Air Conditioning Installation & Replacement

Any Problem. Anytime. Anywhere.

Professional Air Conditioning Installation & Replacement Services

How Our Air Conditioning Installation Service Works

Our air conditioning installation service determines how your system will perform for years to come. Every AC unit installation follows a process built around your home’s actual cooling demand:

Load calculation based on square footage, insulation levels, window exposure, and airflow requirements to match system size to your home

Unit positioning for proper airflow and accessibility, covering both indoor and outdoor components

Refrigerant line installation with correct routing and insulation, alongside electrical connections configured for system operation

Refrigerant charging to manufacturer specifications, with airflow balanced across vents for even cooling throughout your home
Full system test under load monitoring temperature, pressure, and cycling behavior to confirm stable performance before completion

How We Handle Air Conditioning Replacement

Our air conditioning replacement starts with understanding how your current system is performing.

System performance evaluation covering age, repair history, and run frequency to confirm replacement is the right long-term call

Efficiency assessment measuring temperature delivery and energy usage patterns to identify what the current system is losing

Replacement system selection matched to your current needs — not outdated assumptions from the original install

Pre-installation review of ductwork airflow, electrical capacity, drainage, and thermostat compatibility to ensure proper operation from day one
Full cooling cycle verification after installation to confirm system stability and performance

We Service Every Type of Cooling System

Different homes require different cooling solutions. TJ’s Plumbing & Heating, Inc. installs and services each system type based on measured demand and tests under real operating conditions.

If your current system is showing performance issues before replacement becomes necessary, our AC tune-up and air conditioning repair services keep it running through the season.

Central Air Conditioning Systems

Central AC delivers consistent cooling across every room when sized, balanced, and connected to properly evaluated ductwork. Every installation accounts for all three.

Where air quality is a priority alongside cooling, air purifier installation is available as part of the same service scope.

Heat Pump Systems

Heat pumps handle both heating and cooling from a single unit. Proper configuration at installation determines how efficiently and reliably the system performs through every season.

For homes using a heat pump as the primary heating source, our furnace installation service covers supplemental heat options for climates where the heat pump alone undersupplies on the coldest days.

Ductless Mini-Split Systems

Homes without ductwork — or rooms that need targeted temperature control — benefit from ductless systems that deliver zone-based comfort without the efficiency losses of traditional ducted setups.

Frequently Asked Questions

How do I know if I need air conditioning replacement instead of repair?

A system over 10 years old, one that has required multiple repairs in a single season, or a unit running on R-22 refrigerant — now phased out and increasingly expensive to source — are the clearest replacement candidates. When the next repair estimate exceeds half the cost of a new unit, replacement delivers better value over the following decade.

How is a new AC system sized for my home?

Sizing runs through a Manual J load calculation — a standardized method that accounts for square footage, ceiling height, insulation levels, window area, and local climate data. An oversized unit short-cycles before dehumidifying properly; an undersized one runs continuously without reaching the setpoint. Accurate sizing is what prevents both outcomes.

How long does AC installation take?

A standard central AC replacement wraps up within a day. New system installations involving refrigerant line rerouting, electrical panel upgrades, or ductwork modifications run longer, with a confirmed timeline established once the scope is assessed.

Will a new AC system lower my energy bills?

Yes. Modern high-efficiency units carry SEER2 ratings significantly above the minimum standard, translating directly to lower operating costs per cooling hour. A system replacing a 10-plus-year-old unit typically delivers 20 to 40 percent reductions in cooling-related energy use, depending on the efficiency gap between the two units.

What should I expect after installation is complete?

A post-installation startup includes verifying refrigerant charge, testing airflow at each register, confirming thermostat communication, and running the system through a full cooling cycle. The system must be performing to spec before the job is closed out.
