AC Repair

A repair visit starts with questions, not with a parts list. When did the cooling drop off, does the outdoor unit run at all, is the second floor warmer than the first, when was the filter last changed. The answers narrow things down before a gauge ever touches a service port. From there the diagnosis is measurement based.

We check static pressure across the air handler, verify airflow, read superheat and subcool to see what the refrigerant charge is actually doing, test capacitors and contactors under load, and confirm the condensate path drains properly. On older equipment we look hard at electrical connections, because years of heat cycling in an unconditioned attic or garage loosens lugs and burns terminals.

If the fault is a run capacitor or a clogged drain line, we say so and fix it that day. If the compressor is dead in a twenty year old R-22 system, we say that too, and we lay out honestly what repair costs against what replacement costs. Integrity and honesty are the values Yosef built the company on, and most often they show up in what we tell you not to spend money on.

No-cooling calls in this area tend to fall into a handful of families. Electrical failures come first: run capacitors, contactors, blown fuses in the disconnect, failed condenser fan motors and blower motors, and control boards that gave up after a power event. Airflow problems are next, and they get blamed on refrigerant far too often.

A collapsed flex duct, a crushed return in a finished basement, a filter nobody has changed since spring, or a frozen evaporator coil all read like a refrigerant problem to the homeowner and are not. Then there are genuine refrigerant issues: a leaking evaporator coil, a corroded line set, a low charge that someone topped off last year without ever finding the leak.

Water is its own category, and in humid Maryland summers a plugged condensate drain or a dead pump can put water on a finished ceiling fast. Older R-22 systems introduce a real decision, since that refrigerant is no longer produced and replacement equipment now ships on R-410A or the newer R-454B. When repair stops making financial sense, we say so and talk through replacement, financing and the $150 off new system installation offer.

We give you an arrival window and call ahead. The technician arrives in a marked vehicle, protects floors on the way to the equipment, and starts by looking at the whole system rather than the one part you suspect. Expect to be asked questions, and expect to be shown what was found: a burned contactor, a reading on the gauges, a filter that has turned gray.

Nothing gets replaced before you approve the price. Common parts such as capacitors, contactors, fuses, float switches and universal motors are usually handled on the first visit. A specialty part, a coil or an OEM control board may need to be ordered, and if so we tell you the timeline instead of leaving you guessing. Military members and seniors get 10 percent off any HVAC repair, and the work is backed by our 100 percent satisfaction guarantee. Regular hours run Monday through Friday 7:30 AM to 7 PM and Saturday 9 AM to 4 PM, with 24-hour emergency service outside of that.

Warranty coverage

Two separate warranties usually apply to a repair. The first belongs to the part itself and comes from the manufacturer, and its length depends on the brand, the part and in many cases on whether the original equipment was registered after installation. The second covers our labor. We stand behind the work we perform and back it with our 100 percent satisfaction guarantee, and the specific term for your repair is stated in writing on the invoice rather than implied here.

Ask for it, keep it with your equipment records, and hold onto the model and serial numbers. As a Carrier authorized company we can look up factory warranty status on Carrier equipment directly. Work is performed under Maryland HVACR license MD70918. We are NATE certified, an ACCA member, and BBB accredited with an A+ rating.

Available incentives

Repairs themselves are rarely rebate eligible, and we would rather tell you that than imply otherwise. Utility and federal money is aimed at replacement equipment and efficiency work, not at fixing a failed capacitor. Where it does matter is the moment a repair stops making sense.

Home Comfort Air Services participates in the Pepco and BGE residential rebate programs, which run under Maryland EmPOWER and cover qualifying high efficiency cooling equipment, heat pumps and related upgrades for customers in those service territories. Most of Montgomery and Prince George's County sits in Pepco territory, with BGE serving parts of the area to the north and east. The federal Section 25C credit that used to apply to this equipment ended for anything placed in service after December 31, 2025. Eligibility, efficiency thresholds and available amounts change from year to year, so we check current program terms before you commit to anything.
