They genuinely enjoyed chatting with him, which you don't hear every day! As a landlord, I really appreciated them keeping us in the loop throughout the process, it made everything so much easier on our end. It's such a relief knowing our tenant was taken care of and treated well. We'd definitely use them again.

I chose Mid-South HVAC & Electrical after reaching out to seven different companies for quotes to…read morereplace my AC and furnace. Cameron responded to my initial inquiry promptly and provided a formal quote that stood out from the rest. Getting quotes from contractors in Tennessee can be a challenge, but Mid-South made the process straightforward. Their prices were reasonable, and Cameron answered all my questions thoroughly and promptly, so we decided to move forward with the work. I do have to mention that the day before the replacement, one of the crew members came by to inspect the ductwork, which required climbing through my attic. Unfortunately, during that process, he accidentally stepped through the ceiling, creating an 18-inch hole. This incident added a lot of extra work to the project, but Cameron, although not always the most timely communicator, took responsibility. He sourced and paid for the repairs, which included repainting the ceiling and an adjacent wall. I imagine it was an expensive mistake for him and his team. Even though I'll have to hire someone out of pocket to fix the lumpy drywall after two unsuccessful attempts from two different contractors, I'm still giving Mid-South HVAC & Electrical 5 stars, for now. The crew worked efficiently to replace the units, all while respecting our shoeless house policy, which I'm sure was inconvenient for them. The new AC is holding up well through the recent 99-degree heat, and we'll see how the furnace performs this winter. We also have a 1-year labor warranty, which I hope we won't need to use.

I was actually uncertain about using a company that had so few reviews, but they were listed as a…read morewarranty partner with my brand of furnace. I looked up their website and their website is near identical to A-1 Heating & Cooling - which had me concerned, concerned that they were owned by the same people. If that is the case, I couldn't tell because the lady who answered the phone her mannerism and approach is a lot more down to earth and personable - in a way Southern. I explained to her the situation about me looking for a second quote and my HVAC being under warranty - she wrote a few things down and told me she would call me back. She called me back minutes later and stated that someone could come out there within the next hour as they are finishing up a job near me to assess. I was surprised to hear same day service and it was already 11AM. Before he even came out - she even gave me the total labor cost to install it - if the item I needed to have replaced was the correct one. I called numerous places, and none of them would give me any type of quote over the phone. Other places told me everything from 'No one is here to do that' to 'We would need someone out there before you receive any quote since it's a repair.' I feel like she has some authority when it comes to the business, and that is always a plus. But, he came out there less than an hour later, diagnosed it, ordered parts from Nashville, and showed up the next morning to install it. Didn't try any pressuring sales tactics to upsell me any type of warranty or maintenance plan. The only thing they should get is one of those Square devices, so that they can take debit/credit cards via phone/tablets instead of over the phone.

The lost art of honest, customer service, has been revived by Eric and his professional team. I…read moreHIGHLY recommend Optimum Heating & Cooling for your HVAC needs because of the honest customer service and the detailed maintenance that is offered. It is my honor to support a Veteran owned business because of the sacrifice and the selfless decision to serve in the military. Thank you for your service. 1. I woke up to a puddle in my basement 2 months ago. I am part of a monthly club with a different HVAC company, it includes service to my HVAV unit and discount on maintenance calls. The company installed a shut off valve for 350.00. They also performed the annual service on my HVAC unit at that time. (Make sure you ask specifically what the company does during annual maintenance. Ask to look at the outside unit when it is uncovered, ensure that it was cleaned. When they are done, confirm they did all that they are required for the service you pay for. Even check YouTube to learn the components of the HVAC unit- all things I did NOT do initially) 2. Less than 2 months later I make another service appointment because the AC is blowing hot air, a different technician arrives and says I have a leak in my coils and recharges my unit with a pound of R22 for 300.00. He explains that if the coolant leaks out the cold air would be temporary. The technician recommends replacing my unit because it is 17 years old. The next day the AC is blowing hot air, the company sends a different technician out, he recommends I replace my unit and gives me a rough estimate of 12k. (Do not feel pressure from the technicians, sales or the company, take a day to think about it and to do some home work and research) 4. I decide to get a second opinion. The Next company explained that the fan was not turning and my motor would need to be replaced, The technician explained that my unit is 17 years old so replacing the motor and coils and to fill up with R22 will be costly, so the overall recommendation is to replace the HVAC unit. More information so I say let me call another company to see if there is consistency in the diagnosis. 5. I checked out Home Depot to see how much an actual unit cost to install, Home Depot subcontracts with a different HVAC company. The sales person comes to my house and quotes us 13,000 as a 60 day price and 9,000 if I pay and schedule today. While at Lowes I see an advertisement on someone's work trailer for a HVAC contractor, they provided an estimate but did not inspect the unit. 7. While deciding which company we would hire, someone I was speaking to recommended Optimum Heating & Cooling. He explains that prior to him hiring Optimum, he paid a contractor 4k upfront to start the work on his HVAC project, and they never completed the work. (Money upfront may be risky, so proceed with caution if you make that decision) The 4k loss that he shared was quickly overshadowed by the gleaming review and recommendation to call and hire Optimum Heating & Cooling. 8. Optimum's scheduling department was very responsive. When Eric arrived, he spent so much time explaining things in detail, by now I understand the lingo because I learned about the HVAC unit online. The next day we received an estimate on the repairs. 9. My family and I have been in a hotel for 3 nights due to the heat wave (If you do not have to rush on the decision- take a minute and do your research). When Eric realized my family was in a hotel, he was very kind to offer 2 loaner window units until the work was complete and to help us save money. I of course was grateful because I canceled the remainder days of the hotel reservation. 10. Eric and his team headed over to start the work, after about 20 minutes Eric comes in my home and says your unit is actually maintains coolant, we will monitor the levels, the next update was the fan is not moving, your motor may be bad, the last update, which was music to my ears- with CAPACITOR- in hand, Eric explains that this is the issue. When they replaced your capacitor, the motor began working and the 17 year old AC unit was operating at full capacity. 11. So to recap to the most important part of the experience. I agreed to a full HVAC replacement with Optimum Heating & Cooling, they started working on my AC unit, it was determined the fix was replacing the Capacitor, which cost under 200.00. So instead of taking the big payday and replacing the HVAC unit, they explained that they pride themselves on honest business practices and sound technical maintenance. 12. Contact Optimum Heating & Cooling for your questions, maintenance, service, install, or if you just want to meet a solid military veteran and have great customer service from his wife when you call.
