Frequently Asked Questions
How often should I schedule HVAC maintenance?
Ideally, you should schedule HVAC maintenance twice a year—once in the spring for cooling and once in the fall for heating. Regular check-ups help ensure optimal performance and catch potential issues before they become costly repairs.
What does a typical HVAC maintenance service include?
Maintenance usually includes filter replacement, thermostat calibration, refrigerant level check, coil cleaning, and inspection of electrical connections. Technicians also check for any signs of wear or needed repairs to keep the system running efficiently.
How can regular maintenance improve my energy bills?
Well-maintained HVAC systems run more efficiently, meaning they use less energy to heat or cool your space. This can lead to lower energy bills and a longer lifespan for your equipment, ultimately saving you money over time.
Will regular maintenance prevent all breakdowns?
While regular maintenance significantly reduces the likelihood of breakdowns by identifying issues early, it can’t prevent every possible failure. However, it does improve system reliability and reduces the chances of unexpected issues.
How long does a maintenance appointment take?
Most maintenance appointments take about 1-2 hours, depending on the size of the system and the complexity of the inspection. The time spent ensures thorough checks and adjustments to keep your system performing at its best.
