Which brand of A/C is best? Check out our guide to the best HVAC brands!

It’s tough to say exactly which brand of air conditioner is best because there are several excellent brands and models on the market today, but fear not! Based on 2020 and 2021 reviews and consumer reports, we’ve assembled a helpful, at-a-glance guide to the best HVAC systems currently available for purchase. When you shop for a central air and heating unit, you’re making an investment that should last many years and contribute significantly to the value and comfort of your home. It’s important to consider various factors related to the purchase and weigh them according to their importance to you.

These factors include price, size, lifespan, warranty, efficiency, reliability and value because a cheaper unit may require more repairs over time. While our list is anything but comprehensive and shouldn’t be viewed as a ranking — we present the options in no particular order — we believe each of the brands profiled below offers a solid product (or series of products) worth your time and money. First, let’s go over a few of the factors for consideration before a purchase, then profile the best HVAC brands on the market as we see it. We’ll wrap up with a few more of those factors and our overall conclusions and recommendations for further reading on this complex subject, which can sometimes feel overwhelming. Happy reading, good luck on your search, and stay cool!

Size and efficiency

HVAC units are built and classified according to the size of the space they will heat or cool, not the size of the unit itself. It’s important to purchase the right-size unit for the home it will  service. To measure efficiency, we predict the cost of operation, with higher ratings indicating a more efficient system with lower associated energy costs. These efficiency standards include:

  • SEER: Measures efficiency as seasonal temperatures shift, with a rating from 13 to 26.
  • EER: Measures electricity required to run at 95 degrees F outside while maintaining 80 degrees F inside.
  • Energy Star: U.S. government-backed program that certifies appliances as efficient.
  • HSPF: Measures heat output and energy consumption over regular heating seasons.

Of these efficiency standards, the one most widely used is the SEER measurement, so we’ll generally refer only to this measurement for our purposes.

Price and warranty

The cost of a new HVAC unit, including brand-certified but negotiable installation, typically costs between $3,500 and $7,500. Warranties vary but can save you considerable money over the system’s lifetime. The best warranties cover at least 10 years of service and parts, and sometimes they even transfer to a new homeowner, a helpful selling point if you move.

Life spans and features

A new HVAC unit should last between 12 and 15 years, though they can last significantly longer. Annual maintenance by a professional, combined with regular filter changes you can easily do yourself, can help extend an HVAC unit’s life span. Fancy features for additional comfort and convenience include built-in HEPA filters, quieting insulation, dehumidifiers, and separate cooling and heating zones with an included smart or programmable thermostat.

Reliability and value

As you can see, when it comes to making an important decision like what brand of HVAC system to purchase and install for your home, there are plenty of factors to consider, alongside many viable options and several good brands. Determining which brand of air conditioner is best is never as simple as it sounds. Choosing any of the brands we’ve profiled above should put you in an excellent position to have quality home heating and cooling for years to come.

Again, you’ll want to keep your eye on the long-term investment when you make your decision because an HVAC unit should last at least a decade. This realization puts reliability and value into sharper focus. If you constantly spend money on repairs and maintenance, soon that lower upfront sticker price (and maybe the cheaper installation by technicians who were not necessarily certified to install your particular brand) won’t seem like much of a discount. As with most purchases, there’s truth to that old saying about getting what you pay for. If you can afford it, sometimes spending more upfront makes better sense in the long term.
