AC Repair

AC Not Cooling? We Find Out Why.

The house is heating up and the AC just will not keep up. Warm air, weak airflow, or a unit that will not start can each mean something different. We come out, take real readings on the equipment, and tell you what is wrong before we fix anything. Call or text and we will get on it.

What AC Repair Covers

Warm air, weak airflow and a system that will not start can each come from a different thing. We get into the equipment, take real readings, and tell you what we found before we recommend a repair.

A burned-out capacitor, a bad contactor, a clogged drain, a weak blower or low refrigerant can all stop the cooling. We find the real cause and look at the whole system, not just the one part, before we tell you to repair or replace.

What This Covers

  • Diagnosis of the reported fault in the outdoor or indoor equipment within the agreed visit scope
  • Electrical fault finding: capacitors, contactors, relays, transformers, control boards, wiring
  • Refrigerant pressures and temperatures checked against the equipment instructions when operating conditions permit
  • Appropriate leak testing when readings suggest a refrigerant problem
  • Condensate drain and float-switch diagnosis, with any clearing or repair described in the agreed scope
  • Blower motor, blower wheel, and airflow problems, including a filter that has collapsed into the return
  • Frozen evaporator coil diagnosis, which is a symptom of something else rather than the fault itself
  • Thermostat wiring and control faults that look like an equipment failure but aren't
  • A written explanation of what failed, what we did, and what we saw that you should know about

Signs Your AC Needs a Look

  • The unit runs constantly but the house never reaches the setting
  • Air from the vents is moving but isn't cold
  • The outdoor unit hums and won't start, or starts and shuts down within a minute
  • Ice on the refrigerant line or on the indoor coil
  • Water around the indoor unit or a ceiling stain under an attic air handler
  • A breaker that trips whenever the system calls for cooling
  • A burning smell or smoke: stop using the equipment if safe and seek emergency help when needed

How We Work an AC Call

We listen to what the system is doing

Before anyone opens a panel we ask what changed and when. A unit that stopped overnight and a unit that has been weakening for three weeks are two different problems, and the history narrows it down.

We take readings before we take parts off

Electrical measurements, refrigerant readings, airflow checks and temperatures help narrow the cause. The tests depend on the symptoms, equipment and safe operating conditions.

We tell you what we found and what it takes

We explain the confirmed fault, what remains uncertain and the proposed repair. You receive the scope in writing before approving additional work.

We repair it and we verify it

After an approved repair, we run the relevant operating checks and explain the result. Any remaining issue or testing limitation is recorded.

Frequently Asked Questions

A low charge can involve leakage or an earlier charging or installation issue. Measurements and appropriate leak testing establish what is happening.
Yes. A restricted filter can reduce airflow. The correct filter and its condition are part of the assessment, but not every cooling problem is a filter problem.
We explain the evidence for each reasonable option, considering the fault, equipment condition, parts and any applicable coverage.
Describe what changed, when it started, any visible error message and whether the indoor and outdoor units run. Photos of accessible model labels can also help.
Stop cooling at the thermostat if safe and request service. Do not chip the ice or open the equipment. Follow equipment-specific advice about thawing.
Provide the brand and model so we can confirm the relevant service scope and parts requirements. We do not assume every model can be serviced the same way.
We serve homeowners in Germantown, Gaithersburg and Montgomery Village. Call or text with the full service address and the work you need so we can confirm the request.
No. A confirmed fault, overall condition, parts and applicable coverage are more useful than age alone when comparing repair and replacement.
An intermittent fault, unavailable part or operating condition may prevent a complete test. We explain what was confirmed and any further step needed.
The usual causes are a clogged filter choking the airflow, a dirty outdoor unit, low refrigerant from a leak, or a frozen coil. You can safely check the filter and make sure nothing is blocking the outdoor unit. If it is iced up, shut it off and let it thaw, then call us. We find the real cause instead of guessing at it.
It comes down to three things: how old the system is, what the repair costs against the value of the whole unit, and how well it has been keeping up. Once a system is past its teens and the repairs start stacking, replacement usually makes more sense. We look at yours and tell you straight which way we would go if it were our own home, with no pressure either way. Call or text 301-355-2238 and we will walk through it.

"I had a water leakage in my HVAC unit and Jay came out and did an amazing job on the repair. It took him longer than expected and he was working later into the night but made sure everything was done properly and efficiently. Super grateful for Jay's hard work and will definitely be reaching out for any future HVAC repairs I need!"

"Jay & his team are my goto for HVAC problems. Weather it's a small repair like replacing a capacitor or larger project like full system replacement. Jay and his team @ Mora Heating & Air do quality work at an affordable price but add top rated customer service that many large companies just can't & don't give."
