Central Air Conditioner Replacement & Installation

Will a new air conditioner lower my bills?

Everybody’s first question, and the answer is YES! Upgrading to a new central AC unit with a higher SEER (Seasonal Energy Efficiency Ratio) rating can greatly reduce your electricity consumption. In addition, there are also a number of rebates available when you upgrade to a more energy efficient central air conditioner—saving you even more money.

How long will it take GAC to replacement my central AC?

Each central air conditioning installation is different, but we can complete most full system (both indoor and outdoor units) replacements in three to four hours. Our comfort consultant can give you an estimate of the time required when we come to your home for an initial quote.

How do I pay for my new central air conditioner?

At GAC, we do not require any payment prior to the completion of the work we have promised. After your installation is complete, we will test the system, ask you to visually inspect each piece of equipment, and explain any instructions to operate your new system. Only after you are comfortable and satisfied, will we ask for payment.

Payments may be made by credit card (we accept VISA, MasterCard, and Discover), check, or cash. We also offer HVAC financing with approved credit through Bryant and Wells Fargo if you would prefer this method of payment.

Central AC Repair & Maintenance

Leaks. Noises. More perspiration than usual. These are just a few signs that something might be awry with your central air conditioning.
