Hot water isn’t something you think about, until it stops working. Whether you’re dealing with inconsistent temperatures, low water pressure, or no hot water at all, we can help.

Dry winter air is a problem all across St. Catharines, especially in tightly sealed homes or older homes around Glenridge and Lakeport. If you suffer from dry skin, static, or sinus issues, your humidifier might need service. We do humidifier maintenance and repairs to keep them working. We also install whole-house humidifiers that connect to your existing HVAC system to control indoor moisture, help your furniture last, and improve indoor air quality for your family.
Fresh air circulation is essential for a healthy home, especially in modern, well-insulated buildings. If your space feels stuffy or you’re dealing with stale air or humidity buildup, it might be time for an upgrade. Our team installs HRV and ERV systems that bring in fresh outdoor air while recovering heat or cooling from the air you’re already using. These systems are ideal for newer builds in areas like Port Weller or Secord Woods and help you maintain comfort, reduce moisture, and lower energy waste throughout the year.
