Your HVAC Questions, Answered

For most homes, we recommend changing your filters every 30 to 90 days. If you have pets or allergies, checking them monthly ensures your system maintains proper airflow and high indoor air quality.

Common warning signs include unusual noises (grinding or squealing), weak airflow, strange odors, or a sudden, unexplained spike in your monthly utility bills.

We recommend a professional tune-up twice a year: once in the spring for your AC and once in the fall for your heating system. This preventative maintenance extends the life of your equipment.

A frozen unit is usually caused by restricted airflow (dirty filters or blocked ducts) or low refrigerant levels. If you see ice, turn the system off immediately and call us to prevent compressor damage.

If your system is over 10-15 years old and requires frequent, costly repairs, a high-efficiency replacement is often more cost-effective in the long run due to energy savings and modern reliability.

Ductless mini-splits provide targeted cooling and heating to specific rooms without the need for ductwork. They are perfect for sunrooms, home offices, or older homes with limited space.

Installing a programmable thermostat, keeping your filters clean, and ensuring your ductwork is properly sealed can significantly lower your energy consumption during peak heat.
