Passive House Consulting

Passive building is the best path to Net Zero and Net Positive buildings because it minimizes the load that renewables are required to provide

Design Principles:

  • Proper insulation through the entire envelope without thermal bridging
  • Airtight building envelope
  • Continuous mechanical ventilation of fresh filtered air assures superb, healthy and controlled air
  • High performance windows and doors
  • Balanced heat- and moisture-recovery ventilation, using minimal space conditioning system
  • Solar gain managed to exploit sun’s energy
  • Extremely resilient buildings

It’s a building standard, not a technique


Architecture is not limited by Passive House design principles. There is as much variety in Passive House architecture as in conventional building. Passive House standards also seek to strike a healthy balance between up front building costs and long-term energy savings



Sustainable building standard, reduces energy consumption – saves money

Passive House Cost Savings GraphPassive House uses 90% less in heating and cooling energy and 70% less in total energy use of the building compared to conventional building.

Passive House’s sustainable building standard minimizes load renewables are required to provide.

Building standard actually reduces energy consumption, rather than just offsetting energy use through renewables.







Solar Installation

Are you looking to reduce your energy footprint through installing solar panels at your home or business? Harmony Air specializes in affordable grid tie-in and off-grid solar photovoltaic (pv) systems, as well as solar hot water systems for your home or pool.

Save Money While Helping the Planet

Solar energy is an eco-friendly alternative to traditional utilities; but did you know that a solar electric system could actually save you money on an ongoing basis? When your solar energy setup produces more electricity than you use on a monthly basis, that electricity is actually sent back to the grid. And when that happens, the power company has to pay you! In California, the average savings for each residential solar customer’s utility bill is $130 per month.

Tailored Systems Balance Quality with Affordability

Our high quality solar panels are capable of tapping into the limitless energy from the sun’s rays and generating high amounts of electricity for your property. This, in turn, will dramatically lower your utility bills and help you save a considerable amount of money down the line. We go out of our way to make sure that our installation services are tailored to your needs and are affordable. Every solar system we install is designed to reach its highest possible potential in return on investment, energy production, and reduction of carbon footprint.

Solar Hot Water

We also install solar hot water systems. Solar hot water heaters use the solar energy from the sun to generate heat (not electricity) which can then be used to heat water for showering, space heating, industrial processes or even solar cooling.

“Amazing! Amazing! Amazing! Sasha did our solar power, very clean, organized, and honest. Very easy to work with. I had talked to a few other companies about the solar project, they made it seem like they were going to build a rocket ship. When I finally contacted Harmony Air, Sasha explained everything step-by-step and made everything seem like a walk in the park. I know there is no job too big nor too small for Sasha and his crew. THANK YOU HARMONY AIR!!”

Heating, Ventilation and Air Conditioning (HVAC)

Harmony Air has been installing energy efficient heating, ventilation and air conditioning systems since 1991. That’s how our business got our start. We were the first company in Lake County to specialize in the environmentally friendly ductless mini-split systems by Fujitsu, Mitsubishi and Daikin. We also install traditional ducted systems as well.  Please contact us for a free consultation and a competitive rate.
