Grand Junction asks a lot of a heating and cooling system
Winter nights here average 18°F from December through February. A new furnace has to bring the house back up to temperature on nights like that, again and again, from September through May. That is nine months of the year on heat alone.
Summer asks less of the system, just July and August, with afternoons averaging 83°F. Between the two seasons, a system here runs eleven months out of the year, one job or the other. Most homes in the area heat with gas, so the furnace carries most of that load. Whatever goes in should be sized for both jobs, not just the one that runs longer.

- When should I replace my HVAC system?
- Replace your furnace or air conditioner when repairs get frequent, the equipment struggles to keep up, or a major part fails on an older unit. A cracked heat exchanger or a failed compressor on equipment that has already needed other repairs is usually the point where replacement makes more sense than fixing it again. Homes here run the furnace from September through May, so it does far more work over a year than the air conditioner, which only runs in July and August, and that heavier use tends to show up as wear first. Rising bills, rooms that never quite reach temperature, and repairs that keep coming back are all signs worth having a contractor look at.
- Should I replace my furnace and air conditioner at the same time?
- If both are old and showing problems, replacing them together often makes sense since they are matched to run as one system. A furnace and air conditioner typically share the same blower and ductwork, so new equipment sized to work together tends to perform better than pairing a new unit with an old one. If only one has failed, a contractor can tell you whether the other has enough life left to wait or whether mismatched equipment will cause problems now. Since homes here need heat from September through May and cooling only in July and August, the furnace carries the heavier load over the year and often reaches the end of its life first.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace, air conditioner, or both in place, and connects it to the ductwork, gas line, and electrical or refrigerant lines. The furnace gets tied into the vent for exhaust, the outdoor unit gets connected to the indoor coil, and the system gets tested for airflow, temperature rise, and refrigerant charge before the job is called done. A contractor will also check that the existing ductwork is sized right for the new equipment, since ducts that worked fine with the old unit do not always suit a new one. The exact steps and how long the job takes depend on the house and the equipment going in, which a contractor can walk you through for your situation.
