CSI Mechanical Home / Services / Installation


Is it time to say goodbye to that cranky, old air conditioner or heat pump? You should be cool and comfortable at home. If your air conditioning system costs too much to run and too much to repair, you might need a replacement in the near future. CSI Mechanical is here to help you select a new Trane HVAC system. Our experienced service technicians and installers will make sure that your new air conditioner functions optimally. Here’s what you can expect during the AC installation process.


If you’d like an estimate for air conditioning installation, the owner of CSI Mechanical will visit your home to discuss the project with you and give you a detailed written quote. We offer friendly service and no-pressure, no-obligation estimates. We don’t push the HVAC equipment that makes us the most money. We recommend the products and services that are best for you.

One goal of the consultation is to determine what you want to achieve and which features are most important to you. We’ll go over efficiency ratings, new technologies and prices to get your input. During the consultation, we’ll also assess your home’s cooling requirements, existing equipment and ductwork to give you an accurate opinion and to determine the size of your new air conditioning system.


After 15 or 20 years of use, air conditioners and heat pumps generally require replacement. A new cooling system is a big purchase, but it’s a small price to pay for years of comfort and reliability. Our professional staff members can install a new system that fits your budget and keeps your family perfectly cool during the humid summer weather in Shelby, Patterson Springs, Light Oak, Cherryville, Fallston, Forest City, Gastonia, King’s Mountain, Lawndale, Lincolnton, Polkville, Spindale, NC and the surrounding area. All AC installation jobs are performed by experienced technicians. You’ll receive quality workmanship that will help your new HVAC unit last longer and run more efficiently.


We are happy to offer our customers industry-leading HVAC products manufactured by Trane. All of the equipment that we install — including compressors, air handlers and thermostats — is covered under the brand’s limited warranty. Plus, our air conditioning installation services are covered by a 100-percent satisfaction guarantee. Our installation technicians follow all best practices and manufacturer recommendations to help you to enjoy a better return on investment and lower cost of ownership.


We have more than 60 years of experience serving homeowners and businesses in the area. If you need to replace your old air conditioner, there’s no time like the present.
