Denver homeowners, in their words

4.9 / 5 · 1,137 reviews

"Furnace quit at 11 pm when it was 9 degrees out. Kelvin had a tech at our door by 8:40 the next morning and heat back on before lunch."
Dana WhitcombAurora
"He showed me the thermal camera on my phone. The cold spot above the kids room was a crushed duct in the attic. Fixed in an hour."
Ruben EstradaLakewood
"Quote at the table, install the next Tuesday, invoice matched to the dollar. The new heat pump handled that week of single digits."
Meg OduyaEnglewood
"Our upstairs was always 7 or 8 degrees hotter in July. After the duct balancing it is within 2. I did not think that was possible."
Tom HalvorsenArvada
"Booties on, dropcloth down, walked me through what failed. Fair price and no upsell on a new system we did not need."
