CO alarm or symptoms
Headache, dizziness, weakness, upset stomach, vomiting, chest pain, confusion, or a sounding CO alarm means fresh air and 911. Don't stay inside to find the source.

No-Heat Emergency Help in Frederick, MD
If your Frederick County home has no heat, first decide whether you have a safety emergency or a heating repair problem. A carbon monoxide alarm, gas odor, smoke, burning smell, or serious illness means leave the home and call 911 from outside.
The first decision
If there's no immediate danger, make a few low-risk checks, protect people and pipes from the cold, and call us. HVAC troubleshooting comes after the home's cleared.
Safety before troubleshooting
Some no-heat calls start with 911, not us.
Carbon monoxide is odorless and colorless. A working CO alarm belongs on every level of the home and outside sleeping areas.
Gas odor, smoke, or burning smell
Leave and call 911 or the utility from a safe location. Don't restart a furnace that may be producing combustion gases, and don't run a fuel-burning appliance you suspect is malfunctioning.
EPA fresh-air guidanceFreezing weather and no heat
Check on children, older adults, people with medical needs, pets, and plumbing at risk in exterior walls, basements, crawlspaces, attics, and cabinets.
No danger warning, but no heat
Keep the checks simple. You're collecting useful information for us, not repairing the system or guessing which part failed.
The CPSC recommends professional inspection of fuel-burning heating systems and testing CO alarms per the manufacturer's instructions. See CPSC winter heating guidance.
Only when the home is safe
Six observations that help before you call.
Stop if you find a burning electrical smell, smoke, water near electrical equipment, repeated breaker trips, or an unusual fuel odor.
- 01
Look at the thermostat.
Confirm it's set to Heat, the temperature's above the current room temperature, and the display's on. If it's blank, note that. Change batteries only when the thermostat's designed for homeowner battery replacement and the instructions are clear.
- 02
Notice what the system is doing.
Is the furnace, air handler, heat pump, or boiler quiet? Does it start and stop? Do the registers blow room-temperature air, or is there no airflow? Write down what you hear and when it started.
- 03
Check the accessible filter.
If the filter's visibly loaded with dust, photograph it or note its condition for the service call. Don't force a filter into place or guess at the size.
- 04
Look at registers and returns.
Move furniture, rugs, or storage that blocks a register, and keep the observation on the room side of the grille. Don't remove duct panels or equipment covers.
- 05
Look outside from the ground.
Snow or ice on an exterior furnace, boiler, or heat-pump vent? Write down what you see. Don't climb onto a roof, reach into a vent, or chip at a vent connected to fuel-burning equipment.
- 06
Note a recent change.
Record a power outage, storm, fuel delivery issue, water near equipment, tripped safety control, or nearby work. Don't remove electrical covers, handle gas controls, open a combustion chamber, or keep resetting a breaker.
Don't remove panels, handle gas controls, open a combustion chamber, test live wiring, or keep resetting a breaker or furnace safety switch. Tell us exactly what you saw. If the condition could threaten people or the building, call 911 first.
The symptom is the starting point
"No heat" describes what the house feels like. It doesn't tell either of us which part failed — that takes testing.
No airflow is a different clue from cool airflow.
Weak airflow, no airflow, or air that never turns warm point us toward different parts of the system. A clogged filter, duct gap, or insulation problem may affect performance, but the symptom alone doesn't prove which part failed.
Record what the indoor and outdoor units do.
Note whether the outdoor unit starts, whether indoor air feels different from room temperature, and whether the problem started during a weather change. Don't assume refrigerant, defrost, or electrical work is needed.
Cold rooms can start with the boiler or the emitters.
A boiler problem may involve controls, circulation, water, fuel, or another component. Note which rooms are cold, and whether any water's leaking, then leave the cabinet and pressure controls alone.
A cold house isn't a diagnosis by itself.
We test the system before anyone recommends a repair or a replacement. Age, repeated breakdowns, safety concerns, and the cost of a major component can shape the decision once we understand what actually failed.
A forced-air system, heat pump, boiler, or electric furnace needs measurements and safe equipment access before we can say what repair is needed. The Department of Energy explains how equipment, ductwork, insulation, air sealing, and thermostat settings affect HVAC performance.
While help is being arranged
Make the wait safer, not riskier.
Temporary measures can make a short wait more manageable, but they don't replace a heating repair.
Slow the heat loss.
Close off unused rooms, close blinds or curtains after daylight, and use towels at the bottoms of exterior doors. Put on warm layers and find a safer heated location if the home's turning unsafe.
Use electricity carefully.
Place a portable electric heater on a stable surface at least 3 feet from bedding, curtains, furniture, and other materials that can burn. Plug it directly into a wall outlet, not an extension cord or power strip. Turn it off when you leave or sleep.
Don't burn fuel indoors.
Never use a gas range, oven, grill, charcoal appliance, or fuel-burning camping device to heat the house. Never run a generator inside a home, basement, garage, shed, or enclosed area.
EPA generator and vent guidanceKnow where the water shutoff is.
Watch vulnerable plumbing in exterior walls, basements, crawlspaces, attics, and cabinets. If a pipe bursts, shut off the main water when you can do so safely. Protecting the home comes after protecting people.
When you request service
Bring the symptom, not a guessed diagnosis.
A clean description helps us start with the real problem in your Frederick County home.
No-heat questions
What Frederick County homeowners ask first.
Answers for the minutes before you call us.
Is no heat always an emergency?
No. A home without heat needs quick attention, especially in cold weather, but a CO alarm, gas odor, smoke, serious illness, or dangerous indoor temperature turns it into a safety emergency. Leave and call 911 from outside when those signs appear.
Should I keep resetting the furnace?
No. If the system won't start after a normal homeowner control check, repeated resets can hide the symptom or return an unsafe appliance to operation. Write down what happened and let us diagnose it. Don't bypass a safety switch.
Can I use my oven to warm the house?
No. A gas oven, range, grill, or other combustion appliance isn't a safe substitute for home heating. Fuel-burning appliances can add carbon monoxide and other combustion products to indoor air.
What if my heat pump is running but the house stays cold?
Record whether the outdoor unit runs, whether air's moving indoors, and when the comfort problem started. Check the thermostat and accessible registers, then call us if the home won't warm up. Don't buy refrigerant or assume a particular component failed.
Do I need emergency HVAC help or a regular repair visit?
Use the danger signs to decide urgency. CO or gas concerns mean call 911 first. A home losing heat in freezing weather, a vulnerable occupant, or a system that won't start at all — call us right away.
What should I do after the heat comes back?
Ask us what caused the failure and whether any safety or venting issue was found. Replace or clean filters per the equipment instructions, keep exterior vents clear, and book us for fuel-burning equipment service. If the same symptom returns, write down the pattern instead of waiting for a total loss of heat.
