Fantastic experience replacing our outdated gas furnace and water heater with a new heat pump system. The team was professional and efficient. The best part? We saved thousands thanks to the generous rebates available. This upgrade is definitely worth it.

Regular AC drain line cleaning is a simple way to prevent costly AC repairs and keep your system working properly.
August 26, 2025
An AC drain pan, also called a condensate drain pan, is a small but vital part of your cooling system. It collects the water that forms as your air conditioner removes humidity from the air and directs it away from your home. When it doesn’t work properly, you may face issues like leaks, mold, and even damage to your HVAC system—making it important to understand how it works and how to maintain it.
