Bob's Heating & Air Conditioning | Experienced HVAC Repair in Bothell, WA

In our Bothell climate, with varying pollen levels and occasional wildfire smoke, we generally recommend checking your filter monthly and replacing standard 1-inch filters every 30-90 days. If you have pets or allergies, you may need to change it more frequently. A clean filter is crucial for protecting your HVAC system, maintaining good indoor air quality, and keeping energy costs down.

This is a common issue in Bothell as temperatures drop. Often, it's due to a dirty outdoor coil restricting airflow, low refrigerant levels, or a failing reversing valve. It could also be normal frost buildup that the defrost cycle isn't clearing. We recommend scheduling a diagnostic visit. Our technicians will check these key components and perform any necessary cleaning or repairs to restore your system's efficiency.

Our comprehensive Bothell-area maintenance visit is designed to prevent the issues you're experiencing. We inspect electrical connections, check refrigerant levels, clean condenser and evaporator coils, lubricate moving parts, test system controls and safety devices, and of course, check and replace your air filter if needed. This proactive service helps catch small problems before they become costly repairs and keeps your system running at peak performance.
