Maximum Comfort Heating & Air Conditioning
Real Projects. Real Workmanship.
From residential AC replacements to large commercial installations, here's a look at heating and cooling projects completed by Maximum Comfort.
These are actual job photos showing the equipment, installations, and people behind our work. No stock-photo showroom.
AC Replacement in San Diego
Replacing older equipment can make a big visual difference, but the most important work goes beyond what you can see outside the home.
BEFORE AFTER Out With the Old. In With the New.
This project shows an aging outdoor HVAC system before replacement and the newly installed equipment afterward.
The outdoor unit may be the most recognizable part of an installation, but system compatibility, refrigerant connections, electrical work, and commissioning are equally important.

More Residential Heating & Cooling Projects
From rooftop equipment to indoor furnaces and ductwork, each project has its own installation requirements.
Rooftop HVAC York Rooftop HVAC Installation
Our team worked on a rooftop HVAC installation in La Mesa featuring York equipment.
Rooftop work requires planning for equipment access, positioning, mechanical connections, and safe installation.
HVAC & Ductwork HVAC Replacement & Ductwork
This La Jolla project involved HVAC equipment replacement together with ductwork and related system components.
It's an example of how residential HVAC work extends beyond the outdoor equipment. Air distribution, indoor equipment, and controls are all part of the system.
Residential HVAC York HVAC System Installation
Our Allied Gardens project documents outdoor HVAC equipment and several stages of the installation.
These photos provide a closer look at the equipment and work involved before a finished system is ready for use.
Indoor HVAC Indoor Equipment & Heating Work
Not all HVAC work happens outside. Indoor equipment, heating components, and connections also require careful installation.
This additional La Jolla photo highlights gas furnace equipment and the type of work homeowners don't usually see once an installation is complete.
We offer furnace replacement and installation estimates for qualifying residential projects.
Gas Furnace Replacement in Point Loma
Outdoor AC units get plenty of attention, but a furnace replacement can involve just as much care in a much tighter space.
BEFORE AFTER A New Furnace in an Existing Space
For this Point Loma project, Maximum Comfort replaced the existing gas furnace with new heating equipment.
Installation work in a furnace closet requires attention to equipment dimensions, access, venting, and connections.
A new furnace also needs to be compatible with the home's existing heating and air-distribution requirements.

Commercial HVAC Installation in Pine Valley, CA
Pine Valley, California · Large-Capacity Packaged HVAC Equipment
Maximum Comfort completed a commercial HVAC installation involving large-capacity packaged equipment. The project included approximately 25-ton packaged HVAC equipment serving a gym and additional buildings.
Larger commercial installations require careful planning for equipment access, placement, mechanical connections, and the needs of the spaces being conditioned.
These photographs highlight the scale of equipment and work involved in a project that's quite different from a typical residential replacement.
Commercial HVAC work can involve substantially different equipment, coordination, and installation requirements than residential systems.
Equipment requirements vary by building and project. Referenced capacities describe the reported installation work, not necessarily the capacity of every pictured unit.
From Mini-Splits to Heat Pumps & Package Units
Different homes and properties call for different heating and cooling solutions. Here are three more examples from around San Diego County.
Ductless Mini-Split Installation
A ductless mini-split installation in Del Mar. These systems can offer targeted heating and cooling without conventional ductwork.
Packaged HVAC Unit
Packaged HVAC systems combine major heating and cooling components in one cabinet. This project highlights packaged equipment in Otay Ranch.
Heat Pump Installation
A residential heat pump installation in Poway. Heat pumps provide both heating and cooling and can be used with suitable ducted system designs.
Good HVAC Work Is About More Than the Equipment
An attractive new outdoor unit is great, but installation quality and system compatibility matter just as much as the brand.
Thoughtful System Selection
Equipment needs to match the home's heating and cooling requirements, electrical capabilities, and existing system design.
Professional Installation
Airflow, refrigerant piping, drainage, wiring, equipment placement, and startup procedures all contribute to reliable performance.

Frequently Asked Questions About HVAC Installation Projects
Seeing completed projects can help you visualize an installation, but every home has its own equipment, pricing, and permit requirements.
How much does a new AC installation cost in San Diego?
At Maximum Comfort, a standard 2-ton central AC condenser-and-coil installation starts around $8,200 when compatible existing heating equipment and ductwork can be retained.
Larger systems, higher-efficiency equipment, ductwork modifications, or complete system replacements may cost more.
Read our San Diego AC installation cost guide for more details.
Do I need a permit to replace my air conditioner or furnace in San Diego?
Generally, yes. The City of San Diego requires mechanical permits for many HVAC installations and replacements, including central AC, furnaces, heat pumps, and mini-splits.
Some straightforward residential projects may qualify for a simplified mechanical permit, while more complex installations or certain properties may require additional review and plans.
Permit requirements can vary by jurisdiction, property type, and scope of work. We'll discuss applicable requirements during your installation estimate.
Learn more from the City of San Diego Development Services Department .
Can I replace my gas furnace and AC with an electric heat pump?
Yes. Many homes can transition from a gas furnace and conventional AC to an all-electric ducted heat pump system.
A ducted heat pump provides heating and cooling through the home's air distribution system. You do not necessarily need wall-mounted mini-split units to switch to a heat pump.
Existing ducts may be reusable when properly sized and in suitable condition. Electrical and equipment compatibility must also be evaluated.

How long does an HVAC installation take?
A straightforward central AC replacement, furnace replacement, or single-zone mini-split installation may take approximately half a day to one full working day.
More extensive projects, including complete HVAC conversions, new ductwork, multi-zone systems, or electrical modifications, may take several days.
Some installations can take up to five working days or longer, depending on the scope. Permitting, inspections, and scheduling may affect the overall timeline.
Do I need new ductwork when replacing my HVAC system?
Not necessarily. Existing ductwork can often be reused when it is properly sized, sealed, and compatible with the new equipment.
Damaged ducts, significant air leaks, poor airflow, or inadequate return capacity may justify repairs or replacement.
Maximum Comfort provides ductwork installation, modifications, sealing, and repair. We do not offer professional duct cleaning.
What refrigerant will my new AC or heat pump use?
The refrigerant depends on the equipment model and its manufacturing specifications.
Many newer residential systems use lower global-warming-potential refrigerants such as R-454B or R-32, while many older systems use R-410A or R-22.
Refrigerants are not freely interchangeable. Equipment, components, and servicing requirements must be compatible with the specified refrigerant.
We'll confirm the appropriate refrigerant and equipment during your estimate.
Which HVAC brands does Maximum Comfort install?
Maximum Comfort installs equipment from manufacturers such as York, AC Pro, Lennox, Bryant, Bosch, Daikin, Mitsubishi Electric, and Fujitsu, depending on the system and project.
The best option depends on your home's requirements, equipment availability, system design, budget, and warranty terms.
Proper installation and long-term service support matter just as much as the name on the equipment.
Does Maximum Comfort offer financing and free installation estimates?
Yes. We provide free installation estimates for qualifying residential AC, furnace, heat pump, mini-split, and complete HVAC replacement projects.
Financing options may also be available to eligible customers, subject to approval and current lender terms.

Does Maximum Comfort handle commercial HVAC projects?
Yes. In addition to residential work, Maximum Comfort has experience with commercial HVAC installations.
Our work has included large-capacity packaged HVAC equipment for commercial and institutional buildings in San Diego County, including a project in Pine Valley.
Commercial project requirements depend on the building, equipment capacity, access, installation scope, and applicable codes and permits.
