AC Brands We Install
Choosing the right AC brand is one of several decisions you will make during the installation process, but it is not the only decision that matters. The brand you choose determines your equipment warranty terms, available efficiency levels, noise ratings, and the specific features available to you. At Harpeth Air, we install all major residential AC brands and can recommend the best brand for your specific needs, budget, and preferences. We are not locked into a single manufacturer, which means our recommendations are based on what is best for you, not on dealer agreements.
Carrier
Carrier invented modern air conditioning in 1902 and remains one of the most recognized names in HVAC. Their residential product line spans from entry-level Comfort series systems through the mid-range Performance series to the premium Infinity series with variable-speed compressors and Greenspeed intelligence. Carrier systems are known for excellent build quality, comprehensive warranty coverage, and wide parts availability. The Infinity series with Greenspeed technology is one of the most efficient and quietest residential systems available, achieving up to 24+ SEER2 with a variable-speed compressor that modulates to match demand.
The Performance series at 16 to 18 SEER2 offers an excellent balance of efficiency and value, with two-stage cooling and competitive pricing. The Comfort series provides reliable, no-frills cooling at the minimum efficiency level. Carrier offers a 10-year parts warranty on all components when registered within 90 days of installation. Our factory-authorized installation ensures your warranty is fully valid and your system is set up to Carrier specifications.
Trane
Trane has earned a reputation for durability and reliability, with their tagline "It's Hard to Stop a Trane" reflecting the robustness of their equipment. Their residential lineup includes the XR series for value-conscious homeowners, the XL series for mid-range performance, and the XV series for premium efficiency and comfort. Trane's Climatuff compressors and spine fin coil design are engineered for longevity, which is why Trane systems consistently rank among the longest-lasting residential AC equipment. The XV20i with variable-speed technology achieves up to 22 SEER2 and provides exceptional comfort and humidity control.
The XL series at 16 to 18 SEER2 is one of the best values in the mid-range efficiency tier, offering two-stage cooling with solid construction. The XR series provides dependable cooling at an accessible price point. Trane offers a 10-year limited warranty on outdoor units and a limited lifetime warranty on the heat exchanger for their furnace products. Trane equipment is manufactured in the United States, with major facilities across several states. We have extensive experience installing and servicing Trane systems throughout Nashville.
Lennox
Lennox positions itself as a premium brand with an emphasis on innovation, efficiency, and quiet operation. Their product line includes the Merit series for basic installations, the Elite series for enhanced efficiency, and the Dave Lennox Signature Collection for the highest performance. Lennox introduced some of the first variable-capacity residential systems and continues to push efficiency boundaries. The SL28XCV is one of the most efficient residential air conditioners available, with a SEER2 rating approaching 28. While its premium price puts it at the top of the market, it represents the cutting edge of residential cooling technology.
The XC21 in the Signature Collection and the XC16 in the Elite series are more practically priced options that still deliver excellent efficiency and comfort. Lennox systems tend to be among the quietest in their respective categories, with sound levels as low as 59 decibels on premium models. Lennox offers a 10-year limited warranty with registration. One consideration with Lennox is that they use proprietary parts and components more than some other brands, which can affect repair availability and cost outside of the warranty period. Their dealer network is strong in Nashville, and as a Lennox dealer, we maintain adequate parts access for service.
Rheem & Goodman
Rheem and Goodman serve the value segment of the residential HVAC market, offering solid, reliable equipment at competitive prices. They are not budget brands in the sense of being low quality. Rather, they focus on providing dependable heating and cooling without the premium pricing of brands like Carrier, Trane, and Lennox. Rheem offers systems ranging from 14.3 SEER2 to 20+ SEER2, with their Prestige series providing variable-speed performance at prices significantly below equivalent Carrier Infinity or Trane XV systems. The Classic Plus series offers two-stage cooling at competitive pricing.
Rheem is one of the few manufacturers that makes HVAC equipment, water heaters, and other home comfort products, allowing for system integration. Goodman is known for providing reliable cooling at the most affordable price point. Their GSXC series offers up to 19 SEER2 efficiency with two-stage cooling, while the GSXN series provides basic single-stage cooling at the minimum efficiency. Goodman is manufactured by Daikin, one of the world's largest HVAC manufacturers, which provides manufacturing quality and parts availability. Goodman offers one of the best standard warranties in the industry: a 10-year limited parts warranty including the compressor when registered within 60 days.
For homeowners focused on getting reliable air conditioning at the best possible price, Goodman systems deliver excellent value.
How to Choose the Right Brand
The brand decision should be based on your priorities, budget, and how the available features align with your needs. If maximum efficiency and cutting-edge features are your priority, Carrier Infinity, Trane XV, or Lennox Signature systems represent the premium tier, with efficiency ratings above 20 SEER2, variable-speed operation, and the quietest available performance. If best value at mid-range efficiency is your priority, Carrier Performance, Trane XL, and Rheem Prestige systems deliver 16 to 18 SEER2 efficiency with two-stage cooling at competitive prices. These systems provide excellent comfort improvements over basic equipment without the premium price of the top tier.
If budget is the primary concern and you want reliable cooling at the lowest cost, Goodman and entry-level Rheem systems provide dependable performance with good warranty coverage at the most accessible price point. Beyond brand, remember that installation quality matters more than brand selection for system performance and longevity. A mid-range system installed correctly will outperform a premium system installed poorly. At Harpeth Air, every installation meets the same quality standards regardless of the brand you choose. We recommend focusing on the right size, the right efficiency level, and a reputable installer.
The brand is the final detail, not the driving decision. We are happy to recommend a brand based on your specific situation, but we will never steer you toward a particular brand for our benefit rather than yours.
Frequently Asked Questions
What is the best AC brand?
There is no single best brand for everyone. Carrier, Trane, and Lennox are premium brands with the highest efficiency options and the most advanced features. Rheem and Goodman offer excellent value at more accessible price points. The best brand for you depends on your budget, efficiency goals, and feature preferences. Installation quality matters more than brand choice.
Do you service all AC brands?
Yes. Our technicians are trained to diagnose and repair all major HVAC brands regardless of who installed them. We carry common parts for most brands on our service trucks. If a brand-specific part is needed, we can typically obtain it within one business day through our local supply network.
Are premium brands worth the higher price?
Premium brands offer higher efficiency ratings, quieter operation, more advanced features, and often more comprehensive warranty terms. Whether the premium is worth it depends on your budget and priorities. If comfort, efficiency, and quiet operation are important to you, premium brands deliver measurable improvements. If basic reliable cooling at the best price is your goal, mid-range and value brands serve that need well.
Does the brand affect warranty coverage?
Yes. Warranty terms vary by manufacturer. Most major brands offer a 10-year limited parts warranty when the equipment is registered within 60 to 90 days of installation. Some offer extended compressor warranties. The important factor is that the equipment must be installed by a licensed contractor and registered with the manufacturer to activate the full warranty. We handle registration as part of every installation.
Can I choose a different brand than what you recommend?
Absolutely. We provide recommendations based on your needs and budget, but the final brand decision is yours. If you have a preference for a particular brand based on past experience, recommendations, or research, we are happy to install the brand of your choice as long as it is appropriate for your application.
