Basic maintenance can help reduce the need for costly heating repair services, but not all problems can be fixed by replacing filters and cleaning vents. If an HVAC system is not working properly, it’s important to call in professionals at the first instance of any of these warning signs.

Overall Failure

If the system doesn’t turn on, even though the temperatures in the home should trigger a start, the thermostat may be faulty. The thermostat regulates the demand for hot or cold air, switching the system on and off as needed. Sometimes the thermostat may accidentally switch off or be adjusted to the wrong setting, and it only needs to be turned on again. In other cases, the electrical components wear out, and the system cannot function normally. A professional can replace the thermostat to ensure proper heating and cooling. Newer thermostats even have Wi-Fi capabilities, giving homeowners the option to adjust the temperature anywhere and at any time.

Failure to Adequately Heat the Home

Before contacting a technician, check to make sure the system is in heat mode and that the pilot light is lit. If these issues are not causing the problem, it’s time to call a professional. A furnace that has clogged filters, a faulty thermocouple, or one that is simply too small for the space will not be able to keep up with the demand for heat. A professional can help determine whether the unit requires heating or needs to be upgraded to a larger size.

Constant Cycling

A unit that continuously turns on and off, running for only a few seconds or minutes at a time, may have a clogged filter or a faulty thermostat. This can cause large increases in utility bills and waste resources. A technician can help diagnose and treat the problem.

Failure to Heat or In Spite of Cycling

Some models have a pilot light, and if the pilot light goes out, the furnace may cycle without burning fuel. Avoid this by placing the unit in an area free of drafts. Professional assistance is necessary if a pilot light has gone out in propane or natural gas HVAC systems because there is a risk of the fuel being released into the air. If there is an odor of rotten eggs, residents should leave immediately and call a heating repair specialist.

Regular maintenance and examinations by a qualified heating repair professional can help keep an HVAC system in top working order, saving time and money on replacement and repair costs. By replacing filters regularly and keeping vents clear of dust and debris, homeowners can help keep their energy costs down. Regular service by a professional will also reduce costs and extend the life of an HVAC unit.
