Best Rated HVAC Systems for 2019

These are the best complete heating and air conditioning systems for 2019.

  • Trane XR HVAC Series
  • Day & Night Constant Comfort HVAC Series
  • Rheem Classic HVAC Series
  • Bryant Preferred HVAC Series
  • Goodman GSX/GSZ and GMSS HVAC Series
  • American Standard Platinum HVAC Series
  • Heil QuietComfort Deluxe Series
  • Lennox Signature Series
  • Carrier Infinity Series
  • Daikin VC/MC HVAC Series



HVAC components are designed to work together to give you your preferred performance level. Common examples are:

  • A single-stage AC paired with a single-stage furnace with a multi-speed blower
  • A two-stage heat pump combined with an air handler with variable-speed blower

The first pair would give you basic but affordable heating and cooling.

The second pair would deliver better efficiency and indoor climate control, but at a higher cost.

This guide to the best HVAC systems for 2019 is divided into basic systems and premium systems, like the example above.

The Best 2019 HVAC Systems: Standard Performance

Most components in these systems deliver one stage of heating and/or air conditioning. A few are two-stage.

Pros: The upside is lower equipment costs and lower repair costs because the compressors, blowers and other essential parts are simpler.

Cons: The disadvantage is that these systems might create slightly noticeable temperature fluctuations. In summer, they don’t remove as much humidity. Since they run at full capacity when on, they are louder than two-stage and variable-capacity systems running at lower capacities.

Efficiency: All HVAC systems are becoming more efficient, so the gap in efficiency between premium and basic systems is getting smaller. You can get a single-stage system that will still keep your operating costs under control in very warm and very cold climates.

Many HVAC installers recommend single-stage equipment to their customers for the reasons described.

Important: These are not the cheapest systems made by these brands. The cheapest systems don’t belong on a “Best” list.

  • SEER: Cooling rating for ACs and heat pumps

How to Choose the Best HVAC Series for Your Home

All the brands in this list will deliver excellent performance and durability – but only when properly installed.

Installation issues more than brand quality account for early mechanical failure and the system not running as efficiently as it should.

To find the best fit for your home, find an experienced installer.

  1. Request estimates from 3+ proven HVAC companies in your area
  2. Ask about their history, and don’t choose a newer company with little experience
  3. Ask about the experience of the crew that will install your HVAC system
  4. Check online reviews at Google, Yelp and the BBB
  5. Select an installer you believe will do the best job sizing the system and installing it according to manufacturer guidelines

That process can take several weeks. If you’d like to move more quickly, consider using our partner service that provides you with Free Written Estimates from top installers in your area.

There is no cost or obligation, and the companies are prescreened for expertise, experience and customer service.
