AC Installation in Sacramento, Done in a Day
When Sacramento summers hit, an undersized or failing system stops being an inconvenience and becomes a real problem. Alpha Mechanical has been installing and replacing residential AC across Sacramento since 2011. Every technician on our team is licensed, certified, and trained on the equipment manufacturers produce today. Beyond installation, we offer AC replacement Sacramento homeowners can count on — from load calculations to the final city inspection.
Do You Need AC Installation or AC Replacement?
Before committing to either path, take a look at our HVAC replacement guidelines to figure out which option fits your situation.
New AC Installation
Some homes have never had central air; others outgrew their original setup after a remodel. New installation makes sense when there is no existing equipment to work from, or when the current layout is so mismatched to the home's size that starting fresh is the only practical path. Getting the unit sized correctly from the start matters more than most homeowners expect — too large and it short-cycles, too small and it never catches up on a triple-digit afternoon.
AC Replacement
If your system is 15 years old and repair estimates are climbing, AC replacement is worth running the numbers on. Sacramento's heat puts more strain on equipment than the national average, which tends to shorten local system lifespans. A new high-efficiency air conditioning unit in a roughly 2,000-square-foot home can cut electric bills by around 60% annually compared to a 20-year-old system.

Our AC Installation Process
Step 1 — Free Estimate and System Design
We assess your home, run load calculations, and recommend the right equipment — at no charge.
Step 2 — Permits and Title-24 Testing
We pull the city building permit and complete Title-24 testing: airflow, duct leakage, refrigerant charge, and equipment verification.
Step 3 — Removal of the Existing System
The old unit is removed and disposed of, and refrigerant is recovered in compliance with EPA requirements.
Step 4 — System Installation
We install the new system, including crane service for package units, rooftop adapter curbs where needed, and a secondary drain pan for attic split systems.
Step 5 — Ductwork Modifications
Supply and return plenums are modified, and existing ductwork is reconnected to the new equipment.
Step 6 — Electrical and Gas Work
We install properly sized circuit breakers and new high-voltage disconnects and wiring for the outdoor condenser. If your system pairs the new AC with an existing furnace and the gas connection needs attention, we address it in the same visit.
Step 7 — Refrigerant and Controls
Precision refrigerant charge is set, a new refrigerant line-set is installed for variable-speed systems, and your choice of Wi-Fi or programmable thermostat is fitted.
Step 8 — Safety Devices
Smoke detectors and CO sensors are installed if not already present. Every install meets current California code requirements.
Step 9 — Commissioning and Cleanup
The system is started up, tested, and walked through with you. We leave the site clean.
What to Consider When Installing a New AC
- System sizing — a proper load calculation determines the right unit. Oversized equipment short-cycles and underperforms on humidity; undersized equipment never catches up.
- Efficiency and energy costs — higher SEER ratings mean lower monthly bills. Variable-speed systems and smart thermostats add upfront cost but pay back in a climate where cooling runs hard for months.
- Budget and rebates — federal tax credits and utility rebates can meaningfully reduce out-of-pocket cost. Check eligibility before choosing a system.
- Licensed installation and code compliance — the contractor you choose determines whether permits get pulled, refrigerant is handled to EPA standards, and Title-24 requirements are met.
Signs You Need AC Replacement
- Your HVAC system is 15 years old or older
- Cooling performance has dropped noticeably even with clean filters
- Repair bills are adding up faster than a new system would cost
- Energy bills are climbing without a clear reason
- The system uses R-22 refrigerant, which is no longer manufactured
- Frequent breakdowns make replacement the more practical option
