I purchased an HVAC system from Green Street HVAC nearly three years ago for about $18,000--paying…read morealmost $10,000 more than an alternate (unlicensed) quote--only because I was assured parts and labor would be covered and the company would stand behind the install. During a cold front, I requested service (Ref: Estimate #20631848) and asked for basic documentation (contract copy, warranty registration, and a fully itemized estimate with OEM part numbers/MSRP and labor breakdown). The estimate came back over $3,000, with ~$1,700 just for the part, and included a line labeled "Band-Aid." After consulting Service, Inc. (Nashville) and Hiller, I learned "Band-Aid" can function as open-ended billing--i.e., "whatever it takes" after the part is installed, with no clear cap. To verify, I had Service, Inc. review the job. They confirmed in writing that:    *   The part is fully covered under the manufacturer's warranty ($0 to me), and    *   The install is about a 1-hour job, with a labor quote less than half of Green Street's total. In plain terms:    *   I paid a premium (~$18k), nearly $10k more than another bid, for peace of mind (parts + labor assurances).    *   Before a storm, I asked for help and transparency.    *   Green Street quoted $3,000+, including $1,700 for a warranty part that should be $0.    *   Their estimate used "Band-Aid," flagged by two licensed contractors as open-ended/uncapped language.    *   Service, Inc. honored the warranty ($0 part) and quoted a clear, fair price for ~1 hour of work. I support local businesses that do right by their customers--especially when families are relying on heat in bad weather. My experience with Green Street HVAC was unresponsive, non-transparent, and inconsistent with what was promised. If you're considering them, insist--in writing--on:    *   Proof of manufacturer warranty registration (model/serial + confirmation),    *   Written parts coverage terms (what's $0 under warranty), and    *   A fully itemized estimate (OEM part numbers, MSRP/list, exact labor hours & rate; avoid vague "Band-Aid" codes). Date of service request: 10/25 Estimate: #20631848 TL;DR: Green Street quoted $3,000+, including $1,700 for a warranty part and an open-ended "Band-Aid" line. Service, Inc. (Nashville) confirmed the part is $0 under warranty and the job is ~1 hour, at less than half of Green Street's total.

Nothing fancy; just clean and check the unit for the summer. That's when they came to my house and told me that my unit had over five problems, including leaking refrigerant, bad capacitors, electrical work, etc. Funny enough, their first quote was for 8k, which was to "fix these terrible problems." However, they gave me another crazier solution, to get a brand new unit, which was only 2 tons for a small house for 11k. Kid, you not. I went and got a second opinion, and as I suspected, my HVAC connections weren't the prettiest, but had no problems. The other HVAC professional also found out that they only cleaned a portion of the unit, so he installed a new disconnect, re-did my drain line, sealed my flashing, and rewashed my unit for $600 bucks. Do it at your own risk. I have never seen something like this, not even when I used to live in NY they tried to upcharge me like that.

Yesterday, the Heritage techs arrived to do the job. They did a quick system check and noticed freon was not low and like it should be if there was a true leak and I was told did not need to spend $3000.00 on a new coil unit !!! After further discussions, we identified that this Airbnb was having the coil freeze due to renters lowering the temperature to 50°. After a quick adjustment to all thermostats and only pay $128 I am so thankful for honest companies!! Highly recommend Heritage and this will be my go to company from now on!!!!

Their employees lack the training, skills, and company support to do their jobs. My system was recently completed and this morning it failed. The reason is it failed was it was not installed correctly. The owner will come on here and try and blame me for all the issues and you're free to figure out who's lying and who's telling the truth? And if you want to talk to me or see the horrific job they did please feel free to contact me. This company did a horrible job and has no clue what customer service means or customer satisfaction. Looks very much like they're going out of business so please do your diligence before signing a contract with Mainstream. Darryl Pater (owner of Mainstream) will respond to this and tell you this was all my fault. Believe who you will but his word is worthless and his moral compass seems broken. Frank Stewart is the only employee he has that is a man of his word and actually cares about the customer.
