm quoted for a whole system replacement including water softener and expansion on the water heater. Then I call to go over the quotes and the person on the other end was annoyed I was confused. Unfortunately I do not reside in that residence so I do not know what is going on and why i have such a massive quote and the person was rude so I hung up. There are hundreds of other places i will spend my money but NOT here. Will not be recommending this place to a soul.

Called Total Group today, had the quickest response time I’ve ever had. I’m under an hour we were back up and running. Sean was fast, friendly, polite, and even fixed some of the work a different Nashville company messed up.

Holiday weekend and the HVAC stopped working. I placed a call to Total Group for help. Received a callback from Jason [on duty tech]. As it was late afternoon [and the weather was pleasant], I was okay with Jason coming out Sunday morning. Jason arrived on time [as always], inspected the unit and fortunately was able to make the repairs immediately. He had the unit cooling within 15 minutes of his arrival time. He stayed to ensure no other issues. Jason is an excellent service technician....ALWAYS on time, professional and friendly. If you're looking for a company who hires the best, look no further than Total Group. Thank you Total Group and Jason for exceptional service.

11-29-23 update: another semi annual preventative maintenance service to my unit. The technician Tim was punctual, professional, knowledgeable and courteous. Highly recommend this company. Also, preventative maintenance is cheaper than repairs. Their twice annual service is a great value for the money. UPDATE to original review: 1/2021 I had second annual preventative maintenance check. Communication with Total Group is outstanding! Received a text from Kassandra reminding me of my appointment and confirming the time. Eric, the tech, was prompt, professional and very proficient. Total Group continues to provides consistent excellent customer service. 7/2020 Total Group has provided me with outstanding service for years. Because I am a member of the Total Care Club, Much thanks to the technician. It is so refreshing to work with a locally owned small business that provides excellent customer care!!

Avoid this company for installs. I engaged them in May 2022 to install a new hvac unit. They initially sent third party contractors who did not complete the job. An employee then came out and could not complete the job timely either, causing my family to have to stay with relatives for a night. To this employee's credit, he at least provided a window unit for me to sleep next to overnight. After the unit was actually operating, it was not working appropriately. I had to withhold payment from this company for several months before someone came out to make it right. Fast forward 15 months, I just discovered they installed a box that is too small for the unit (see attached picture) and used tape to try to cover about a 4 inch gap. This tape melted and came loose causing several air leaks. I was told I was losing about 2 vents' worth of air due to these leaks for who knows how long...on a 1 year old system.

I had natural gas shut-off valve (outside furnace) that had slight leaks. I texted the photo to the Total company before I made the appointment. The technician came on August 30, 2022. I want to give 3 feedbacks: (1) Overpriced: The technician put sealant outside on the top of the shut-off valve. Charged $224, including a diagnostic fee of $89 and a service fee of $135, while the actual work took a few minutes. The technician insisted that was their company’s policy. (2) Poor quality: the shut-off valve never stops leaking. See photos for details. (3) Poor customer service: I contacted their customer service. They could make another appointment but would charge the same diagnostic fee of $89 plus whatever applicable. I don’t want to pay the same problem twice. So, I’m finding a different company now. In the meantime, I’m disputing this transaction with my credit card company now for the reason of not meeting my expectation. This is the first time I ever disputed a credit card transaction after using credit cards for more than 20 years.
