How long does an AC installation take?

Most residential AC installations are completed in one day, often within four to eight hours. Jobs that include new ductwork, a new indoor coil in a hard-to-reach attic, or electrical upgrades can take longer. Your technician will give you a time estimate along with the by-the-job price before the work is schedule

What size air conditioner does my home need?

The right AC size depends on your home's heat gain, which is shaped by square footage, insulation, window type, ceiling height, and sun exposure. Square footage alone is not enough to size a system correctly. During your free estimate, Aire Serv Alamo Heights can perform a heat gain and heat loss evaluation to recommend a system that cools evenly and controls humidity.

How do I know if I need a new air conditioner?

You likely need a new air conditioner if your system is more than 12 to 15 years old, needs repairs every season, uses R-22 refrigerant, or can no longer keep your home comfortable on hot afternoons. Rising energy bills and uneven temperatures between rooms are also common signs. A free in-home estimate will show whether repair or replacement is the better investment.

How much does a new AC unit cost?

The cost of a new AC unit depends on system size, efficiency rating, and installation needs such as ductwork or electrical changes, so we do not quote a price without seeing the home. After a free in-home evaluation, you receive one upfront price for the complete installation. Financing is available, and qualifying customers can apply a 10% discount when it is the best available offer.

A Smarter Way to Replace Your Air Conditioner

Free estimates, firm pricing, and coverage for Alamo Heights homeowners.

A new air conditioner is a major purchase, so your estimate is free. During the visit, we can perform a heat gain and heat loss evaluation on your Alamo Heights home to confirm the system size it needs and whether your current unit was sized correctly. If another company has already recommended a replacement, ask about our Free Second Opinion promotion. We prefer to see your system in person, but we can also give a projected estimate over the phone based on what you describe.
Your AC install quote covers the job as a whole rather than an hourly rate, so the price you approve is the price you pay. Installations are scheduled between 8 a.m. and 7 p.m., Monday through Saturday, with an extra charge for Saturday appointments. If your current system can be repaired for a reasonable cost, we will tell you, and there is no diagnostic fee when you have that repair completed. Need someone out quickly? Ask about same-day service, offered whenever an opening exists.
Financing is available, so a failed AC does not force you to pick a system based only on cash on hand. Seniors, veterans, active military, first responders, and teachers save 10%, and when another special is running, we apply the one that saves you more. Manufacturer warranties apply to qualifying equipment and parts, warranty packages extend your coverage, and workmanship issues are corrected at no charge under the Neighborly Done Right Promise®.

What to Expect During Your AC Installation

A professional AC installation starts with a load evaluation of your Alamo Heights home, looking at square footage, insulation, windows, and sun exposure to choose the right capacity. Oversized units short cycle and leave humidity behind, while undersized units run constantly and still fall short on hot afternoons. On installation day, the crew protects your floors, recovers refrigerant from the old system, and removes the outdated equipment. They then set the new condenser and matching indoor coil, connect refrigerant lines, wiring, and the condensate drain, and pull a vacuum before releasing refrigerant. The technician starts the system, verifies refrigerant charge, airflow, and temperature split, checks thermostat operation, and walks you through filter changes and basic care before leaving.
