Seasonal & Emergency HVAC Help

When heat or AC quits in extreme weather, run a few quick checks, then call — we offer same-day and emergency service. If you ever smell propane or a CO alarm sounds, get outside first and call from a safe spot.

When your heat or AC quits in extreme Zone 5A weather, run a few quick checks, then call — we offer same-day and emergency service. But safety comes first: if you ever smell propane or a carbon monoxide alarm sounds, get everyone outside and call from a safe spot before anything else.

What counts as an HVAC emergency?

Out here, "emergency" usually means no heat when it's heading toward −20°F, no cooling during a dangerous heat wave, or any sign of a safety problem — a propane smell, a carbon monoxide alarm, or a burning odor from the system. Lost heat in deep cold isn't only uncomfortable; it puts your pipes at risk of freezing. When the weather is severe and vulnerable family members are home, treat a failure as urgent and don't wait it out.

What should you check before you call?

A few quick things solve a surprising number of "no heat" and "no cool" calls. Make sure the thermostat is set to heat or cool and a few degrees past the room temperature, and try fresh batteries. Check that your air filter isn't clogged — a dirty filter chokes airflow and can shut a system down, which is why we suggest checking filters monthly out here. Look at your electrical panel for a tripped breaker, and clear snow, ice, or tall grass away from the outdoor unit. If none of that brings it back, it's time to call.

Safety first: propane and carbon monoxide

We have no natural-gas mains here, but propane and combustion still demand respect. Propane has a rotten-egg odor and is heavier than air, so it settles low. If you smell it, don't flip switches — leave the house and call your propane supplier and us from outside. If a carbon monoxide alarm goes off, get everyone to fresh air immediately and call 911. In deep cold while you wait for help, protect your plumbing: let faucets drip, open the cabinet doors under sinks, and keep interior doors open so what heat you have can move around.

When a heat pump looks broken but isn't

In cold, damp weather an air-source heat pump will periodically run a defrost cycle — you may see steam off the outdoor unit and feel auxiliary backup heat kick in for a few minutes. That's normal, not a breakdown. If you want to understand how these systems behave in our winters, cold-climate heat pumps in Zone 5A explains what to expect.

How we handle emergencies

We offer same-day and emergency service across our rural footprint, and we're licensed, insured, EPA-certified, and family-owned. Our regular hours are Monday through Friday 7am to 7pm and Saturday 8am to 5pm, with Sundays reserved for emergencies. The best defense, though, is staying ahead of trouble — most no-heat calls trace back to skipped upkeep, so regular HVAC maintenance is the cheapest insurance against a midnight failure.

What to do next

If your system is down in hard weather, don't tough it out. Contact us or call 660-947-3354 right away — for true emergencies, calling is fastest — and we'll get to you as soon as we can.

FAQ

Frequently asked questions

Do you offer emergency HVAC service?
Yes. We offer same-day and emergency service across our rural service area. Our regular hours are Monday–Friday 7am–7pm and Saturday 8am–5pm, with Sundays reserved for emergencies. For an urgent no-heat or no-cool situation, calling is the fastest way to reach us.
What should I do if I smell propane?
Treat it seriously. Don't flip switches or light anything — leave the house, and from a safe spot outside call your propane supplier and us. If a carbon monoxide alarm sounds, get everyone to fresh air and call 911 first.
My heat pump is steaming and blowing cooler air — is it broken?
Usually not. In cold, damp weather a heat pump runs a normal defrost cycle, melting frost off the outdoor coil while backup heat takes over briefly. If it never returns to normal heating, or you see ice building up and staying, give us a call.
