How to Maintain Your Ductless Mini-Splits
Maintaining your ductless mini-split system is simple and helps it run efficiently for years to come. Start by regularly cleaning or replacing the air filters, as dirty filters can reduce air quality and strain the system. Keep the indoor unit free of dust and debris by gently wiping it down, and ensure the outdoor unit is clear of obstructions like leaves or dirt to allow proper airflow.

Lambert has been our plumber and HVAC professional since we bought our house 15 years ago. In that time, we have expanded and upgraded our equipment. I cannot recommend them more highly. They are problem solvers and go above and beyond expectations.

This company is great and does amazing work! We needed a new way to vent our older boiler and water heater before the freeze. We had no hot water or heat! Steve and Alex came out, talked through our needs, and set us up nicely.
