HVAC Questions Answered

Frequently Asked Questions

Get answers to the most common questions about our HVAC services, equipment, and process.

We recommend servicing your HVAC system at least twice a year — once in the spring for your air conditioning and once in the fall for your heating system. Regular maintenance helps prevent unexpected breakdowns, keeps your energy bills low, and extends the life of your equipment.

Proper sizing depends on your home's square footage, insulation, window count, ceiling height, and other factors. An oversized or undersized system wastes energy and wears out faster. We perform a detailed Manual J load calculation during our free in-home estimate to recommend the right-sized system for your specific home.
