Frozen AC Coil Repair in Rochester, NH

Frozen AC coil repair in Rochester, NH begins with turning the cooling off. If you see ice on the copper line outside or frost on the indoor coil, running the AC longer only builds more ice and can send liquid refrigerant back to the compressor. Set the thermostat to OFF and the fan to ON to start the thaw.

A coil freezes when it gets too cold, and that happens for two main reasons. Low airflow is the first: a clogged filter, closed supply registers, a dirty evaporator coil or a weak blower motor lets the coil temperature drop below 32 degrees. Low refrigerant charge is the second, because a system that is short on refrigerant runs lower suction pressure and a colder coil.

Our crew checks both. We measure static pressure across the air handler, inspect the evaporator face for matted dust and pet hair, and put gauges on the system to read suction pressure and superheat. When the coil is dirty, we clean it with a non acid coil cleaner. When the charge is low, we go hunting for the (/services/refrigerant-leak-repair).

Melting ice also floods the drain pan, so we check the drain line too. Call (866) 703-1217.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about Frozen AC Coil Repair in Rochester, NH.

Talk to our crew
How often should I get an AC tune up?
Once a year, in spring, before the first long stretch of hot weather. In long cooling season states, some homeowners book a second check in late summer. A yearly AC tune up catches weak capacitors, pitted contactors and clogged drain lines while they are still cheap fixes.
What does SEER2 mean for my repair or replacement?
SEER2 is the efficiency rating used for new central AC equipment since January 2023. Minimums differ by region, with higher minimums in the South and Southwest than in the North. It does not change how we repair your current system, but it matters if you are weighing repair against a new unit.
How long does a central AC system usually last?
Many central air systems run 12 to 15 years with regular maintenance. Units near the coast, where salt air corrodes coils, and units in very long cooling seasons often wear out sooner. Age alone is not a reason to replace, but it factors into repair decisions.
What should I do before the technician arrives?
Check that the thermostat is set to COOL and below room temperature, check the breaker and the outdoor disconnect, and look at the filter. If there is ice, turn cooling off and run the fan. If there is a burning smell, shut the breaker off and leave it off.
Do you work on heat pumps and furnaces too?
Our focus is central air conditioning: split systems and packaged units, the outdoor condenser and the indoor coil and air handler. Call (866) 703-1217 and tell us what you have, and we'll let you know if it is a job for our crew.
