Why Is Your Furnace Not Blowing Hot Air in Cooper City, FL?

Top Reasons Why Your Furnace Is Not Blowing Hot Air in Cooper City, Florida

There are a whole range of reasons why your furnace may have stopped blowing hot air, from a simple dirty filter to a much more serious mechanical problem. The help of a professional HVAC technician comes in handy when you’re facing these common reasons for your furnace not blowing hot air:

The Furnace’s Thermostat Settings Are Wrong

Let’s start with the easiest issue: thermostat trouble. 

Is your thermostat set to heating mode? Have you set it to the temperature you want? If you’ve mistakenly clicked the thermostat reading too low, it’s not going to heat your space effectively.

If you notice that the thermostat has no power, try changing the batteries. Thermostats hardwired to your home’s electrical system may just need a reset. Schedule a thermostat repair right away if these efforts don’t restore your heating.

Your Furnace Has a Clogged Air Filter

Your furnace’s air filter will trap all kinds of debris, from dust bunnies to pet dander. Capturing debris prevents that stuff from blowing through your home and contaminating your breathing air. However, if the filter becomes too dirty, your indoor air quality will still suffer. 

Wait too long to replace it, and the unit will struggle to heat your home or shut down entirely. Replace your furnace filter every 30 to 90 days. 

Your Ductwork Needs Cleaning or Leak Repair

Ductwork is an essential part of your heating system. It doesn’t matter how well-maintained your furnace is if the ductwork isn’t in good shape. The warm air your system produces will struggle to reach the rest of your home.

It’s common for ducts in Cooper City to clog with spider webs, dust, hair, and even animal nests. HVAC technicians like Cool By Design can inspect these channels and give them a thorough cleaning that goes beyond a broom, brush, or vacuum cleaner.

While the team is poking around in your home’s vents, they also look for cracks and holes. Sealing these gaps – even with mastic or duct tape – can be an inexpensive way to resolve ductwork problems and improve your furnace’s efficiency.

The Furnace Has a Malfunctioning Thermocouple or Ignition Problems

Is the furnace not blowing hot air? Your furnace’s thermocouple is a safety device that turns off the system if the pilot light goes out. Sometimes, cleaning and relighting the pilot light is enough to restore your hot air supply, but a malfunctioning thermocouple will continue to trip even after relighting the pilot.

If your pilot light keeps going out or refuses to start at all, you may have something blocking the gas supply instead. A qualified HVAC technician in Cooper City will have to resolve these furnace problems for safety reasons.

Furnace Blower Motor Issues

The blower motor is an integral part of your heating system, pushing heated air through your property’s ducts. If your blower motor fails, you may not feel any air, warm or otherwise, coming through the vents.

Blower motors can fail due to electrical problems, worn bearings, and a lack of maintenance. You’ll need Cool By Design’s HVAC professionals to help you repair or replace yours.

The Entire Furnace Needs Replacing

At some point, your old furnace will stop heating your home effectively. Is the furnace taking a long time to reach your desired temperature? If your furnace is 15 to 20 years old, it’s time to start thinking about a replacement. 

You may opt to replace yours with a similar model or a heat pump, which provides both heating and cooling. This is often the perfect heating system for a Cooper City home since it handles Florida’s mild winters well.
