Common Causes of Heating System Breakdowns

Heating systems break down for a variety of reasons, including:

  • High voltage: If your unit’s voltage is higher than your optimum capacity, your system can short circuit.
  • Dirty filters: Clean air filters promote smooth airflow and improve air quality in your home.
  • Broken thermostats: While seemingly easy to fix, calling an expert ensures a quick, efficient repair.

Heating Repair FAQs

Why is my heat not reaching the set temperature?

There are many reasons why your heating system isn’t reaching the desired temperature, including:

  • The thermostat is in the wrong location.
  • Your heating system needs repairs.
  • You have dirty air ducts or vents.
  • Wiring is loose in your thermostat.
  • Your thermostat needs new batteries.

Identify the cause of your heating malfunction by scheduling emergency heating repair with McCrea.

What is a heating leak search?

When your HVAC system has a refrigerant leak, detecting the source isn’t always easy. A leak search relies on bubbles or electronic leak detectors to pick up the tiniest leakages.

Do I really need to change my filters?

Proper airflow keeps your components cool. Without it, they can overheat and break down. Dirty filters also send dust and debris into your home, reducing your air quality.  

How do I know I have a carbon monoxide leak?

Even low levels of exposure can cause dizziness and nausea. This colorless, odorless gas is best avoided via frequent maintenance.
