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.

Goodman 5 Ton System

Excellent value, customer sales support (a human called to confirm online order... greatly appreciated!), fast shipping. Very happy customer.

A + Company

Great price, communication and service I will be buying another furnace from them Fantastic !

Sale representative Lopez was very experienced and professional. I would recommend this company to any one and I am looking forward to work with Lopez again.
