FAQs
What types of heating and air-conditioning systems do you install in Monterey?
We specialize in high-efficiency forced-air furnaces, heat pumps, ductless mini-splits, and custom-designed hybrid systems that combine heating and cooling in one unit. Because Monterey has a temperate coastal climate, we focus on right-sizing equipment to maximize energy savings while ensuring year-round comfort.
How does the coastal Monterey climate affect my equipment choice?
Salt-laden ocean air can accelerate corrosion, so we recommend units with corrosion-resistant coatings, stainless-steel components, and sealed electronics. In addition, our mild winters and cool summers mean that properly matched variable-speed or inverter-driven systems often outperform traditional single-stage units, providing better humidity control and lower utility bills.
Do I need permits for a new HVAC installation in Monterey County?
Yes. The County of Monterey requires building permits for most HVAC replacements and all new installations. We handle the entire permitting process, including Title 24 energy compliance documentation and scheduling the final inspection, so you don’t have to worry about paperwork or code compliance.
How long does a custom HVAC installation usually take?
Most standard change-outs are completed in one day. However, custom projects—such as adding new ductwork, zoning, or converting from gas to an all-electric heat-pump system—typically take 2–4 days. We provide a detailed timeline in advance and coordinate with any other trades to minimize disruption.
What warranties and maintenance plans do you offer?
All of our installs include a 10-year manufacturer’s parts warranty and a 1-year labor warranty, which can be extended to 10 years with our Premium Protection Plan. We also offer annual maintenance agreements that include biannual tune-ups, priority scheduling, and discounts on any required repairs.
How much will a custom installation cost in the Monterey area?
Costs vary depending on system type, home size, duct condition, and any required electrical upgrades. As a rough guide, ductless mini-split installations start around $4,500 per zone, while whole-home heat-pump systems typically range from $12,000 to $18,000 fully installed. We provide free in-home assessments and firm written quotes so you’ll know the exact investment before any work begins.
