Preventative maintenance, such as changing filters and scheduling annual tune-ups, ensures your A/C operates efficiently and reduces the risk of breakdowns during heat waves.

Routine HVAC maintenance should be scheduled twice a year to keep your system running safely and efficiently. Your furnace should be serviced once every fall before heating season, and your air conditioner should be serviced once every spring before cooling season. This helps prevent breakdowns, improves energy efficiency, and extends the life of your equipment. Many manufacturers also require annual maintenance to keep warranties valid.

Most HVAC systems need a new air filter every 1 to 3 months, depending on the type of filter and conditions inside the home. Standard 1‑inch filters usually need the most frequent replacement, while thicker high‑efficiency filters can last longer. Homes with pets, allergies, construction dust, or higher system usage may need more frequent changes. Keeping a clean filter in place protects airflow, reduces strain on the blower motor, and helps maintain proper heating and cooling performance throughout the year.
