Weld County asks a new system to work almost all year
Winter nights here average 16°F, and homes need heat from October through May, eight months of the year. Add the three months of summer cooling, June through August with afternoons near 86°F, and a heating and cooling system in Weld County is working eleven months out of the year. A new install has to be sized right for both jobs, not just one.
Most homes here heat with gas, and a new furnace has to meet the federal efficiency minimum. Weld County has also logged 172 damaging wind events and 42 winter storms over the past ten years. An outdoor unit needs to be set and connected to take that kind of weather without losing power or coming loose.

- When should I replace my HVAC system?
- Once your furnace or air conditioner needs frequent repairs, or a repair quote starts to rival what a new system costs, it's time to consider replacement. Watch for rooms that won't heat evenly or a furnace that runs longer than it used to. Homes here need heat from October through May, so your furnace carries most of the load over 8 months a year. If it's older and you're calling for repairs more than once a season, have a contractor look at replacement instead of another fix.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, it usually makes sense to replace them together. A furnace and air conditioner installed at the same time are matched to work with each other, and a contractor can open up your ductwork and electrical once to handle both. If one unit is much newer than the other, there's no reason to replace something that still has years left in it. A contractor can check the age and condition of each and tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, then sets the new equipment in place and connects it to your ductwork, gas line, electrical, and refrigerant lines. Once everything is connected, they test the system, check refrigerant levels, and confirm the thermostat is talking to the new equipment correctly. On a gas furnace, they also check the venting to make sure exhaust is leaving the house properly. The exact steps depend on what you're replacing and how your current setup is built, so a contractor can walk you through what it will involve for your house.
