FAQ

“HVAC” stands for Heating, Ventilation, and Air Conditioning. It describes the systems and components that control temperature, airflow, and indoor comfort. At Air Tech Heating & Air Conditioning Service Co, we service furnaces, heat pumps, ductless systems, central AC, ventilation systems, and more.

We recommend servicing your HVAC system twice per year—once before cooling season and once before heating season to optimize performance, prevent failures, and maintain warranties.

While scheduling depends on demand, we prioritize emergency service calls. Our local presence means that we can often respond the same day or as quickly as possible to restore your comfort.

Absolutely. Preventive maintenance reduces energy consumption, catches small issues before they become major repairs, and helps extend your system’s life, all of which add up to cost savings.

With proper care, modern HVAC systems typically last 15 to 25 years, depending on usage, climate, and maintenance history.

Consider replacement if your system is over 10–15 years old, requires frequent repairs, uses outdated refrigerants, or operates inefficiently. We’ll provide an honest assessment and comparison when we inspect your system.

In most homes, changing the filter every 2 to 3 months is ideal, and more frequently if you have pets, allergies, or heavy use in summer/winter. Clean filters improve airflow and system efficiency.

There are a few ways to reduce energy costs. We recommend:

• Optimize system sizing and ductwork
