Expect a Higher Level of Service

With winter fast approaching, you are going to rely on your heating more and more. When the heater falls short, even the Vegas winter temperatures can be a challenge to withstand. With routine professional maintenance services you can minimize the need for repairs and when repairs are needed being proactive and calling professionals at the first sign of trouble can help you avoid major problems. Below you will find a few of the most common problems that lead to having your heat repaired.

Furnace Troubleshooting

  • Pilot control or electric ignition problems: Making it difficult to heat a home or commercial space, a faulty ignition or pilot could be an indication there could be drafts or clogs in the appliance or thermocouple issues.
  • Faulty thermostat: A thermostat that is malfunctioning often results in the fan or comfort levels.
  • Furnace is inoperable: The thermostat setting, power, gas or the pilot light are experiencing problems.
  • Furnace isn’t sufficiently heating: A furnace may not produce enough heat if it’s the wrong size for the space or even the filter is clogged.
  • Frequent cycling: Improper airflow or a bad thermostat setting manifests when the cycling between the “On” and “Off” modes as well as a clogged filter.
  • Blower continuously runs: Only rectified with professional replacement, blower issues are often an issue with the limit switch.
  • Furnace is abnormally noisy: Rumbling, squeaking and rattles aren’t normal and the loud sounds point to a mechanical problem, airflow reductions, or a clogged burner.
  • Maintenance neglect: Failing to invest in scheduled annual furnace maintenance and inspections will often lead to unexpected problems and breakdowns. These routine inspections can help the appliance run more efficiently and reliably and can prevent many problems from arising.
  • Dirty filters: A clogged filter, under the right circumstances, may damage the limit switch, which controls the fan. Additionally, a dirty or clogged air filters reduce airflow, making a furnace work harder to circulate.
  • Wear and tear: Heat control-related problems or even overheating because of the normal wear and tear, can also contribute to airflow problems.

Tips to Avoid Furnace Heating Problems

  • Check the thermostat: If the heat is not in full operation, check the thermostat; start at the battery, it may need nothing more than replacing. If the blower fan doesn’t flip off or the furnace is cycling too frequently, inspect the thermostat’s settings; it should be set to “Auto.” In the “On,” “Low,” “Medium” or “High” modes, the fan will run continuously. Also make sure the thermostats are on “Heat” mode. Finally, check the temperature to make sure it’s set to one that’s higher than the current room temperature. If the problem is still not rectified, contact a pro.
  • Change the air filters: Dirty filters cannot permit proper airflow, not to mention that filthy filters drop the indoor air quality. To ensure everything runs properly, the filters should be checked once a month and changed when they show the need.
  • Furnace maintenance: When it comes to proper maintenance, ideally the heating should maintain by a professional at the end of the season, a tune-up service should be conducted at the start of every season and scheduling an inspection in between is ideal. With a professional performing these services, many issues can be avoided and the need for repairs minimized.
