HVAC Installation & System Replacement in Sacramento & Carmichael
Full HVAC system installation and replacement for central AC, furnaces, and heat pumps across the Sacramento area. Proper sizing, licensed installation, 180-day warranty on all labor — done right the first time.

PRO MAX delivers full HVAC system installation and replacement for central AC, furnaces, and heat pumps across the Sacramento area — proper sizing, licensed installation, and a 180-day warranty on all labor.
Overview
When an HVAC system reaches the end of its service life — or when repair costs exceed the economic value of the equipment — a full system replacement is the right move. In the Sacramento Valley, where a working central air conditioner is a practical necessity for five or more months of the year, making the right equipment choice and having it installed correctly are decisions that affect your household's comfort and energy costs for the next 15 to 20 years.
PRO MAX HVAC & Appliance Repair installs complete residential HVAC systems throughout Carmichael, Sacramento, Roseville, Citrus Heights, Folsom, Elk Grove, and surrounding communities. We replace central AC systems, gas furnaces, heat pumps, air handlers, and evaporator coils — individually or as complete matched systems. Every installation is properly sized using Manual J load calculations, permitted, and backed by our 180-day labor warranty plus manufacturer equipment warranties.
Sacramento's climate makes proper sizing especially important. An oversized system that cools too quickly without running long enough to dehumidify creates a clammy, uncomfortable home during the Sacramento summer's monsoon weeks. An undersized system runs continuously in July heat without reaching setpoint. We size systems correctly and explain the rationale so you understand what you are getting and why.

Our Installation Process
- Site assessment and proposal — We assess your existing system, ductwork condition, and home characteristics. We perform a Manual J load calculation and provide a detailed proposal covering equipment options, sizing, and all labor.
- Permit acquisition — We handle all mechanical permit applications. No unpermitted work.
- Installation day — Our crew removes the old equipment, installs the new system, makes all refrigerant, electrical, and ductwork connections, and cleans up completely.
- Commissioning and testing — We charge the refrigerant system to manufacturer specifications, test all operating modes, verify airflow, and confirm the system performs as designed.
- Training and documentation — We walk you through thermostat operation, filter maintenance, and warranty documentation. We assist with manufacturer warranty registration on your behalf.
Warranty & Guarantee
PRO MAX backs all HVAC installation labor with a 180-day warranty. Equipment manufacturer warranties — typically 5 to 10 years on parts, 10 years on compressors for registered equipment — begin from the installation date. We assist with manufacturer registration as part of the installation.
Why Sacramento Residents Rely on PRO MAX
HVAC installation quality determines how well a system performs and how long it lasts. An improperly sized system, incorrect refrigerant charge, or inadequate ductwork modification can undermine even a premium piece of equipment. We invest in getting the sizing, installation, and commissioning right because our 180-day labor warranty is on the line — and because our reputation in the Sacramento area depends on systems that perform as promised.
We are also straightforward about the repair vs. replace decision. When a repair makes economic sense, we say so and perform the repair. When it does not, we explain why and provide honest replacement options. We do not recommend replacement when repair is the right call.
HVAC Installation & System Replacement — Frequently Asked Questions
A complete central AC and furnace system replacement in Sacramento typically runs $7,000 to $15,000 installed, depending on system size, efficiency rating, brand, and the condition of the existing ductwork. Heat pump systems are in a similar range. High-efficiency variable-speed systems are at the upper end. We provide a detailed proposal after a site assessment.
For most Sacramento homes, central AC with a gas furnace remains the most common setup — it handles extreme summers effectively and the mild winters don't challenge it. Heat pumps are an increasingly strong choice, particularly variable-speed inverter-driven units that are highly efficient in our climate's moderate heating conditions and pair well with solar systems. We discuss the options for your specific home and situation.
Proper sizing requires a Manual J load calculation that accounts for square footage, ceiling height, insulation R-values, window area and orientation, duct condition, and local climate data. Sacramento's design temperature of around 105°F in summer drives sizing more than the mild winter heating load. Oversizing is a common mistake — an oversized AC short-cycles, creates humidity problems, and wears out faster.
A standard central AC and furnace replacement typically takes one full day. If ductwork repairs or modifications are needed, the project may extend to two days. We assess the site before scheduling to give you an accurate timeline.
Yes — mechanical permits are required for HVAC system installation throughout Sacramento County and most incorporated cities in the area. We handle all permitting as part of the installation and coordinate the required inspection. Any contractor who skips permits is exposing you to significant liability.
