Short summers, hard on the parts that start it

Your air conditioner in Broomfield only has to run three months a year, June through August, and summer afternoons average 86 degrees. A unit that sits idle most of the year and then has to work hard as soon as the heat arrives puts real strain on the capacitor and contactor that get it started, and those are often the parts that give out first in the season's first real heat wave.

Broomfield has also seen 17 hail events and 60 damaging wind events over the past ten years, with hail up to 1.5 inches. Hail that size bends the thin aluminum fins on the outdoor coil, and bent fins block the airflow the unit needs to cool properly. You notice it as an air conditioner that runs longer than it should, or one that blows air but never quite cools the house the way it used to.

A new air conditioner would save little on running costs in Broomfield County, so the repair decision comes down to the unit's condition.

  • A new one at the federal minimum, 13.4 SEER2$280 a year
  • An older air conditioner$300 a year

Estimates for a typical Broomfield County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Colorado fuel prices and NOAA climate normals. Your home will differ.

Repair makes sense when a part like a capacitor or contactor has failed.

Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.

Why is my AC not blowing cold air?
The most common cause is a dirty air filter cutting off airflow, so check that first. A refrigerant leak, a failing compressor, or a frozen evaporator coil can also cause this, and none of those are things to diagnose yourself. If the air coming out is warm rather than weak, that points more toward the refrigerant side, and a contractor will need to check pressures to confirm it.
Why is my AC leaking water?
Water around your AC usually means the condensate drain line is clogged. Algae and dust build up inside that line over time and block the water from draining out, so it backs up and spills near the indoor unit instead. A frozen evaporator coil that later thaws can cause the same kind of puddling, so the fix depends on which one it is.
Why won't my AC turn on?
Start with the thermostat, since a dead battery or a setting knocked out of cooling mode will stop the whole system before it even tries. Next check the breaker, since a tripped one will keep the unit from getting power at all. If both of those check out and it still won't start, the problem is likely in the electrical or capacitor components inside the unit, and that calls for a contractor to test it safely.
