Heating, Ventilation & Air Conditioning FAQs

Q: How often should I schedule HVAC maintenance?

We recommend servicing your heating and cooling system twice a year-once during the cooling season and once during the heating season. Regular maintenance helps extend the life of your equipment, improve efficiency, and lower energy costs. It’s also often required by manufacturers to keep your warranty valid.

For a worry-free experience, ask us about our Comfort Club-a maintenance plan designed to keep your system running smoothly all year long!

If your system is more than 12-15 years old, breaking down frequently, or driving up energy bills, it may be more cost-effective to replace it. We offer honest assessments and can help you weigh your options.
