Air Conditioning Installation
Your guide to a new air conditioning system that cools efficiently and lasts.
A Cooling System Built to Last
Thinking about replacing an aging air conditioner or installing a brand-new cooling system? This is one of the most important comfort investments you’ll make for your home. At Reliable Comfort Services, we handle the entire process — from understanding your home’s cooling needs and selecting the right equipment to professional installation, system startup, and training you on how to get the most from your new unit.
Our team has installed thousands of air conditioning systems across Middle Tennessee, backed by 50+ years of combined experience. Tempstar is our primary, recommended brand for central air conditioning — a reliable equipment platform with strong warranty coverage — and as an LG Pro Dealer we also offer LG, Carrier, and Trane equipment. We partner with Wells Fargo, TVA Financing, and Synchrony so you can upgrade to a modern system without overwhelming your budget. Our certified technicians understand Tennessee’s summer cooling demands and help you choose equipment built to handle them.
Why Choose Us
Our team brings more than 50 years of combined experience installing air conditioning systems throughout Middle Tennessee. We treat every installation as a long-term investment in your home’s comfort and value. When you work with us, you’re choosing a company that will be here for warranty support, maintenance, and service for as long as you own your system.
For central air conditioning, Tempstar is the brand we recommend most: a reliable equipment platform backed by strong warranty coverage, with available extended warranties and No-Hassle replacement coverage on select tiers. We’re also an LG Pro Dealer, which keeps our technicians trained on the latest efficiency technologies, refrigerant standards, and manufacturer installation best practices.
An air conditioning system that’s too small won’t keep up on hot Tennessee days; one that’s oversized cycles too frequently and wastes energy. We perform load calculations on your home, discuss your budget and efficiency goals, and recommend the right-sized equipment — most often Tempstar, our primary line, along with LG, Carrier, and Trane. The right choice keeps you cool and saves money for years.
We hold a Tennessee Mechanical (HVAC) and Refrigeration Contractor License, maintain full bonding and insurance, and are accredited by the Better Business Bureau with an A- rating. Your air conditioning installation is protected by genuine credentials and the professionalism they represent.
As an approved member of the Tennessee Valley Authority’s Energy Right Quality Contractor Network, we’re committed to installing systems that maximize energy efficiency. Our technicians understand SEER ratings, refrigerant codes, and the newest efficiency standards so your new AC keeps operating costs down from day one.
A new air conditioning installation is a significant investment, but financing options shouldn’t force you to wait. We work with Wells Fargo, TVA Financing, and Synchrony to offer flexible terms. Your system is also backed by layered protection: a manufacturer parts warranty of up to 10 years when registered, an optional third-party labor warranty of up to 10 years if you choose to add it, and No-Hassle equipment replacement on qualifying, select equipment if a major component such as the compressor or coil fails.

Our Process
We start by understanding your home’s unique cooling needs. Our technician walks through your home, noting square footage, insulation, window placement, sun exposure, and any hot spots or poorly cooled zones. We perform a detailed load calculation to determine exactly how much cooling capacity your home needs — not too much, not too little. This is the foundation of choosing the right-sized system, and it’s where many installers cut corners. We take the time to get it right.
Our assessment includes understanding the age and condition of your ductwork, checking for air leaks that waste energy, and identifying any zones that don’t cool well with your current system. We also ask about your current energy bills and comfort complaints — these real-world details inform our recommendations.
Once we know your cooling needs, we walk you through available equipment options. We discuss SEER ratings (seasonal energy efficiency), warranty terms, brand reliability, and long-term operating costs. Tempstar is our primary, recommended line for central air conditioning — a reliable platform with strong warranty coverage, available extended warranties, and No-Hassle replacement coverage on select tiers. As an LG Pro Dealer we can also offer current LG models, along with Carrier and Trane, so you have real choices and understand the trade-offs between them.
Choosing the right efficiency level involves balancing upfront cost against energy savings. A higher-SEER system costs more but saves money monthly. We help you understand the payback period so you can make an informed decision. Financing options from Wells Fargo, TVA Financing, and Synchrony make upgrading more affordable than many homeowners expect.
Before installation day, we prepare your home to ensure a smooth and professional process. This may involve disconnecting the old system (if replacing), preparing the outdoor condenser pad, routing new refrigerant lines to code, or upgrading electrical capacity if your home’s service doesn’t support the new unit. We review the installation plan with you in advance so there are no surprises.
If you’re upgrading from an older system to a new high-efficiency model, modern refrigerants may be required, and some ductwork improvements might enhance performance. We identify these opportunities during the prep phase and discuss them with you clearly. Our goal is to avoid installation-day delays and ensure everything is ready when our crews arrive.
On installation day, our certified technicians arrive with everything needed to complete the job. We install the indoor evaporator coil (if not already present in your system), set the outdoor condenser unit on its pad with vibration isolation, connect all refrigerant lines using proper evacuation and charging procedures, wire the thermostat, and test every component to ensure optimal performance. This is detailed, precision work — we don’t rush, and we don’t cut corners.
Our installation team communicates with you throughout the day so you understand what’s happening. When the system is running, we perform a complete startup sequence: cycling through all modes, verifying that the thermostat controls temperature accurately, testing safety shutdowns, and checking airflow from every register. We take pressure and temperature readings to verify the system is operating at design specifications.
Before we leave, we spend time with you so you understand how to operate your new system. We show you how to adjust the thermostat, explain your warranty coverage in detail, discuss filter replacement schedules (usually every 1–3 months depending on your filter choice), and outline the basics of system maintenance. We answer any final questions and leave you with all documentation for future reference.
We also explain the importance of annual maintenance — a spring tune-up before cooling season keeps your system running efficiently, catches minor issues before they become failures, and keeps your warranty valid. Our maintenance plans make staying on schedule easy and offer repair savings if issues do arise.

Protection You Can Count On
We stand behind our work and the equipment we install. Every new residential install can add an optional labor warranty of up to 10 years through a third-party program, and our LG Pro Dealer status includes a 12-year parts warranty on LG ductless systems — among the strongest coverage available. That’s how confident we are in the quality of our work.
Parts and major components are covered up to 10 years when the equipment is registered. We handle registration and keep your documentation. Coverage varies by equipment.
Available as an option on any residential unit we install, through a third-party program. If selected, it covers repair labor for up to 10 years — you choose whether to add it.
Included on LG ductless installations through our LG Pro Dealer status — one of the strongest coverage packages available. Applies to LG ductless equipment only.
Available on qualifying, select equipment only — if a major component such as the compressor or coil fails within the coverage period, the unit is replaced rather than repaired.

Answering Your Questions
Cost varies based on the size of the system, the efficiency level you choose, and any ductwork or electrical work your home needs. We provide a clear written estimate so you know exactly what’s included, and financing options make the investment manageable. The best way to know is to request a free estimate — we’ll break down equipment and labor costs clearly.
A typical central AC installation takes one to two days, depending on whether you’re replacing an existing system or installing in a new home. Most residential installations are completed in a single day, with a possible follow-up visit for final testing. We’ll confirm the timeline during your estimate.
SEER (Seasonal Energy Efficiency Ratio) measures cooling efficiency over a typical cooling season. SEER2 is a newer standard that reflects real-world conditions more accurately. Higher SEER/SEER2 ratings mean lower energy bills, but they also cost more upfront. We help you balance efficiency improvements against your budget.
If your furnace is aging or showing signs of wear, replacing both systems together can be smart — they work as a team, and you get coordinated ductwork, controls, and warranties. But if your furnace is relatively new and functioning well, replacing just the AC is fine. We’ll give you an honest assessment during your estimate.
Tempstar is our primary, recommended brand for central air conditioning — a reliable platform with strong warranty coverage. As an LG Pro Dealer we also install LG equipment, along with Carrier and Trane. Each brand has its strengths, and we help you understand the differences in warranty, efficiency, and long-term reliability so you make the choice that’s right for your home. We also service and repair all major brands, including Goodman and Ruud.
Usually yes. If you’re replacing an existing AC unit and your ducts are in good condition, sealing, and insulated, we can reuse them with a new system. Sometimes ducts need minor modifications or sealing to work optimally with new equipment. We assess this during your estimate and let you know if upgrades would improve efficiency.
We remove and dispose of your old system responsibly. The refrigerant is safely captured and recycled, and metal and other materials are recycled when possible. There’s no additional cost — it’s included in the removal process.
Yes. Once you have a new air conditioning system, we strongly recommend annual maintenance to keep it running efficiently and under warranty. Our maintenance plans include spring and fall tune-ups, priority service calls, and savings on repairs. You can sign up when we install your system or anytime after.
A new system can be backed by three layers of coverage. First, a manufacturer parts warranty of up to 10 years when the equipment is registered — we handle registration and keep your documentation, since coverage varies by equipment and many warranties require it. Second, an optional third-party labor warranty of up to 10 years, covering repair (labor) costs for up to a decade. Third, No-Hassle equipment replacement on qualifying, select equipment, which replaces the unit rather than repairing it if a major component such as the compressor or coil fails within the coverage period. We also offer service agreements that extend coverage beyond the manufacturer’s terms.
Yes, as an option. On any residential system we install, you can choose to add a third-party labor warranty of up to 10 years. It isn’t automatically included, but if you add it, it covers repair (labor) costs for up to a decade — on top of the manufacturer parts warranty (up to 10 years when registered) and No-Hassle equipment replacement on qualifying, select equipment if a major component fails. We’ll explain every option and any cost during your estimate.
With proper maintenance, modern air conditioning systems typically run reliably for 12–18 years. High-efficiency units sometimes last even longer. The key to longevity is annual tune-ups, filter changes, and prompt repair of any issues. Our maintenance plans help you get the most years of reliable operation from your investment.
Your current thermostat may work with a new air conditioning system, but newer programmable and smart thermostats offer better comfort control and can reduce energy bills. Many homeowners choose to upgrade to a smart thermostat during installation for features like remote control, learning schedules, and energy reporting. We can discuss options during your estimate.
That’s determined by your home’s cooling load — a calculation based on square footage, insulation, windows, sun exposure, and climate. Oversizing wastes energy and cycles too often; undersizing can’t keep up on hot days. This is why our load calculation is so important. There’s no simple “one ton per square foot” rule that works for every home.
Replacement installations typically reuse existing ductwork and electrical connections, which makes them faster and less costly. New construction installations may require running all new ducts, refrigerant lines, and electrical from scratch. We assess your specific situation during the estimate and explain what’s involved.
