Three months to do all the work

Your air conditioner in Waterbury gets three months of real work, June through August, with summer afternoons averaging 82°F. That is not extreme heat, but it is steady, and the system has to hold up through every one of those afternoons.

When a capacitor or contactor is already weak, this is the stretch that finds it. You notice it as a system that struggles to start, or one that runs but never quite brings the house down to temperature on the warmer afternoons.

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

  • A new one at the federal minimum, 13.4 SEER2$330 a year
  • An older air conditioner$350 a year

Estimates for a typical Waterbury home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Connecticut 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.

Connecticut requires HVAC contractors to hold a state license.

The license comes from the Department of Consumer Protection. It belongs to the contractor, not to any single job on your air conditioner.

On a repair like this, the part that matters most is the refrigerant line. Any technician who opens that side of your system has to hold EPA Section 608 certification, no matter what state they work in. So on this job, the contractor's state license and the technician's federal certification are both in play, and each one covers a different part of what happens.

Why is my AC not blowing cold air?
The most common cause is a dirty air filter choking off airflow, so check that first. A low refrigerant charge from a leak will also do this, and it won't fix itself since these systems don't use up refrigerant over time. If the outdoor unit isn't running while the indoor fan blows, the compressor or a capacitor may have failed, and that needs a licensed contractor to test.
Why is my AC leaking water?
Most of the time this is a clogged condensate drain line, and the water is backing up instead of draining outside. It can also mean the coil has frozen and is now thawing, often because airflow is restricted by a dirty filter. A cracked drain pan will leak too, and that part usually has to be replaced rather than repaired.
Why won't my AC turn on?
Start with the thermostat. Check that it's set to cool, the temperature is below room temperature, and it has power, since dead batteries are a common cause. If the thermostat looks fine, check the breaker for the outdoor unit, since a tripped breaker will shut the whole system down. If the breaker keeps tripping once you reset it, stop and have a licensed contractor look at it rather than resetting it again.
