AC Repair in Germantown, Gaithersburg and Rockville, MD
When your air conditioner runs and the rooms stay warm, or it will not start at all, we find out why and put it right. Mora Heating & Air repairs central air conditioning for homes in Germantown, Gaithersburg, Montgomery Village, Rockville, and the towns around them. You get a straight answer and the repair price in writing before we touch the equipment. If something else made that part fail, you hear about that too.
It starts with a call. We listen to what your system is doing, set up a visit, and tell you the diagnostic fee right there on the phone. Your technician tests the system, finds the fault, and writes down what failed and what the repair costs before any work begins. Nothing gets swapped out until you say yes.
Signs your AC needs a repair
Warm air from the vents
The system runs, but the air never turns cold. It often comes down to a failed capacitor, low refrigerant from a leak, or trouble in the compressor. The capacitor is the part that gives the motors their push to start. Each fault needs a different repair, so the visit starts with real testing, not a guess.
It starts and stops every few minutes
The unit kicks on, runs a couple of minutes, then shuts down again. That can mean a system too big for the house, a sensor going bad, or a refrigerant problem. Ignore it and the compressor takes the wear.
Ice on the copper lines
Ice on the copper lines or on the indoor coil tells you the airflow or the refrigerant is off. Turn the system off and let it thaw. Keep running it frozen and you can damage the compressor, which is the pump that moves refrigerant and the costliest part you own.
Water around the indoor unit
Your AC pulls water out of the air, and that water drains away through a pipe. When the pipe clogs, water backs up into the pan and spills on the floor. In a finished basement or a utility closet, that turns into ruined drywall and flooring. It is one of our most common summer calls.
The breaker trips when the AC starts
A breaker that keeps tripping usually means a compressor that struggles to start, a shorted wire, or a fan motor on its way out. Stop resetting it. Trips that repeat are telling you there is a real electrical fault.
Higher electric bills and weaker cooling
A system that has to run longer to do the same work is losing its cooling power. Dirty coils, low refrigerant, or a worn blower motor are the usual reasons. A diagnostic visit gives the problem a name.
What an AC repair visit looks like
You tell us what it is doing
We ask what your system is doing, when it started, and what equipment you have. We give you the diagnostic fee on that same call and get the visit booked.
Your technician tests the system
We read the wiring, the pressures, the airflow, and the drain. The point is to land on the real fault, not to grab the first part that is easy to swap.
You get the finding and the price in writing
Before any repair starts, you see what failed, why it failed, and what fixing it costs. You approve the work or you turn it down. Either answer is fine, and there is no pressure on you.
We do the repair and check it
We replace or correct the failed part, then run the system and take fresh readings to confirm it is cooling the way it should. You keep a record of what was done.
Repair or replace: how to decide
The age of the equipment and the kind of refrigerant it uses matter more than the size of any one repair. A system still running on R-22 refrigerant is hard to justify recharging, because that refrigerant is being phased out. When a compressor or a coil goes on a system already past twelve to fifteen years old, replacing it usually makes more sense than repairing it.
On newer equipment, most single-part failures are well worth fixing. Capacitors, contactors, fan motors, and drain problems are everyday repairs that give the system its full working life back. Your technician walks you through the repair price, the age of the unit, and what a replacement would take, so you decide with the facts in front of you.
AC repair in Germantown townhomes and Rockville ramblers
Our summers are humid, and an air conditioner spends as much of its work pulling water out of the air as it does cooling. All that water shows up as clogged drains and frozen coils. Look at the 1950s Twinbrook and College Gardens ramblers in Rockville, or the 1960s and 70s ramblers near Olde Towne Gaithersburg. The return ducts in those houses are too small by any modern standard. The main duct still runs through a crawl space or a low basement. A sound repair there has to take the ductwork into account, not just the equipment outside.
The Germantown townhomes are a different job. The indoor unit is usually stacked in a narrow closet or set up in the attic, and the whole house breathes through one filter grille in a hallway ceiling. When that grille loads up, the coil above it pays for it. Out in Clarksburg, most houses still run the equipment the builder gave them. The first summer fault there is normally a capacitor, a water safety switch, or a control board. It is rarely anything structural.
The part is usually the symptom
A capacitor rarely dies of old age on its own. It dies because the motor it was starting had to work too hard, and something made it work that hard.
Finding that something is the difference between a repair that holds and a repair that comes back. It is why we look at the whole system before we tell you what it needs.
What is your system actually doing?
If one of these is what you are seeing, start there. It tells you what is probably going on, and whether it is something you can check yourself.
AC Repair questions, answered
Why is my AC running but not cooling the house?
It usually traces back to a failed capacitor, a refrigerant leak, a dirty outdoor unit, or a compressor fault. They all feel the same at the vents, but each one needs a different repair. The system has to be tested before anyone names the fix. We set up a visit and tell you the fee when you call.
How much does an AC repair visit cost?
We tell you the diagnostic fee when you call, before anything goes on the schedule. Once your technician has tested the system, you get the repair price in writing and you decide whether to go ahead. Nothing surprising lands on the invoice, and no repair starts until you approve that price.
Is it worth repairing a 15 year old air conditioner?
Usually only for the smaller parts. Capacitors and contactors are sensible repairs at any age. A compressor or coil failure on a system that old is usually a replacement talk. The refrigerant may be obsolete, and the other parts are near the end of their lives. Your technician lays out both roads before you choose.
Why does my AC freeze up with ice on the lines?
Ice means the coil is getting colder than it should, usually from blocked airflow or low refrigerant. Check the filter first and switch the system off so it can thaw. If the ice comes back with a fresh filter, there is a leak or a mechanical fault, and running it that way puts the compressor at risk.
Why does my AC keep tripping the circuit breaker?
A breaker that trips as the AC starts usually means a compressor struggling to start, a shorted motor winding, or damaged wiring. Flipping it back on again and again is not safe, and it can turn a fixable fault into a burned compressor. Leave the breaker off and book a visit. We give you the fee when you call.
Do you repair heat pumps as well as air conditioners?
Yes. We work on central air conditioners, heat pumps, and ductless mini-splits in Germantown, Gaithersburg, Rockville, Potomac, Olney and the towns nearby. Out past the gas mains around Boyds, plenty of homes both cool and heat with the same heat pump, so we check both sides during the visit.
Do you fix window units or portable air conditioners?
No. We stay with central air conditioning, heat pumps, and ductless mini-splits. Window and portable units are sealed appliances that rarely pay off to repair. If a room leans on one, a ductless mini-split is the lasting answer, and we can look at that while we are there.
