HVAC Replacement FAQs

With proper maintenance, the life span of an air conditioner is about 15 years. Furnaces tend to last closer to 20 years. It might be time for a new HVAC system if your older unit is facing a costly repair, your energy bills are on the rise, or you’re experiencing significant comfort issues.

Sometimes. However, if your cooling system runs on an older type of refrigerant called R-22 (Freon), it won’t work with new R-410A (Puron) equipment. Even if the two components are compatible, a mismatched system could reduce performance dramatically, resulting in higher energy bills. That’s why we recommend replacing all parts of your HVAC system at the same time.

Indoor Air Quality FAQs

Humidifiers and dehumidifiers help maintain the ideal relative humidity level in every season. We suggest using whole-house models to maximize the benefits in every room. Let our experts assess your situation and recommend the best products to fit your needs.

The filter should be replaced once it appears dirty or clogged. For many homes, this is typically every 30 to 90 days. If you smoke, have pets, or suffer from severe allergies, you may want to replace the filter more often.
