Heating Repair in Rockville, Germantown and Olney, MD
Waking up to a cold house leaves you with one real question. What broke in your system, and how soon can someone fix it? Mora Heating & Air works on gas furnaces, propane furnaces, and heat pumps in Rockville, Germantown, Gaithersburg, Olney, Derwood and Montgomery Village. We work on hot water boilers too, along with the radiators or baseboard they feed. Steam boilers and oil equipment are outside what we do, and we tell you that on the phone rather than burning a visit to find out.
Every repair starts with a conversation. You tell us what your system is doing, we set a visit, and we tell you the diagnostic fee right there on the phone. Your technician runs the system, walks you through what failed, and hands you the repair price in writing before anyone picks up a tool. On gas and propane equipment, that visit also includes a carbon monoxide safety check.
Signs your heating system needs a repair
No heat at all
Your system will not start, or it starts and never warms up. Before you call, check your thermostat batteries, your breaker, and the switch on your furnace. If all three are fine, the trouble is inside the equipment.
Warm air never arrives
When the blower runs and the air stays cold, the furnace is usually failing to light. Or the flame sensor is dirty. Or a safety control tripped because something is overheating. The flame sensor is a thin rod that proves the burners lit. Each of those is a specific fault we can test for.
It keeps starting and stopping
It fires up, runs a moment, then shuts down, over and over. The usual suspects are a dirty filter choking your airflow, a sensor on its way out, or a furnace too big for your house. All that cycling grinds on parts and burns fuel.
The flame does not look right
A healthy gas flame is blue and steady. When it turns yellow or orange, or flickers and dances, the gas is not burning cleanly, and that can release carbon monoxide. This one deserves a professional look rather than a wait and see.
Sounds you have not heard before
A noise that was not there last winter means something in your system changed. Bangs usually mean gas building up before it lights. Squeals mean belts or tired motor bearings. Rumbles come from the burners. These sounds almost never sort themselves out, and they get more expensive the longer they run.
Cold rooms and rising fuel bills
When your system has to run longer to hold the same temperature, it is losing capacity. A dirty burner, a weak blower, or a duct problem can each be behind it. Testing is what tells you which one.
How a heating repair visit goes
You walk us through it on the phone
We ask what your system is doing, what fuel it runs on, and how old it is. We give you the diagnostic fee on that same call and set the appointment.
We inspect and test
Your technician checks the ignition, the flame, the gas pressure, the electrical parts, and the airflow. Heat pumps also get their refrigerant and their frost cycle tested. The aim is to land on the real fault, not chase a symptom.
You see the finding and the price in writing
You learn what failed and what your repair will cost before any work starts. You approve it or you turn it down in writing. Turning it down is a perfectly good answer when the numbers do not work for you.
We repair it, then confirm it is safe
We correct the fault and run the system through full cycles. On gas and propane equipment, we check how the gas is burning and take a carbon monoxide reading before we close out the visit.
The point where repair turns into a replacement talk
The heat exchanger usually draws that line. The heat exchanger is the metal chamber that keeps exhaust out of the air you breathe. A cracked one cannot be patched, and on a furnace already past its midlife the honest call is a new furnace, not a single part. Ignitors, flame sensors, control boards, and blower motors sit on the other side of that line. They are routine repairs that make sense at nearly any age.
Age carries the rest of the weight. If your furnace is past fifteen to twenty years, or your heat pump past twelve to fifteen, other parts are drifting toward failure even when today's problem is small. Your technician lays the repair price and the replacement picture side by side. The choice stays yours, and you make it with the whole story in front of you.
Heating repair in Rockville, Derwood and Boyds homes
Natural gas reaches most of the streets we cover. Gas furnaces fill the 1950s ramblers in Twinbrook and College Gardens, and the 1970s and 80s houses around Mill Creek Towne and Derwood Station. A lot of those Derwood homes are on their third system by now, and every changeover left something behind. A duct transition that does not quite fit. A return nobody enlarged. A flue that got adapted instead of replaced. So a proper repair visit reads the venting alongside the equipment.
Past the gas mains around Boyds, houses sit on well and septic with real distance between them. The heat there comes from a propane furnace or a heat pump. Both are everyday work for us. We plan the likely parts before the visit, because a second trip out there costs you a day rather than an hour. In Clarksburg, the original builder furnaces and heat pumps from the 2000s and 2010s are now showing their first real failures.
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.
Heating Repair questions, answered
Why is my furnace blowing cold air?
Usually a failed ignitor, a dirty flame sensor shutting the burners off, or an overheating furnace tripping its safety, often because of a dirty filter. Start with your filter. If it is clean and your air is still cold, book a visit. We tell you the fee when you call.
Why does my furnace keep turning on and off?
That start and stop pattern usually means blocked airflow, a flame sensor on its way out, or a thermostat problem. Now and then the furnace was too big for the house from day one. It burns extra fuel and wears out the ignitor and blower early, so it is worth pinning down. On-site testing names the exact cause.
Do you repair boilers or oil furnaces?
Hot water boilers, yes. We work on hot water heat and the radiators or baseboard it feeds. Steam boilers and oil equipment are the ones we do not touch. Describe your system when you call. If it is outside what we handle, you hear that on the phone, so you are not paying for a visit that leads nowhere.
Is a cracked heat exchanger dangerous?
It can be. The heat exchanger keeps exhaust gases out of the air moving through your house. When it cracks, carbon monoxide can get into the air you breathe. If we find a crack on your furnace, it should stay off until it is replaced. Every gas and propane heating visit we run ends with a carbon monoxide reading.
How much does heating repair cost?
We tell you the diagnostic fee when you call, before anything is booked. Once your technician finds the fault, you get the full repair price in writing, and nothing moves forward without your approval. What it costs depends on which part failed, so no honest figure exists until the system has been tested.
Do you service propane furnaces out around Boyds?
Yes. Propane furnaces show up often past the gas mains around Boyds, on the properties out on well and septic, and they are steady work for us. Propane burns at its own pressures and settings, so the visit includes testing set to propane rather than natural gas.
What should I check before calling for no heat?
Three things. Check that the thermostat has fresh batteries and is set to heat. Look at the breaker panel for anything tripped. Check your furnace switch, which looks like a light switch near the unit and gets flipped off by accident more than you would think. If the heat is still out after those, call and we will set up the visit.
