3 Reasons Your Furnace in Lake Worth, FL, Turns On and Off Frequently

When your home in Lake Worth, FL, feels cold, there’s no more welcome sound than that of your furnace operating. However, if you hear this sound too many times during a typical day, it could indicate that there’s a problem. Here are a few common reasons that your furnace turns on and off frequently:

Poor Insulation

If your heater turns on and off frequently, it may have nothing to do with the system itself. Instead, it could indicate that your home lacks adequate insulation to hold onto warm air.

As the air escapes, your furnace will have to turn on frequently to replace the air you’ve lost. Making sure your home is adequately sealed and insulated can go a long way in helping your heater run more efficiently.

Clogged Air Filter

Another common cause of a furnace that isn’t operating properly is a clogged air filter. An air filter that’s completely clogged can reduce the amount of air that flows to your heat exchanger, which can cause it to overheat.

To protect your heat exchanger and prevent the need for a replacement, your furnace has a high-limit switch that shuts it down when the temperature gets too high. Make sure to regularly change or clean your air filters and schedule maintenance to prevent this issue from occurring.

Incorrectly Sized Furnace

If you’ve recently had your furnace replaced, your problems could be due to an incorrectly sized system. If an HVAC company doesn’t properly size the furnace to your home, it’ll likely either provide too much or too little heating capacity, leading to erratic operation. This can be frustrating, and it’s important to address this problem quickly so that you can improve your home’s comfort.

Your heating system is complex and requires ongoing care to operate properly. If you need to repair or replace a furnace that continually turns on and off, contact us at Preferred Air Conditioning & Mechanical, LLC.
