Furnace and heat pump repair, open until midnight every day
Mountain Valley Home Comfort repairs furnaces, heat pumps and dual-fuel systems from four offices, in Harrisonburg, Staunton, Winchester and New Market. We’re open until midnight every day, with 24-hour emergency service after that, so a breakdown on a cold night doesn’t have to wait until morning. A technician finds the cause, explains what failed and what it will take to fix it, and gets your heat back on. We’ve been family-owned since 1984, and we work on all makes and models, not just the systems we install. If your furnace or heat pump is acting up but still running, call anyway. A small problem caught early, like a weak capacitor or a dirty flame sensor, is a much cheaper fix than a system that fails on the coldest night of the year.
What heating problems do we fix?
- No heat, or the system runs but blows cool air
- A furnace that won’t light or keeps shutting off
- A heat pump that ices over, won’t defrost or runs nonstop
- Short cycling, where the system turns on and off every few minutes
- Banging, squealing or rattling noises, or a burning smell that doesn’t go away
- Rooms that won’t warm up, or heating bills that jump for no clear reason
- Thermostat and wiring problems
If you smell gas or your carbon monoxide alarm goes off, leave the house now. Call your gas company or 911 from outside, then call us.

What can you check before you call?
A few quick checks fix a surprising number of “no heat” calls, and they take about five minutes:
- Thermostat. Make sure it’s set to Heat, the setpoint is above room temperature, and the batteries aren’t dead.
- Air filter. A clogged filter can make a furnace overheat and shut itself off. Replace it if you can’t see light through it.
- Breaker. Check the panel for a tripped heating breaker and reset it once. If it trips again, leave it off and call us.
- Furnace switch. The switch on or near the furnace looks like a light switch. It should be on.
- Outdoor unit. Clear snow, ice and leaves from around your heat pump.
A heat pump that steams for a few minutes in cold weather is usually just defrosting, which is normal. If you’ve worked through the list and still don’t have heat, call us. Our no-heat checklist goes through each step in more detail.
Should you repair or replace your heating system?
Repair is usually the right call on a system with good years left. Replacement is worth a look when a furnace is past 15 years or a heat pump is around 15, and the repair is a major one like a compressor or heat exchanger. In that case, we’ll give you the repair price and replacement options at the same visit, so you can compare real numbers and decide. Learn more about heating installation and replacement.
How do you prevent the next breakdown?
A yearly tune-up catches most problems before they leave you without heat. Members of our Home Comfort Club get their tune-up, priority emergency service and a discount on repairs. Learn more about heating maintenance.

Heating repair FAQ
Why is my heat pump blowing cool air?
Heat pump air feels cooler than furnace air even when it’s working, because it heats the air to a lower temperature over a longer run. Cool air for a few minutes in cold weather is usually the defrost cycle. If the air stays cool, the outdoor unit is iced over, or the system never shuts off, call for service.
Is it OK to use emergency heat?
Yes, for a short time. Emergency heat uses the backup heat strips, which keep you warm but cost a lot more to run than the heat pump. Use it to get through until a technician arrives, then switch back.
Is there a charge for a service call?
Yes. Each repair visit has a dispatch fee, and visits after hours cost more. Home Comfort Club members save on both.
