Whole-Home Air Comfort & Quality

At Harrex Electrical, we go beyond basic ventilation, we design and install complete air comfort solutions that keep your home healthier, drier and more comfortable all year round. That includes DVS home ventilation systems as well as Mitsubishi Electric HVAC — heating, cooling and fresh-air integration.

Whether you’re struggling with condensation and moisture, want better air circulation, or need a reliable heating/cooling system that works with your ventilation, we’ve got the right solution for Otago homes.

Why Choose DVS & Mitsubishi HVAC Together

Balanced Ventilation & Air Quality

Continuous ventilation is essential in modern homes. A DVS ventilation system pulls in fresh, filtered air while managing moisture and stale indoor air - helping reduce condensation, mould and allergy triggers.

For those wanting advanced ventilation performance, we also work with Mitsubishi Electric Lossnay fresh-air systems, which recover heat from outgoing air and use it to precondition incoming air, boosting efficiency and comfort.

Comfortable Heating & Cooling

Mitsubishi Electric HVAC systems are renowned globally for dependable performance, energy efficiency, and quiet operation — ideal for New Zealand’s varied climate. Their range includes heat pumps and integrated heating/cooling solutions that match your lifestyle or project needs.

Pairing these with a ventilation system means:

  • Fresh, filtered air year-round

  • Reduced moisture and condensation

  • Lower heating or cooling costs

  • Improved indoor comfort and wellbeing

We Install & Integrate Systems That Deliver
