Best HVAC System Repair in Nashville TN

My furnace was blowing cold air instead of heat. I paid a company to come out to service. This local,commercial company tried to convince me to purchase a new furnace.  Me
knowing my furnace
was repairable, I decided to get a 2nd opinion.  I was then referred to NEI. I contacted Damion. He seemed very nice and professional. I had to wait a few days for him to come out to do a diagnostic check. But I trusted the person who referred me, so I was patient and greatful when Damion finally arrived. He seemed very  nice, professional and knowledgeable. He also told me he was one of the owners... So I was happy and willing to work with him. Within a few days, my unit was working!!! Hallelujah!!! I paid him without delay. He made sure to mention that he gave me a good price due to our mutual acquaintance..... several times. I thought this was rather tacky...but whatever.  I finally had heat. The next day, my furnace started making a weird noise and wasn't performing optimally. I called him and he told me he would work me in to check out the issue. I waited patiently several days.
Well, everytime I called, I received an excuse why he didn't/couldn't make it. I waited 2 weeks!! I finally grew impatient.
Started to feel I was getting the run around. I called again....tried to explain my dissatisfaction. He basically told me to call another company, and then hung up on me.   He refused to answer any of my calls, or return text. I sent an email to the company and everything! All I wanted, was a scheduled day he would return, not to be worked in as a standby with unpredictable days/time.
Once paid, my issue was no longer a concern. Customer service at it's finest!! He did not honor his work. Now, I will have to trust and pay another company....my 3rd ....to come out to do ANOTHER  diagnostic check on my furnace! I am very unhappy!! My hard money wasted!!

Rusty and Josh were both onsite for my hvac replacement.  Both are extremely friendly and knowledgeable and not afraid to share that knowledge should you ask for detailed explanations. These guys are the epitome of service.

Our furnace was in a tight and difficult position and they worked it out flawlessly.  You get all this and fair pricing.  They've made a customer for life out of us.

Helton's was wonderful when my furnace broke. I called in the morning because I smelled gas and David was at my house by the afternoon to check it out. He was extremely prompt with responding and showed up just when he said he would. As it turns out I needed my whole HVAC system replaced, which is any homeowner's nightmare, but David and his team made the process as easy as possible. Can't recommend this company enough. They are good people who do quality work!

David did a great job installing gas lines under our house and a new sink and faucet. He was always here on time, reasonable rates

I don't get it. If for whatever reason a business doesn't want your business, then why can't they just say so? In stead of saying that they'll call you back and then just blowing you off. Kimbro, please know that this sort of business practice is very unprofessional, disrespectful, and plain rude.
