Your HVAC unit has several functions in your home: heating, air conditioning and ventilation. As the seasons change, different parts direct it to work in different ways to keep your home comfortable. Some components, however, may start acting up when you least expect it. Here are four components that are most likely to break down and how to prevent problems.
The Thermostat
The first component you need to keep an eye on is the thermostat. The thermostat is what ultimately controls how your HVAC works. However, a malfunctioning thermostat can cause the HVAC unit to run incessantly. This can cause the price of your utility bill to increase as well as reduce the life expectancy of the HVAC. Fortunately, there are some signs to watch for that point to a broken thermostat.
Your thermostat may reflect inaccurate temperature readings or may remain blank. You also might notice that the temperatures remain constant even when you set it to change or that the heater or AC doesn’t turn off even when the house has reached its desired temperature.
The best way to keep your thermostat in good condition is with preventative HVAC maintenance. If your thermostat isn't functioning at all, an experienced professional can easily replace it with a new one.
The Air Filter
You’d be amazed at how many problems can arise from something as simple as a dirty filter. Mild problems include reduced airflow while more severe issues can be along the lines of damaging the heat exchanger. The indoor air quality of your home may suffer if allergens aren't removed. You should always swap out filters within or after three months. This will increase or decrease depending on how many people live in your home and if you have any furry pets.
The Evaporator Coil
The cool air that flows through your home is thanks to the evaporator coil. The evaporator coil is what soaks in all the heat from the air and works in tandem with another component called the condenser to produce cool air. When the evaporator coil is damaged in any way, you’ll notice pretty quickly.
Like the thermostat, there are various signs to look out for if there is an issue with the evaporator coil. The most noticeable sign is setting the thermostat to a low temperature and still getting hot air blowing through the vents.
The Heat Exchanger
The heat exchanger is the component responsible for transporting heat from location to location. If it malfunctions, you may start smelling strange odors, and dust may accumulate in your home. Keep in mind that if a faulty heat exchanger warrants immediate attention. Without repair or replacement, your HVAC can malfunction entirely.
The best way to prevent any of these issues is with regular preventative HVAC maintenance. When you get regular maintenance done, your HVAC professional will often be able to notice damaged parts before they actually start to affect the comfort of your home. These repairs will also be more affordable than they would be if you needed emergency repairs.
With proper maintenance, you can extend the life of your HVAC. Plan on seasonal maintenance, before and after the summer season to keep your system running all year long.
