Air Filters: The technician will check and replace the air filters if necessary. Homeowners are also advised on how often they should change the filters themselves, depending on the type of filter and household conditions (e.g., pets, allergies).

Checking System Controls

Ensuring that the system starts, operates, and shuts off properly is another crucial part of HVAC maintenance. The technician will check the system cycle and controls to make sure everything is operating safely and correctly. This includes verifying that the system starts up and shuts down in accordance with the thermostat’s settings without unusual noises or problems that might indicate a malfunction.

Assessing Refrigerant Levels

For cooling systems, checking the refrigerant level is essential. Too much or too little refrigerant can make your system less efficient, increase energy costs, and reduce the life of the equipment. The technician will check these levels and adjust them if necessary.

Safety Checks

HVAC units, especially those that involve combustion, can pose safety risks if not properly maintained. Technicians will perform checks on gas connections, gas pressure, burner combustion, and heat exchangers to ensure there are no leaks or other hazards that could pose risks to household safety.

Providing a Maintenance Report

At the end of the maintenance service, the technician should provide a detailed report that outlines what checks were performed, what repairs were made, and any recommendations for improving system performance or preventing future issues. This report can help you keep track of your system’s health and plan for any needed repairs or upgrades.

Upgrade Your Thermostat

Installing a programmable or smart thermostat can make a significant difference in your HVAC’s efficiency. These thermostats allow you to set temperatures for various times of the day and automatically lower or raise the temperature based on your daily schedule and preferences. For instance, you can set the thermostat to adjust the temperature when you are not home or at night, which reduces unnecessary heating and cooling and lowers your energy bills.

Smart thermostats offer even greater control and efficiency. They can learn your schedule and temperature preferences and adjust automatically. Additionally, many smart thermostats provide energy usage reports that can help you understand your consumption patterns and identify ways to save even more.
