Heat Pump Replacement in Granite Bay, CA
Large Granite Bay homes need 4- to 5-ton units. Oversizing wastes money. Fresh Air runs a Manual J at every free estimate.

Granite Bay homes often exceed 3,000 square feet. A 3-ton unit will fall short in July heat. A 6-ton unit will short-cycle and fail to pull humidity. Fresh Air uses a Manual J load check to find your exact size. We have done 900+ installs since 2009 and hold CSLB license #945361.

Large jobs get milestone payment steps. You pay as each phase wraps. No large lump sum up front.
We protect finished floors and landscaping during install. Our crew works in clean booties and removes all debris the same day.
A unit too large for your home cools the air fast but runs in short bursts. Short cycles mean the unit never runs long enough to pull moisture from the air. Your home feels clammy even when it reads 74 degrees. Fresh Air's Manual J prevents this. We have sized and installed over 900 units across the Sacramento region.
California Title 24 requires a load calculation on permitted HVAC replacements. Our estimate includes this at no extra charge. We file the permit and coordinate the final inspection for you.
Your old unit may have been the wrong size. Home upgrades like new windows or added insulation also change the load. A Manual J confirms the right size for today's home.
Most homes in that range need 4 to 5 tons. The exact size depends on ceiling height, insulation, and window area. Our load check gives you the precise answer.
