A Look at an HVAC Technician’s Tune-Up Checklist

air-conditioning-maintenanceAn air conditioning system is a carefully tuned machine that’s expected to work flawlessly through the hottest months of the year. Unfortunately, we can’t always expect machines to work without the occasional tune-up. After all, it’s a well-accepted fact that cars need maintenance to keep running smoothly for years and years to come.

However, many homeowners aren’t always ready to accept this, wondering if they can skip the maintenance or just do some occasional DIY work on the machine.

To help clear the air, we’ve decided to show you just a few tasks that make up an HVAC technician’s maintenance checklist.

Clean Indoor Coil: The indoor coil, also known as the evaporator coil, helps cool the air. These can get dirty over time (especially if the air filter hasn’t been replaced). If left uncleaned, it can freeze over and block cool air from being distributed through the ducts. Frozen coils will prevent the home from being cooled and also contribute to higher energy bills.

Check Wire Connections: Not every AC problem is due to a broken or dirty component. Sometimes, the problem could be as simple as a broken electrical connection. Wiring issues can happen between the thermostat and the air handler, outdoors near the condenser, and in several other places.

Check Refrigerant Pressures and Temperatures: Refrigerant is crucial for your AC to function properly. During the operation of your AC, refrigerant is condensed and evaporated repeatedly through a cycle. Maintaining the correct pressures and temperatures is necessary for ensuring that this process occurs without a hitch.

Visually Check for Refrigerant Leaks: Again, refrigerant is crucial. If refrigerant starts leaking, it means that your AC is on its way toward breaking down. The actual leaks are very small and hard to see. Instead, HVAC technicians check for “champagne leaks,” which are indicated by tiny bubbles. Newly formed leaks might not make any noise or make themselves apparent, so it’s crucial to have your lines checked during routine maintenance.

Test System for Carbon Monoxide Leaks: Carbon monoxide is a tasteless, odorless, highly poisonous gas. To keep you and your family safe, testing for carbon monoxide in your system is mandatory.

Check Thermostat Calibration: The settings on your thermostat will determine how hard your AC has to work. If there’s a malfunction with the thermostat, it will affect the performance of your system, possibly leading to increased energy bill costs.

Remove Debris from Outdoor Unit: A simple job, but one that is very necessary and easily forgotten. Debris in the outdoor unit can lead to overheating. Combined with the summer heat, a dirty outdoor unit is just asking for trouble.

Inspect Duct Connections: The ducts are responsible for dispersing air throughout your home, taking in the warm air and dispersing the cool air. If there are any leaks or disconnects in the ductwork, you can expect your AC to have problems cooling your home.
