A new air conditioner needs to be sized for your home and installed correctly the first time, or it will run inefficiently and fail early. Infinity Heating and Air Conditioning installs central air conditioners, ductless mini-splits, and heat pump systems for homeowners throughout Collierville, matching equipment capacity to the home instead of guessing at a size. Replacing a system that has reached the end of its service life and adding cooling to a space that never had it are both common reasons Collierville homeowners call us, and the installation process starts the same way in either case: an honest, on-site assessment of what your home actually needs.
We at Infinity Heating and Air Conditioning are licensed in the State of Tennessee and have served Collierville and the surrounding Shelby County communities for more than a decade. Every installation is performed by trained technicians, backed by a written estimate before any work begins.
A repair is not always the right call. Homeowners in Collierville typically need a new installation, rather than another repair, when:
If more than one of these applies, installation is usually the more cost-effective path over the life of the system than continuing to repair an aging or mismatched unit.

Every installation starts with an in-home visit, not a phone quote. We measure the home, inspect existing ductwork or evaluate the space for a ductless system, and calculate the cooling load the house actually needs using a Manual J-style load calculation rather than sizing off the old unit’s tonnage.
From there, we walk through equipment options and present a written estimate before any work begins, so you know the full scope of the job before committing to it. On installation day, our technicians set the outdoor condenser, indoor coil, or air handler, and connect refrigerant lines and electrical work to manufacturer specifications. We protect flooring and work areas while the job is underway, and we clean up thoroughly once the equipment is in place. We test the system under load, check refrigerant charge, and walk the homeowner through the new thermostat and any warranty registration before we leave. If your home’s existing ductwork needs modification to support the new equipment, we handle that as part of the same visit rather than sending a separate crew on a separate day.

The single biggest mistake in AC installation is sizing equipment off guesswork instead of the climate the system actually has to handle. According to the National Weather Service Memphis forecast office, the Memphis area’s normal high temperature in July is 91.9 degrees, with summer nights staying warm as well. A system sized for a milder climate, or one sized by “what was there before,” will run constantly during a Collierville summer and still struggle to keep the home comfortable.
A correctly sized system uses a load calculation that accounts for square footage, insulation, window orientation, and the local design temperature, not a flat number of tons per square foot. Oversizing causes a system to cool the air quickly without running long enough to remove humidity, leaving the home feeling clammy even at the right temperature. Undersizing means the system runs nonstop during the hottest weeks of the year, driving up energy bills and shortening the compressor’s life. We size every Collierville installation to this area’s actual summer heat load, not a rule of thumb.
Every installation is priced after the in-home visit, but the variables that typically move the estimate include:
We provide a written, itemized estimate before any work begins so there are no surprises once installation starts, and we explain what drives the number rather than handing over a flat price with no breakdown.
Installation is usually the better long-term choice when the system is old, repairs keep recurring, a room in the house has no cooling coverage at all, or you are moving into new construction with no system in place. A single repair on an otherwise sound unit is often still the right call, so the decision depends on the specific system’s age and repair history. A technician can confirm which situation applies to your home during an in-home visit rather than guessing over the phone.
The right size comes from a load calculation that factors in square footage, insulation, window orientation, and Collierville’s summer heat, not a flat rule based on home size alone. Oversized equipment cools quickly but does not run long enough to remove humidity properly, while undersized equipment runs constantly and still falls short on the hottest days. We calculate the load on-site before recommending any specific equipment, so the size matches your actual home rather than a generic estimate.
Most single-system residential installations in Collierville are completed in one day, including setting the outdoor condenser, connecting the indoor coil or air handler, and testing the system under load before we leave. Jobs that also require significant ductwork modification or electrical upgrades can take longer, and we will tell you that upfront in the written estimate. We always test the completed system before considering the job finished.
Yes. We install central systems and ductless mini-splits for additions, converted garages, and new construction that need cooling coverage added or installed for the first time. A ductless mini-split is often the simpler option for a space with no existing ductwork, since it avoids cutting new duct runs through finished walls or ceilings. We evaluate the space during the in-home visit and recommend whichever option fits the room and your budget.
We are a Trane Authorized Dealer and install Trane air conditioners, heat pumps, and furnaces to Trane’s qualification standard. We also install other manufacturers’ equipment depending on the home’s needs, the space available, and the homeowner’s budget. Whatever system you choose, it is backed by our installation workmanship and the manufacturer’s equipment warranty.
Yes, financing is available for qualifying installations, in addition to free in-home estimates on every job. Financing terms depend on the lender and the homeowner’s application, so specific rates are not something we can quote in general content like this. Ask about current financing options when you schedule your in-home estimate, and we will walk you through what is available at that time.
