"We decided to take the leap and get some heat pumps installed by Seattle Heating & Cooling and do not regret the decision one bit. They are keeping our home super comfortable in every kind of weather -- hot, or humid, or chilly -- and reducing our energy costs. The team at Seattle Heating & Cooling was also great to work with, from their owner who did our estimate to the installers and the lady who coordinates everything when you call, they were super responsive and did a fantastic job."
"Wonderful shop, recommend most highly! The price was great; I asked for a quote for air conditioning and got a quote for a heat pump (ac + heat) that was less than I was told to expect for AC! Everyone I've told is astonished at the price."
"From the beginning when Serge came out to our home to give an estimate for a new furnace, to the installation by Viktor and Kyrylo, everything went smoothly. The office personal were also pleasant to talk to. Highly recommend this company."
