After 4 months of constant delays with another contractor and sloppy, substandard preliminary work, I contacted All-Temp for an estimate on installing a dual-zone mini-split. Chris came to the house and spent an hour checking all the rooms, taking measurements and looking at our electrical box. He produced a comprehensive estimate with every part and charge accounted for. Three days after I signed the contract with All-Temp, a team arrived first thing in the morning and had the heads and compressors installed by the afternoon. That included all the electrical work: wiring and AC junction box. They left no mess inside, and outside the compressor was on a new mat with all external lines insulated and covered. It looks great. They installed Gree, which is a great product with lots of features, quiet and powerful. Couldn't be happier. If you want a totally professional HVAC company with reasonable prices, go with All-Temp.
