Serving Williamson County

Trusted HVAC Service for Nolensville’s Growing Community

Nolensville has grown fast—new subdivisions tucked into the rolling hills, larger and newer homes filling out the landscape just south of Brentwood, all anchored by a walkable Main Street and the historic Nolensville Feed Mill. Those bigger floor plans and multi-zone layouts put real demand on heating and cooling equipment, and Middle Tennessee’s hot, humid summers and occasional winter cold snaps don’t make it any easier.

Reliable Comfort Services brings 50+ years of combined team experience keeping homes comfortable across the region, and we bring that same standard to Nolensville. Our technicians service all major brands, perform a clear System Performance Evaluation and Safety Inspection on every visit, and explain what they find in plain language. Whether you need an air conditioner back online before the next humid stretch, a furnace ready for a cold front, or a new system sized correctly for a newer home, we’re here to help.

Why Choose Us

Why Nolensville Homeowners Choose Reliable Comfort Services

A Williamson County Resource You Can Count On

Nolensville sits in Williamson County, at the western edge of our service area—roughly 30 to 40 minutes from our Murfreesboro base. Our crews train in-house to one consistent standard, so the values that built our reputation travel well: honest assessments, fair pricing, and standing behind the work.

Right-Sized Systems for Larger, Newer Homes

Williamson County’s growth has filled Nolensville with bigger floor plans, vaulted ceilings, and multi-zone layouts that a one-size-fits-all approach simply can’t serve well. We perform load calculations specific to your home so equipment is matched to the space—proper sizing means even comfort and quieter operation across every room.

A Condition Report You Can Actually Read

On service and inspection visits we provide a System Performance Evaluation and Safety Inspection with a straightforward Red / Yellow / Green condition report. Green means good, Yellow means keep an eye on it, and Red flags something that needs attention. You see the same findings we do, so decisions about repair or replacement are yours to make with clear information.

Licensed, Accredited, and Built for Accountability

Reliable Comfort Services holds a Tennessee Mechanical (HVAC) and Refrigeration Contractor License and is bonded and insured. We carry an A- rating with the Better Business Bureau, and we’re recognized as an LG Pro Dealer and a TVA EnergyRight Quality Contractor. Those credentials reflect ongoing training and a commitment to safe, code-compliant work in your home.

Clear Estimates, Real Warranty Options, and Flexible Financing

Every estimate comes in writing before we begin, so you know the scope and cost up front. New installations are backed by a manufacturer parts warranty of up to 10 years when the equipment is registered, a 12-year parts warranty on qualifying LG ductless systems through our LG Pro Dealer status, an optional third-party labor warranty of up to 10 years, and No-Hassle equipment replacement on qualifying, select equipment if a major component such as the compressor or coil fails. Qualifying equipment may also earn a $50 TVA EnergyRight rebate per unit each year.

Financing That Works for Your Household

When a replacement is the right call, we offer financing through Wells Fargo, TVA Financing, and Synchrony so the timing works for your household. No pressure, no gimmicks—just flexible options that make upgrading to a modern, efficient system more affordable than many homeowners expect.

Protection You Can Count On

HVAC Warranties & Long-Term Protection

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.

Warranty Coverage Options

Manufacturer Parts Warranty (Up to 10 Years)

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.

Optional Labor Warranty (Up to 10 Years)

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.

12-Year LG Parts Warranty

Included on LG ductless installations through our LG Pro Dealer status — one of the strongest coverage packages available. Applies to LG ductless equipment only.

No-Hassle Equipment Replacement (Up to 10 Years)

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

HVAC Questions from Nolensville Homeowners

Yes. Nolensville is part of our service area, sitting in Williamson County at the western edge of the territory we cover—roughly 30 to 40 minutes from our Murfreesboro base. Call (615) 410-6575 to confirm scheduling for your specific address, or review our full service area to see where else we work.

We service all major brands. For new installations we install Tempstar as our primary line for both split and package systems, and we install LG and Mitsubishi for ductless mini-splits as an LG Pro Dealer. If your current equipment is from another manufacturer, we can still repair and maintain it—just let us know what you have when you call.

It’s a thorough check of your system that ends in a simple Red / Yellow / Green condition report. Green means the component is in good shape, Yellow means it’s worth monitoring, and Red flags an item that needs attention. You get the same clear picture we do, so any decision about repair or replacement is made with honest, easy-to-read information.

Yes. Williamson County winters are generally mild, but the occasional cold snap can expose a tired furnace at the worst moment. We service ignition systems, blower motors, heat exchangers, and thermostats, and we install new Tempstar furnaces when replacement makes more sense. Call as soon as you lose heat so we can advise on next steps.

Constant running with weak cooling often points to a refrigerant leak, a dirty or iced evaporator coil, a clogged filter, or a thermostat issue—and larger homes can mask the problem until a hot, humid afternoon makes it obvious. Our visit checks refrigerant pressure, inspects coils for blockage or ice, clears filters and condensate lines, and tests the thermostat. We provide a written estimate before any repair work begins.

Yes. Mini-splits are a great fit for bonus rooms, additions, finished basements, and sunrooms found in many of Nolensville’s larger newer homes, and they avoid major ductwork changes. As an LG Pro Dealer we install LG and Mitsubishi ductless systems prized for quiet, efficient operation, and we handle design, installation, and ongoing service.

Yes. We partner with Wells Fargo, TVA Financing, and Synchrony so a replacement doesn’t have to land all at once. New installations are backed by a manufacturer parts warranty of up to 10 years when the equipment is registered, a 12-year parts warranty on qualifying LG ductless systems through our LG Pro Dealer status, an optional third-party labor warranty of up to 10 years, and No-Hassle equipment replacement on qualifying, select equipment if a major component such as the compressor or coil fails. Explore financing or ask about terms when you request an estimate.

Qualifying high-efficiency equipment may earn a $50 TVA EnergyRight rebate per unit each year. As a TVA EnergyRight Quality Contractor, we can tell you which systems qualify and help you take advantage of available savings when you’re planning an installation.

Routine spring and fall tune-ups catch small problems—low refrigerant, dirty coils, worn parts, loose electrical connections—before they turn into a breakdown on a brutal summer day. Regular service helps your system run the way it was designed to and can extend its useful life, and plan members get priority scheduling plus member benefits.

On new installations, your equipment is backed by a manufacturer parts warranty of up to 10 years when the equipment is registered; we also offer a 12-year parts warranty on qualifying LG ductless systems through our LG Pro Dealer status; you can add an optional third-party labor warranty of up to 10 years; and qualifying systems include No-Hassle equipment replacement on select equipment if a major component such as the compressor or coil fails. We also stand behind our workmanship—if something we repaired isn’t right, we’ll come back and make it right.
