Great service.

Great service and very fast Shipping

As advertised and fast delivery!!

My interface with HVACStore was very good.

My transaction with the HVACStore was very good. It deserved a 5 star but I dinged it one star because the freight company did not deliver my new packaged unit on December 11th as they had communicated to me they would. They finally delivered at 3 PM the next day, December 12th. I and my installer had driven to Raleigh, NC (115 miles) on December 10th expecting the installation to start the next day. We were able to get the unit set in place the afternoon of the delivery but noting more that day. The following day we were able to install the unit and make it fully functional, but we did not have time to install an enclosure around the opening of the house crawl space where the ducts passed through. My installer left Raleigh very early on the morning of the 14th and is no longer available to do this enclosure. I will have to return to Raleigh for this remaining work which would have been already done had the HVAC unit been delivered as originally scheduled.

20-year-old 14 ton Goodman condenser

I have a 20 year-old Goodman 4 ton condenser and furnace. It was the best investment I ever made reasonable in price and minor repairs of normal failures. My plan if this one goes to have one shipped identical to what I own and try to find a local installation company.

Happy with the product and shipping.

Impressed by the quality

I’ve installed Goodman heat pumps before at a similar price point. This was better quality, and a great deal from the HVAC store. I’m always a little nervous about picking the lowest cost provider but the came through quick and no damage.

I’m in the middle of install so if you don’t see an update, things went well. As I said, first impressions as I opened it up to adjust airflow direction was very impressed!

A good store to shop for HVAC supply

The store did some things I didn't believe the manager was very helpful in fixing my problem

Perfect

Great communication and great price

very reliable company and great prices

Bought a few units from this company and they were very friendly and easy to work with. Either matched prices or beat the price and had fast shipping also.

Excellent company to purchase from

I wasn’t to sure about if this company could deliver it quickly but it arrived within a week. No issues. I needed this one for parts as my first one that I installed a year ago had the ecm go out on the blower fan. Parts are hard to come by for this Chinese brand. I think the ecm went out due to condensation in the main supply plenum dripping onto fan motor. I do like this ac unit but hope the fan lasts longer than a year. I covered the fan ecm with flex seal tape.
