Lakewood summers keep your AC working, and hail puts it at risk

Summer afternoons here average 80°F, and your air conditioner is the only thing standing between that heat and your living room. It runs hard for it. The condenser fan and compressor outside cycle on and off all day to keep up, and that steady work is what eventually wears them down.

Jefferson County has also seen 152 hail events over the past ten years, with stones up to 2.75 inches. That size hail can bend the thin aluminum fins on your outdoor unit's coil, or dent the fan and housing enough to throw it off balance. The 114 damaging wind events in that same stretch can rock the unit on its pad or send debris into it. If your AC is suddenly noisy, blowing weaker than it used to, or not cooling like it did last summer, a look at the outdoor unit is where that usually starts.

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

  • A new one at the federal minimum, 13.4 SEER2$90 a year
  • An older air conditioner$100 a year

Estimates for a typical Jefferson 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 choking off airflow across the coil, which can cause it to freeze up and stop cooling. Low refrigerant from a leak is another common reason, and that only gets fixed by finding and sealing the leak, not by just adding more refrigerant. If the outdoor unit is running but the air inside stays warm, a contractor needs to check the coil, the refrigerant charge, and the compressor itself.
Why is my AC leaking water?
Most of the time this means the condensate drain line is clogged, so the water that normally drains away backs up and finds another way out. It can also mean the coil has frozen and is now melting, which usually points back to a dirty filter or restricted airflow. Either way, water near your indoor unit means something in that drainage path needs a look before it damages the floor or ceiling around it.
Why won't my AC turn on?
Start with the thermostat. Check that it has power, is set to cool, and the temperature is actually below the room temperature. If the thermostat looks fine, the next place to check is the breaker for the outdoor unit, since a tripped breaker will shut the whole system down. If power is reaching the unit and it still won't start, the capacitor or the contactor inside the outdoor unit may have failed, and that's a job for a contractor to diagnose.
