Old ducts were leaking air everywhere. They replaced the entire system and our house cools evenly now. Noticed a significant drop in energy bills. Quality HVAC ductwork. (Denver)
Rita Y.
Old unit was on its last legs. They quoted us fairly, scheduled within the week, and had the new unit running by 3pm same day. Impressive HVAC efficiency. (Denver)

Other company said we needed a whole new system. These guys came out for a second opinion and found it just needed a new contactor. Saved us thousands. Honest HVAC repair. (Denver)

Thank you for the feedback! We are glad the experience was positive overall.

Our AC died during a heat wave and they had a tech out within two hours. Diagnosed a bad capacitor, replaced it on the spot, and we had cold air again. Lifesaver HVAC service. (Denver)

Referred by a coworker who had a great experience. Can confirm — Dalco Heating & Air Conditioning does quality work at a fair price. They were honest about what needed to be done and did not try to upsell me on things I did not need.
