Homeowners' pick for heating and cooling across Virginia and the Mid-Atlantic
Smelling Gas at Home
You walked past the furnace and caught that rotten-egg smell. Maybe it is faint, maybe it hits you at the basement stairs. Either way, you want to know what to do in the next two minutes, not next week. Here is the order we tell homeowners to follow: get everyone out, call for help, then worry about the furnace itself.

Step One: Leave the Building, Then Call 911 or the Gas Utility
If you smell gas near the furnace, get everyone out of the house first, then call 911 or your gas utility from outside. That order matters. Do not stop to find the source, shut anything off, or open windows on your way out. Take the people and pets with you and walk to the sidewalk or a neighbour's yard. The gas utility sends someone to check the line and the meter, and they can shut off supply at the street if needed. They do this all day and they do not charge you for the trip in most service areas. Only after they clear the house do you start thinking about repair.
What Not to Do While You Are Still Inside
Do not flip light switches, unplug anything, or use the garage door opener. Those all make a small spark. Do not light a match or a lighter to see better. Do not use your phone inside the house, even to call for help, and do not start a car in an attached garage. Skip the exhaust fans and skip the thermostat. We also ask homeowners not to touch the gas valve on the furnace or the shutoff at the meter. If the leak is at a fitting, moving that valve can make it worse, and the utility has the tools and the gauge to confirm the line is actually tight.
Carbon Monoxide Is a Different Warning Sign
Natural gas is odourised so you can smell it. Carbon monoxide has no smell at all, which is why a detector matters. If a CO alarm sounds, treat it exactly like a gas smell: everyone outside, then call 911 from outside. Headache, nausea, dizziness or sleepiness that clears up when you step outdoors is worth an urgent call too, and worth telling a doctor about. CO usually points to a combustion problem, a cracked heat exchanger, a blocked flue or a vent that came loose. That is a repair question, and it comes after the emergency responders have been through.
When to Call Us, and What We Look At
Call us once the gas utility has been out and the house is clear. We handle heating repair across Virginia, Maryland, Delaware, Washington DC, North Carolina, New Jersey, Pennsylvania and West Virginia, and a suspected gas issue moves to the front of the schedule. On site we test the gas train and the connections at the furnace, check the burners and the heat exchanger, look at the flue and the draft, and confirm the safeties actually shut the unit down. Sometimes the smell traces to a loose union or a bad pilot assembly. Sometimes the furnace is old enough that repair stops making sense, and we will say so plainly.
Small Smells and False Alarms
Not every odour near the furnace is a leak, but you still treat it like one until someone confirms otherwise. A brief burnt-dust smell the first time heat runs in the fall is normal and fades in an hour. A sewer-like smell in a crawlspace or basement can be a dry trap or standing water, common through damp shoulder seasons in older homes across the region. Rotten egg or sulphur is the one that means gas. If you are unsure which you are smelling, go outside and call the utility. Guessing wrong costs nothing when you guess toward safety.

Smelling Gas at Home — straight answers
Should I turn off the gas to my furnace myself?
No. Leave the valve alone and get out of the house, then call 911 or the gas utility from outside. They can shut the supply off at the meter safely and confirm whether the line is holding pressure.
Can I stay in the house if the smell is very faint?
We would not. Gas concentration changes as it collects, and a faint smell in one spot can be stronger elsewhere. Step outside, call the gas utility, and let them measure it rather than judging by nose.
What happens after the gas company clears my house?
They may leave the furnace shut off and red-tagged. At that point call us for heating repair. We test the gas connections, burners, heat exchanger and venting, then tell you what needs fixing.
How it works
- Step 1
Tell us the symptom
Call or fill in the form and describe what changed. Warm air, short cycling, a smell, water near the indoor unit. Details like that help us load the right parts before we leave.
- Step 2
We diagnose the whole system
We check the thermostat, the indoor unit, the outdoor unit and the ductwork, including runs in crawlspaces where damp air and loose joints quietly cause weak airflow and long run times.
- Step 3
You approve the fix
We explain what failed, what it takes to repair it, and what we would watch next season. Nothing gets replaced without your yes, and we clean up before we leave.

Why homeowners call us
- Humidity is our home groundMuggy summers and damp shoulder seasons drive most of the calls we take. We look at moisture and airflow together, not the cooling number alone, because a clammy house often means a sizing or duct problem.
- Crawlspace ducts get checkedOlder homes across the region run supply ducts through vented crawlspaces. Crushed flex, disconnected boots and soaked insulation show up constantly, and we get under the house to look instead of guessing from the register.
- Heating and cooling bothSame crew for air conditioning repair in July and heating repair in January. We know how your furnace, heat pump and air handler share ducts and a blower, so one visit covers the whole system.
- Plain talk on repair or replaceWhen a repair makes sense, we repair it. When a system is failing in ways that will keep costing you, we say so and explain why, then leave the decision with you and your timeline.
