Furnace Repair
No heat, short cycling, or a furnace that locks out.
See furnace repairRepair when repair is the right answer. Replacement when the condition of the equipment and the repair options justify it. Mora Home Services repairs, maintains and replaces furnaces, heat pumps, ductless systems and central air across upper Montgomery County. A technician tests the system and explains the findings before a part is replaced. You get the price in writing after the diagnostic visit, before any repair begins.
We install and service Daikin, Goodman, Ruud, Carrier and Bryant equipment.
Paid diagnostic visit. Written price before any repair.
We diagnose the fault, tell you what it takes to repair it, and recommend replacement only when the condition of the equipment justifies it. You get a written quote before any work begins, and a straight answer about what your system needs.
A diagnostic visit is an on-site assessment to find the cause of a system fault. Depending on the equipment, the checks can include electrical readings, airflow, temperature, controls and refrigerant measurements. We explain what those findings mean for your system.

|---|---|
| A repairable fault in otherwise sound equipment | Repairing the failed part or correcting the fault. |
| A major component has failed | Repair options, any applicable manufacturer coverage, and replacement options. |
| Repeated failures or poor comfort | The cause of the pattern and whether equipment replacement would address it. |
| An older system with a refrigerant leak | Leak repair, refrigerant and parts support, and the practical replacement options. |
No single symptom decides the answer. We explain the findings and proposed work in writing, and you decide.
The problems that bring most of our heating and cooling calls, in the words people use when they call. Each one starts with a paid diagnostic visit and a written price before any repair.
We sell and install Daikin, Goodman, Ruud, Carrier and Bryant equipment. Which system suits a house depends on the house, the existing equipment and what you want from it.
Inverter and side-discharge options are part of that conversation where they suit the installation. The recommendation starts with the home.
Book a diagnostic visit and tell us what the equipment is doing.
The technician tests the system and explains the findings. The equipment determines which readings are needed.
You approve the repair before work begins. If replacement deserves consideration, we explain why.
From our office in Gaithersburg, we serve these towns in upper Montgomery County.
Heating and cooling: 8 AM to 7 PM, every day.
We repair furnaces, air conditioners, heat pumps and ductless systems. Replacement is a conversation we have when the equipment condition justifies it, and we show you what we found.
Yes. A heating or cooling fault starts with a paid diagnostic visit. You receive the findings and a written price before any repair begins.
Short cycling can have several causes, including airflow, ignition, control or thermostat faults. A diagnostic visit identifies the cause in your system before a repair is proposed.
Yes. Heating and cooling runs 8 AM to 7 PM, every day, including Saturday.
Yes. We repair, maintain and install heat pumps and ductless mini-split systems, including inverter equipment.
No. We repair, replace and install equipment: furnaces, heat pumps, air handlers, condensers, ductless heads and thermostats. If a duct problem is affecting comfort, we explain that before recommending equipment.
Yes, and we show you why. Age alone does not decide it. Condition, the repair needed and the options for your home all matter.
Give the system a few minutes; a heat pump can run cooler than a furnace at first. Then check that the thermostat is on Heat, the set temperature is above the room temperature, the filter is not loaded, and the furnace switch and breaker are on. If the fan runs but the air never warms, or the system keeps shutting off, book a diagnostic visit. We test the sequence and tell you what failed before any repair.
Choose a diagnostic visit for a system fault, or a maintenance visit for a seasonal tune-up. Heating and cooling runs 8 AM to 7 PM, every day.
