Homeowners should have their HVAC units inspected at least twice per year to maintain efficiency. If possible, you should have the unit inspected right before the heavy usage seasons come around.
Even though many people feel that the air filter is the main thing that needs to be inspected, there is a lot more than that to it. A number of things come into play that need to be inspected to maintain safety and efficiency.
Every spring or summer the condenser coil is inspected, which is a main component of the unit that can end up accumulating debris and dust. When the coils are dirty, it can restrict the abilities of the refrigerant to successfully transfer heat. You end up losing efficiency and the unit is forced to run harder and longer than what it needs to in the first place.
When it comes to the inspection before winter sets in, the most important things that need to be done to make sure the unit is safe is to check the combustion furnace. The technician will come in and check the heat exchanger containing the burners that is responsible for heating up the air that passes through it. As the exchanger heats up and cools down over the course of time, it contracts and expands. Most of the time, this is not an issue.
In some instances, it can cause a crack within the exchanger to developer. Cracked heat exchangers will decrease the performance of the furnace significantly. In the end, carbon monoxide can end up leaking into the home. These long-term safety issues can all be prevented by having a regular inspection of the unit.
Adopting a regular maintenance program will help to save a lot of money in the end by preventing costly breakdowns and lowering the cost of your energy bill. Since an air conditioner will run throughout the day for the duration of the summer, regular maintenance and cleaning can help to reduce the energy bill dramatically. Something minor can make a world of difference on your energy bill every month. A regular inspection will let you know of any potential issues before they spiral out of control into something costly.
