Eight months of heat, three of cooling, almost no rest in between
Your furnace in Aurora runs from October through May. On winter nights that average 16°F, it cycles on and off for hours to hold the house steady, and every one of those starts puts wear on the igniter and the ignition control board. When one of those fails, the burner won't light and the house goes cold on the coldest nights of the year.
Then summer afternoons push past 86°F and the air conditioner takes over for June through August, often after sitting unused since spring. A compressor or capacitor that was already weak tends to give out right in that first real heat wave. Between the two seasons, this system gets almost no rest, and Arapahoe County sees its share of winter storms and damaging wind, the kind of weather that also knocks out power and can leave a furnace or heat pump needing a reset before it will run again.

A new furnace and air conditioner would cut about $120 a year off heating and cooling for a typical Arapahoe County home.

Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
- Why is my heat not working?
- Most often it is the thermostat, the igniter, or a safety switch that shut the furnace down. Check that the thermostat is set to heat and the temperature is above room temperature, and check that the filter isn't so clogged it choked off airflow. If the furnace runs but never lights, or lights and then shuts off again, that points to the igniter or the flame sensor, and a contractor will need to test those. At 16°F on a winter night, this isn't something to leave for later.
- Why is my system running but not cooling the house?
- If the blower is moving air but the air isn't cold, the problem is usually with the refrigerant side, not the fan. A dirty filter can also do this, since it blocks airflow across the coil and the coil can freeze up as a result. Check the filter first. If it's clean and the air still isn't cold, the system needs a contractor to check the refrigerant charge and the coil.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set to the mode you want, heat or cool, and that the temperature setting is actually calling for the system to run. Check the filter next and replace it if it's dirty, since a clogged filter causes problems in both winter and summer. Check that the breaker for the system hasn't tripped, and for a furnace, make sure the switch that looks like a light switch near the unit is turned on. If the system still isn't working after that, a contractor will need to look at it directly.
