Our signature “Check & Clean” service is a comprehensive inspection and cleaning designed to boost system performance and prevent breakdowns. During your appointment, a DFH technician will:

• Inspect thermostats, electrical connections and system controls
• Clean condenser coils, blower motors and condensate drains
• Check and replace air filters

Routine service is essential to keeping your heating and cooling system running at its best. Here’s what you gain with every DFH Check & Clean:

• Lower energy bills
• Longer equipment lifespan
• Cleaner indoor air
• Fewer breakdowns

We recommend two visits per year:

• Spring: Prepares your air conditioning for summer
• Fall: Ensures your furnace is ready for winter

Scheduling ahead helps avoid last-minute emergency calls, and keeps you comfortable year-round.

While professional service is key, here are a few things you can do between Check & Clean visits. Check out our HVAC Troubleshooting Guide for more tips!
