Heating Services in Mission Viejo
Furnace Repair Services for Mission Viejo Homes & Businesses
It doesn't get terribly cold here in Orange County, but the winter months can still be chilly enough that a working heating system is necessary. From heating repairs and yearly tune-up services to complete heating system replacements, Complete Comfort is your go-to heating company in Mission Viejo. Emergency service is available!
Call our Mission Viejo furnace repair team if you have noticed any of the following common issues:
- Your furnace smells odd. A smell of burning dust is normal if it's the first time you're turning on your furnace for the season. But if your furnace smells like burning plastic, diesel fuel, or natural gas, immediately turn it of and call for service.
- Your furnace is short cycling. If your furnace only runs in short bursts of about a minute or less, that isn't enough time to heat your home. Short cycling has numerous causes that should be assessed ASAP to prevent excessive wear and tear on your system and higher energy bills.
- Your furnace won't turn on. Is the pilot light out? Has a circuit breaker tripped? Has your thermostat reset itself? If you still need help, give us a ring!
- Your furnace runs, but you're only getting cool air. If you're getting cold air from your return vents when your furnace is running, you may have a problem with a dirty air filter, leaking air ducts, an incorrect thermostat setting, a clogged condensate drain line, or your furnace's fuel source.
New Furnace Installation & System Replacement
If the time has come for you to replace your old furnace, Complete Comfort can help you choose the right system based on your needs. With a wide variety of options on the market, you can reap the benefits of an energy-efficient system that will provide you with more reliable comfort and lower costs of operation. If you have questions about Annual Fuel Utilization Efficiency (AFUE) ratings for furnaces and what rating you should aim for when selecting a furnace, we can guide you.
A note about carbon monoxide: Be aware that older gas furnaces run a higher risk of carbon monoxide (CO) leaks due to age-related corrosion of the heat exchanger. This colorless, odorless gas is a biproduct of combustion that is safely vented outside of your home when your furnace is working properly, but if your heat exchanger becomes cracked due to age or poor maintenance, the gas could end up leaking into your indoor air. CO poisoning can be fatal, so don't delay professional furnace repair, maintenance, or replacement.
