Ducted Minisplits in Conditioned Attics: Duct Design and Performance Testing

Installing a ducted minisplit system in a conditioned attic offers an excellent way to heat and cool a home while keeping mechanical equipment inside the thermal envelope. Unlike ductless wall-mounted units, ducted minisplits use a central air handler hidden in attic space to distribute conditioned air through a network of supply and return ducts. This […]

Roof Protection for a Minisplit Outdoor Unit: Essential Shelter for Your Heat Pump

When you install a ductless mini-split heat pump system, the outdoor condenser unit often ends up sitting on a ground pad or wall bracket fully exposed to the elements. Most contractors will tell you that these units are designed to be weatherproof and do not require additional shelter. While that statement is technically accurate, it

Three Practical Methods to Test Whether Your Dehumidifier Is Performing Properly

When indoor humidity climbs above recommended levels, a dehumidifier is one of the most effective tools for restoring comfort and protecting your home. But how do you know if your unit is actually delivering the performance it claims? Understanding how a dehumidifier works and why your home may need one provides useful background, but verifying

Reducing Refrigerant Leaks from Heat Pumps: Essential Testing Strategies for Installers

Refrigerant leaks are among the most frequent sources of service callbacks for inverter-driven heat pump systems, and they carry consequences that go far beyond an uncomfortable building. When a system loses refrigerant, homeowners may notice inadequate heating or cooling, error codes and intermittent lockouts, ice buildup on indoor or outdoor coils, and unexpectedly high energy

Why Balanced Ventilation Systems Are Becoming a Mandatory Code Requirement

The way fresh air enters and leaves a home has long been an afterthought in residential construction, but that is changing rapidly. Building codes across North America are beginning to treat ventilation not as an optional upgrade but as a fundamental requirement. At the center of this shift is balanced ventilation, a system that controls

HVAC Return Pathway Options for Balanced Forced-Air Systems

When a forced-air HVAC system delivers conditioned air into a room but lacks an adequate path for that air to return to the central unit, the result is pressure imbalance. Some rooms become pressurized while others become depressurized, leading to comfort issues, moisture problems, and even combustion safety concerns in homes with fuel-burning appliances. Proper
