A furnace built for a Boulder County winter
Winter nights here average 17°F from December through February, and your furnace runs from September through June. That is ten months of the year it needs to work, not just the coldest weeks. Summer afternoons average 78°F, mild enough that most of the load on a new system falls on the heating side.
Most homes here heat with gas, and whatever system goes in has to hold up to hard winters and the storms that come with them. Boulder County has seen 161 winter storms and 120 damaging wind events over the past ten years, and 13% of Colorado households lost power for at least 24 hours in 2024. A new furnace or heat pump needs to be sized and installed to keep working through what winter here actually does, not just the average night.

- When should I replace my HVAC system?
- Replace it when repairs stop making sense or the system can't keep up anymore. If your furnace needs a major repair and it's already old, or you're calling for service every winter, that's your sign. In Boulder, the furnace runs from September through June, so a unit that struggles here is putting in a lot of hours. Rising bills, uneven heat between rooms, and a furnace that runs constantly are also signs the equipment is wearing out rather than just having an off day.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it usually makes sense to do them together. A furnace and AC installed at the same time are matched to work as one system, and a contractor only has to open up your ductwork and electrical once. That said, Boulder homes need cooling far less than heat, so if your air conditioner is newer than your furnace, there's less reason to rush it. A contractor can look at the age and condition of each unit and tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace and or air conditioner in place, and connects it to your ductwork, gas line, electrical, and if there's an AC, the refrigerant lines. They test the system once it's running, checking airflow, gas pressure, and that it cycles on and off correctly. On a furnace, they'll also check the venting, since exhaust has to clear the house safely. Depending on the job, they may need to adjust ductwork or add a new thermostat to match the new equipment.
