Spring HVAC Prep: Filters, Outdoor Unit, Thermostat

If you’ve recently been told by an HVAC expert or even just an acquaintance that spring HVAC maintenance is vital, they’re correct — but it’s important to understand why. As much as anything, spring HVAC maintenance appointments are about the upcoming summer more than the actual spring, as the former creates significantly more strain and demand on most HVAC setups. 

At Green Line Heating & Air, we’re happy to provide a wide range of heating and air conditioning services, from repairs and replacements of any components that require it to standard seasonal inspections of any system on behalf of our clients. Whether with the assistance of our technicians or even on your own for simpler areas, here are some tips we recommend on ensuring your HVAC system has been assessed after the winter and is prepared for the upcoming spring and summer.

Changing Filters

To be clear, changing your filters with the proper frequency is not something that’s exclusive to the springtime — it’s a year-round responsibility. However, during the springtime when many people are turning on their AC for the first time after months of disuse, it’s especially important to make sure you have a clean air filter in order to avoid any unnecessary strain on your system.

Failure to change your filters as needed (or worse, using a dirty filter) can decrease your system’s efficiency, cause dust and other allergens to accumulate inside your home, and even lead to early system failure.

Cleaning the Outdoor Unit

Just as you should clean the filters in your AC unit, it’s also important to clean the outdoor unit. This entails removing any debris (leaves, twigs, dirt, etc.) that may have built up over the winter.

Not only will cleaning the outdoor unit help your system run more efficiently, it’ll also make it look nicer aesthetically. And if you live in a hotter climate, keeping the outdoor unit clean can actually help improve the unit’s cooling performance.

Consider a Thermostat Upgrade

If your home is still using an older manual thermostat, it might be time to consider an upgrade to a programmable or smart thermostat.

Programmable thermostats allow you to set different temperatures for different times of the day (for example, you can have the AC running at a higher temperature when you’re away at work and lower when you’re home), while smart thermostats can be controlled both manually and remotely using a smartphone or other internet-connected device.

Installing a programmable or smart thermostat is a great way to save on energy costs, as they can help you keep your home at the ideal temperature for maximum comfort and efficiency.


These are just a few of the many things you can do during the early parts of spring, and part two of our series will cover even more. For more on this, or to schedule spring maintenance or learn about any of our other services, speak to the team at Green Line Heating & Air today.
