Add Central AC or Replace Your Existing Air Conditioner
Whether you're installing central air conditioning for the first time or replacing an aging AC system, you may not need to replace your entire HVAC setup.

Maximum Comfort Heating & Air Conditioning can evaluate your existing equipment, recommend a compatible AC and coil installation, or help you compare complete AC and furnace replacements and all-electric heat pump options.

What Type of AC Installation Do You Actually Need?
A new air conditioner doesn't always require replacing the furnace, and a complete HVAC upgrade doesn't have to mean another gas system. We evaluate the entire setup first.
*Starting estimates are for qualifying installations, not guaranteed quotes. Actual costs depend on equipment, size, labor, permits and required changes. Prices do not include rebates or tax credits. For additions or spaces without ducts, consider our mini-split installation options .
When Is a New Air Conditioner Worth Considering?
One breakdown doesn't automatically mean you need a new AC. But replacement may be worth comparing when you face repeated repairs, a confirmed major component failure, persistent cooling problems, or equipment that no longer matches your comfort needs.
Repeated Repairs
Compare upcoming repair costs with the price and warranty coverage of new equipment.
Weak Cooling
Determine whether the issue is the AC, airflow or ductwork before deciding to replace.
Major Failure
A failed compressor or leaking coil can make replacement worth considering.
Changing Needs
Renovations or additions may change the home's cooling requirements.

Frequently Asked Questions About New AC Systems
Practical answers to common homeowner questions about central AC installation.
Can I replace my AC without replacing the furnace?
Often, yes. When your furnace, blower, controls and ductwork remain compatible and in good condition, we may replace the outdoor AC condenser and matching indoor coil while keeping the furnace.
What's included in an AC condenser and coil replacement?
The typical scope includes the outdoor condenser, compatible indoor evaporator coil, refrigerant connections, controls and drainage checks, startup and operating tests. Any additional work is confirmed in your proposal.
How much does central AC installation cost in San Diego?
A qualifying central AC condenser-and-coil installation may start around $8,000 when compatible existing heating equipment and ductwork can be retained.
Complete AC and gas-furnace replacements and qualifying central ducted heat pump installations may start around $12,000. Equipment upgrades and necessary modifications affect final pricing.
Read our AC installation cost guide for more information.
What's the difference between the five AC installation packages?
Basic and Silver use single-stage cooling with different labor coverage and service terms. Gold and Platinum use two-stage cooling, with Platinum including a longer service term.
Presidential adds variable-speed cooling and listed air-scrubber equipment. Final specifications and warranty details are confirmed in writing.
Should I replace my gas furnace and AC with a heat pump?
A ducted heat pump can provide heating and cooling through suitable existing ducts. It may be worth comparing when both the furnace and air conditioner are aging.
Learn about ducted heat pump installation .
Do I need new ductwork for a new air conditioner?
Not necessarily. Existing ducts may be reused when properly sized, sealed and compatible with the new equipment.
Maximum Comfort offers ductwork installation, repairs and sealing, but not professional duct cleaning.
Does an AC replacement require a permit in San Diego?
Many central AC replacements require a mechanical permit and applicable inspections. Requirements vary by jurisdiction, property and project scope.
Review the City of San Diego mechanical permit guidance .
What refrigerant will my new AC use?
Refrigerant depends on the approved equipment model. Many newer systems use R-454B or R-32, while older equipment may contain R-410A or R-22.
Refrigerants are not freely interchangeable. Equipment and servicing must follow manufacturer specifications.
How long does an AC installation usually take?
A straightforward condenser-and-coil replacement may take around a working day. Full-system replacements, duct modifications, or electrical upgrades may require more time.
Do you offer free estimates and financing?
Yes. Maximum Comfort offers free estimates for qualifying residential AC installations and replacements.
