How to Avoid Costly HVAC Repairs

As the weather starts to cool down, homeowners all around the Lowcountry begin to prepare for fall and the cooler weather that is coming. As we all know, our HVAC units have been working hard all summer, so it’s important to perform preventative maintenance to avoid costly repairs down the line. Read on for tips on the best ways to ensure a bigger issue doesn’t happen, causing stress and creating a potentially costly repair.


Easiest tip in the book, but it doesn’t go without saying. Regularly changing your air filters leads to better airflow and circulation and helps your machine function.


The compressor’s job is to blow hot air outside; because it is open, it’s likely to pick up dirt and other particles or debris. These could impact the way your machine runs, and it’s important that these stay clean. Our trained technicians can turn off the system and ensure that your lines are clear.


At the end of a long summer, it’s important to keep your drain lines clean. The air conditioner takes moisture from your home and collects it in drain lines. They collect moisture over time and can easily get clogged. To avoid accidents, it’s important to keep these clean, and our technicians can do them easily and quickly without making a mess. 


Being outside and exposed to heat, sun and elements, your HVAC machine can take a beating. Over time, rainfall, humidity, bright sunlight and even bugs can cause issues. It’s not too difficult, but keeping your unit clean is a bit messy, and our team can help you get your spic and span in no time.


Now that the weather is getting colder, a heating tune-up is in order. Overall, your system operates better when it is kept clean and well-maintained. When there is a build-up of excess dust, pet dander, pollen and other debris, it can obstruct airflow and decrease efficiency. That’s why at Blanton and Sons, we recommend scheduling a heating tune-up as the most important task on your fall homeowners to-do list. It leads to better efficiency of your unit and better performance, not to mention overall better quality of life for you and your family.

When your heater runs well, it will keep your home warm while using less energy. And less energy usage means lower energy bills. Also, when your unit is kept in better working order, it means overall there’s less wear and tear while will help prolong its lifespan, especially when coupled with yearly tune-ups. 

We do recommend a tune-up every fall and one in the spring too for homes with a heat pump since it’s being used to cool your home too.
