Fresh air
A tighter house needs a way to breathe.
New windows, insulation and air sealing keep heat in — and stale air, moisture and cooking smells too. An energy recovery ventilator swaps stale air for fresh, filtered air while holding on to most of the heat.
Questions we get asked.
What is an ERV?
An energy recovery ventilator. It brings in fresh, filtered outdoor air and sends stale indoor air out, passing heat between the two streams so little of it is lost. The air streams never mix.
Does my house need mechanical ventilation?
If it has been tightened up with new windows, insulation or air sealing, it may. Signs include condensation on windows and stuffy rooms in the morning. New homes in California already require it under Title 24.
Can you replace my gas furnace with a heat pump?
Yes. We size the heat pump with a load calculation, check the ducts and the electrical supply, and explain how it will run differently.
Do you work on offices and shops?
Yes. Rooftop and split systems, ventilation for meeting rooms, and maintenance plans with a short report per unit.
Is ColorNest an interior design company?
No. Interiors is part of the name. ColorNest does heating, ventilation and air conditioning only.
