Learning About HVAC Repairs

If your HVAC is not acting right, this can be due to a variety of issues. Below are three possible causes that can cause problems you should be aware of so that you can get your HVAC unit repaired and working right again.

Problems With Thermostats

In many cases, a problem with an HVAC unit is caused by the thermostat. There are two different types of thermostats, one that is programmable and one that is not. Check your thermostat to see if it is set to the right temperature, such as heat or cool, as well as if the temperature itself is set right. If so, then this is likely not your problem. 

If you don't have a programmable thermostat, now is a good time to look into one. A programmable thermostat is much better than one that you cannot program. For example, a programmable thermostat allows you to preset temperature settings. You can set it to automatically lower the temperature at night while you are sleeping. This will not only help you sleep better but will also cause your unit not to run as much. You could then have the thermostat set to turn the temperature up at a certain time in the morning.

Wear and Tear

An HVAC unit has many components inside that allow it to run correctly. Over time any of these components can get worn down. This includes small things like bearings and belts, which are easy to replace. Other larger problems could be with a compressor, condenser coil, fan, and many electrical components.

If your HVAC unit is getting old, you should have these components checked out by an HVAC contractor. In many cases, they will be able to repair your unit. If the problem is with more than one component or if it will cost you a lot of money to repair, you should consider replacing your unit with a new one. Newer HVAC units are more energy efficient and can help save you money each month.  

Strange Noises

If your HVAC unit is making strange noises in the winter months, there could be a problem with the heat pump. If so, you will hear a churning type of noise when the heat pump moves air between the refrigerant and the cooling and heating. As this air transfers, it should go smoothly, but if there is a problem with the heat pump, it will make noises during the air transfer. 

If you are hearing a loud sound that sounds like metal is hitting against metal, this is usually caused by the fan blades being bent or the blades could be hitting wires, tubing, or ice while they are spinning.
