HVAC in Colorado is heat first at altitude, with cooling and hail damage riding along on the Front Range. Furnaces and boilers have to burn correctly in thin air. A replacement copied from a sea-level habit can be the wrong fire. The high country and the Front Range both see long heating seasons. The western slope adds a hotter cooling season. Hail dents condensers and bends fins, and a storm can leave the cooling wounded while the heat is what you need the next morning. Freeze protection for condensate lines and for pipes near the air handler is not optional in a crawl space or an attic that drops below freezing.
Say heat or cooling, and say the town. No heat: does the furnace or boiler try. Ask whether the heat exchanger, the flue, and combustion air were part of the look. Ask whether the equipment is being sized for this house and this elevation, not matched only to the old label. Ducts in older brick houses leak and were sometimes an afterthought. Boilers and radiators are a different system from forced air. Do not let a visit assume the wrong one. Filters matter during winter inversions along the Front Range, when the house stays closed.
If hail hit, say whether the outdoor unit is dented, leaking, or merely noisy. Ask what gets ruled out before a compressor is condemned. A packed filter and a collapsed duct can imitate a major failure. Maintenance before the first hard freeze is the heating conversation. Maintenance before summer storms is the cooling conversation. If you have no heat now, the schedule is not the point.
Hail season and heating season overlap more than people admit. A dented condenser does not excuse a furnace that failed in the last cold snap. Say if both are hurt. Thin air is the other fact. Name the town so the fire is planned for this elevation, not for a catalog written at sea level.
Name the altitude in the only way that matters: the town, and whether the equipment already struggles to keep up. Call the number on this page.
