Why Choose Us
Our team brings more than 50 years of combined experience in HVAC throughout Middle Tennessee. We’ve earned our reputation by showing up, doing the job right, and standing behind every service call with integrity and accountability.
We maintain active dealer status with LG, one of the world’s leading air conditioning manufacturers. This partnership gives us direct access to the latest training, parts, and equipment — ensuring you get cutting-edge cooling technology backed by manufacturer support.
While we specialize in LG systems, we repair and service air conditioning units from Carrier, Trane, Ruud, Goodman, Tempstar, and Mitsubishi Electric. No matter what brand cools your home, our technicians have the expertise to diagnose and fix it.
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. These credentials aren’t decorative — they represent our commitment to doing business the right way and protecting your investment.
As an approved member of the Tennessee Valley Authority’s Energy Right Quality Contractor Network, we meet rigorous efficiency and service standards. This means you’re getting advice grounded in real energy science, not just sales pitches.
When your air conditioner fails during a Tennessee heat wave, waiting isn’t an option. We offer same-day emergency service for AC breakdowns when scheduling allows, helping your family stay comfortable even when temperatures climb into the 90s. Our trucks carry common parts, so many repairs are completed the same day we diagnose them.
Complete Air Conditioning Services
Our air conditioning offerings are designed to meet every cooling need — from emergency breakdowns to long-term comfort planning.
Our comprehensive services include:
Our Services
Your air conditioner isn’t cooling, running constantly, or making unusual noises. We diagnose the problem, explain what’s happening, and get your system running efficiently again. Same-day service available for emergencies.
Our certified technicians carry common parts and diagnostic equipment to complete most repairs on the first visit. We explain the problem clearly and provide upfront pricing before starting any work.
Thinking about a new air conditioning system? We handle equipment selection, sizing, installation, and startup. We work with financing options to fit your budget.
Our LG Pro Dealer status gives us access to the latest high-efficiency equipment, and we also install systems from Carrier, Trane, Ruud, and Goodman. We perform proper load calculations to ensure your new system is sized correctly for your home.
Preventative maintenance catches problems before they become failures. Our annual tune-ups clean coils, check refrigerant levels, test electrical components, and ensure your AC runs at peak efficiency when you need it most.
Regular maintenance extends system life, prevents unexpected breakdowns, and keeps your warranty valid. Our maintenance plans make it easy to stay on schedule with automatic reminders and priority service.
Heat pumps provide both cooling and heating in one system. If yours needs service or you’re ready to upgrade, we offer the same expertise and financing options as our stand-alone air conditioning service.
Heat pumps are especially efficient in Tennessee’s moderate climate, providing year-round comfort with lower operating costs than separate heating and cooling systems.
Beyond central air conditioning, we install and service ductless mini-split systems, package units, and indoor air quality solutions. We also provide commercial HVAC services for rooftop units and VRF systems.
Whether you need zone cooling for specific areas, whole-home air filtration, or commercial HVAC service, our certified technicians have the expertise to keep you comfortable.

Regular maintenance is the key to reliable cooling and lower energy bills. Our maintenance plans include annual tune-ups, priority service, and repair discounts to keep your AC running smoothly year after year.

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
First, check your thermostat and make sure it’s set to cooling mode and the temperature setting is below the actual room temperature. Check the circuit breaker to ensure the AC hasn’t tripped a breaker. If those basic checks don’t help, call us right away. We offer same-day emergency service for AC failures. Don’t run a broken system — it can damage the compressor and create a much bigger repair bill.
We recommend a professional tune-up at least once a year, ideally before the cooling season starts in spring. Regular maintenance helps prevent unexpected breakdowns, keeps your system efficient, and helps keep your warranty valid. Our maintenance plans make it easy to stay on schedule.
Our tune-up includes coil cleaning, refrigerant level check, capacitor testing, electrical component inspection, filter replacement, and a complete system performance test. We check everything that affects cooling efficiency and reliability.
Most AC units run reliably for 12–18 years with proper maintenance. After 15 years, efficiency drops noticeably and repair costs climb. If your system is aging, we’ll help you understand whether repair or replacement makes economic sense.
Yes. While we’re LG Pro Dealers, we service and repair AC systems from Carrier, Trane, Ruud, Goodman, Tempstar, and Mitsubishi Electric. Bring us any brand and we’ll diagnose and fix it.
Refrigerant is the chemical that absorbs heat inside your home and releases it outside, making cooling possible. If your AC is low on refrigerant, it’s a sign of a leak. Leaks reduce cooling performance and waste energy. We find leaks, repair them, and refill refrigerant to proper levels.
Repair costs vary by the specific problem — a capacitor or contactor replacement is typically straightforward, while a compressor or coil repair involves more labor and parts. The best way to know is to call for a diagnosis. We’ll explain the problem and repair costs upfront before we start work, so you can decide if repair or replacement makes sense for your situation.
We serve Murfreesboro, Smyrna, La Vergne, Christiana, Nolensville, and Mount Juliet. If you’re in one of these communities, call us at (615) 410-6575 to schedule service.
Yes. We work with Wells Fargo, TVA Financing, and Synchrony to offer flexible options. We can discuss financing before you make a decision, so price doesn’t get in the way of comfort and efficiency.
If your system is under 10 years old and the repair costs less than 50% of a new unit, repair usually makes sense. If it’s older than 15 years, has a history of repairs, or the fix costs more than 50% of replacement, we’ll recommend a new system. We always give you the full picture so you can decide.
Yes, we offer same-day emergency service for AC breakdowns. When your air conditioner fails during a Tennessee heat wave, waiting isn’t an option. Our trucks carry common parts, so many repairs are completed the same day we diagnose them.
We’re LG Pro Dealers and specialize in LG equipment, but we also install systems from Carrier, Trane, Ruud, Goodman, and Tempstar. Each brand has different strengths in efficiency, warranty, and reliability. We help you choose the right option for your home and budget.
Regular maintenance is the most important factor. Beyond that, changing filters regularly, sealing air leaks, adding insulation, and upgrading to a programmable or smart thermostat all help. We can assess your home and recommend specific improvements during a service call.
