A couple of months ago, the HVAC unit in my home started malfunctioning. The temperature inside my home soared to over eighty degrees Fahrenheit, even though my air conditioning system ran nonstop. After inspecting my air conditioning unit, my knowledgeable HVAC contractor recommended I purchase a new system. He discussed the pros and cons of installing different sizes of HVAC units with me. After considering my HVAC contractor’s advice, I decided to purchase a three and a half ton HVAC unit. Shortly after my HVAC contractor installed my new air conditioning unit, my house started feeling more comfortable. On this blog, I hope you will discover how an HVAC contractor can help you select the right air conditioning unit for your home. Enjoy!
If you rely on a furnace to heat your home, you might find it alarming if it suddenly stops working. You might fear that it is never going to work again and ponder over whether you will need to replace it. There are a number of reasons why furnaces may not heat. Sometimes the issue is not even related to the furnace but rather another portion of the heating system. Furnaces that have not been properly maintained are subject to mechanical failure and may abruptly stop working. Use the following points as a guideline for reasons your furnace may stop working.
It Isn't On
It is possible for there not to be any issues with the furnace other than the on and off switch not being in the correct position. Some furnaces have a switch that must be switched in the on position in order for them to work. The switch is usually located near the furnace. Sometimes the issue is related to a tripped circuit breaker. It is worth your time to check these things to ensure that they are not the problem.
Dirty Air Filter
Filters are designed to trap foreign substances such as dust. If they are not changed regularly, they get clogged with these substances. Clogged filters impede air circulation. Furnaces may respond by not working. Some furnaces are designed with this as a safety feature because dirty filters can cause furnace fires.
Thermostat
The thermostat could be set at the wrong setting. Try adjusting the temperature by raising it up. You should also check the thermostat batteries and replace them to see if the heat starts to work. If these actions do not cause the furnace to turn on, you might need to get a thermostat replacement, or the issue might be related to something else.
Pilot Light
A blown pilot light means that your furnace will not produce heat. An HVAC contractor can relight the pilot light and determine if there are issues such as a drafty area where the furnace is located that caused the pilot light to go out.
Water Leak
If you have a condensing furnace, your furnace could stop working due to a leak or a condensate pump issue. Check around the furnace to see if you notice water. This is an issue that will require professional repair.
A furnace that stops working in the winter can be considered an emergency. An HVAC contractor is a good resource to use to determine the cause of the issue. Most of them offer 24-hour emergency HVAC services. Contact a company like Bud's Plumbing, Heating, Air Conditioning & Electric to learn more.
