Furnace Not Blowing Hot Air: Causes & Solutions

Most homeowners need to increase the heat a couple more times before the cold weather is officially over. That’s why a furnace not blowing hot air might be a serious issue. There is a high likelihood that you can only resolve the issue if you seek professional assistance from heating services in Grand Rapids.

Reasons why the furnace is not blowing hot air

Below are some causes if you’ve turned on the heat only to discover a cold air entering your house. Additionally, we will provide you with a few potential do-it-yourself fixes for a furnace. If this does not resolve the issue, you should contact heating services experts.

  • Thermostat problems

The thermostat may be the source of the issue producing cold air instead of the heat you want. Here is where you should concentrate your initial troubleshooting efforts. There are numerous types of thermostat problems and an equal number of fixes.

Many homeowners have chosen new thermostats incompatible with their home’s pre-existing heating system. The best course of action if you believe such is what has happened in your case is to contact an HVAC professional who can quickly identify the situation.

A furnace service in Grand Rapids, can sort it out and figure out what’s causing your thermostat problems, even if there exists a cobbled-together system of DIY components.

  • Filter problems

There is still another human error that can cause your cold air problems. One further “simple” cure is to change the filter in your heating system after you’ve checked the batteries and checked with household members for any thermostat-adjusting actions.

A clogged, dirty, old filter can hamper your HVAC system’s ability to move air. The ability of your furnace to generate and transport warm air around your home could be hampered as a result. Some furnaces even have a built-in shutdown that activates when the filter becomes blocked to avoid a burner overheating.

The furnace will then start to blow cold air. If replacing the filter and restarting the system doesn’t work, you should speak with an HVAC professional.

  • High-limit switch problems

Some HVAC system components may malfunction due to an uncared-for unclean filter. Although your system can withstand a few overheating episodes, it cannot continue indefinitely. Continual overheating can cause your high-limit switch to malfunction.

Another reason you might require an HVAC technician’s assistance is if the switch is difficult to locate.

  • Issues with condensate line

The condensation in your HVAC system is another element that needs routine maintenance. The condensing unit in your HVAC system drips water into a drip pan continuously when running in hot weather. The water is taken away through plumbing and eventually drains outside your house. Also, know should you repair or replace your furnace? 

Those lines tend to accumulate dirt and grime, especially if you don’t give them routine maintenance. For cleaning out sticky condensate pipes, HVAC companies have a variety of specialized gear at their disposal.
