Knowing when you should call a heating repair contractor for help is an important way to keep your home warm during the colder months of the year. In fact, detecting and fixing heating issues early can save you money and hassle later. Before lower temperatures arrive, take the time to brush up on how to recognize the indicators that your heating system is no longer working properly. If you ever notice these warning signs, it's time to reach out to a heating repair service.
1) Your system is not producing the right amount of heat.
One of the most obvious signs that something is wrong with your heater is that the system is producing little to no heat. You'll notice that only cold air is blowing when you turn on the heater, or the heater won't start up at all. Additionally, you might see that your thermostat is turned up, but the temperature never actually rises. While the system could just require a quick fix such as a filter replacement, a heater that isn't sending out any hot air usually points to a bigger problem that needs to be handled as soon as possible. A professional heating contractor will be able to properly diagnose the root cause and know exactly what repairs are needed.
2) You hear loud or strange sounds from the heater.
Unexpected noises coming from your heater is definitely a cause for concern. A constant buzzing could indicate an electrical problem, and a loud pop or boom might mean that there is a malfunction with the heat exchanger. Listen for rattling or grinding too, as these noises could point to a loose or worn out part. If you hear a strange sound that you've never heard before or that starts suddenly, be sure to call an HVAC technician right away. Failure to promptly check into weird heating system sounds might lead to more extensive repairs in the future or exacerbate a dangerous safety hazard.
3) The heater is turning on and off too frequently.
In general, your heater should run for fifteen minutes or so until the desired temperature is reached and then turn off for a longer period. However, a heater that continues to cycle back on too often is a significant warning sign. This is called short-cycling, and it means that your heater isn't operating efficiently. It could be the result of a furnace that isn't the correct size for your home, or there might be restricted airflow somewhere in the system. If you find that the heater is cycling on and off several times in an hour, then you should call a heating contractor to investigate the problem.
When any of these signs occur with your heating system, be sure to reach out to an HVAC technician to get any repairs completed in a timely fashion.
