About HVAC Compared

Last updated: August 2026

Who We Are

HVAC Compared is an independent review site dedicated to helping homeowners make informed decisions about HVAC systems, equipment, and services. We evaluate heating, cooling, and ventilation solutions with hands-on testing and provide transparent recommendations based on performance, efficiency, reliability, and real-world cost.

Our mission is to demystify HVAC technology and help you find the right system for your climate, home size, and budget — without bias toward manufacturer relationships or affiliate incentives.

Our Testing Methodology

Every HVAC system and component reviewed on HVAC Compared follows a rigorous evaluation framework:

• Seasonal performance testing: We test systems across heating, cooling, and shoulder seasons to evaluate real-world seasonal efficiency and performance variations.
• Energy efficiency measurement: We measure SEER, HSPF, and actual power consumption under various operating conditions and compare published specs to real-world performance.
• Noise and vibration testing: We measure decibel levels at common distances and evaluate compressor, fan, and ductwork noise during operation.
• Installation evaluation: We assess ease of installation, compatibility with existing ductwork, and typical installation time and cost across different home configurations.
• Thermostat and controls: We test smart thermostats, app reliability, temperature accuracy, scheduling reliability, and integration with home automation systems.
• Maintenance requirements: We document filter access, refrigerant recharge procedures, seasonal maintenance needs, and parts availability.
• Warranty coverage: We compare actual warranty terms, coverage limits, and manufacturer support reputation based on user reviews and repair service data.

Editorial Independence

Our reviews are not influenced by affiliate relationships. We maintain independence by:

• Independent testing first: We select systems based on market demand and reader interest, not affiliate commission structures.
• Honest performance scoring: HVAC systems are ranked by actual efficiency, reliability, and value — never by payout amounts.
• No pay-for-placement: Manufacturers cannot pay for higher rankings or featured placement in our comparisons.
• Public testing criteria: Our evaluation process and weighting criteria are fully documented so readers understand our conclusions.
• Affiliate disclosure: We clearly identify affiliate links and explain our business model. See our full disclosure.

How We Make Money

This site is supported by affiliate commissions from HVAC equipment manufacturers, installers, and service providers. When you purchase through our links, we earn a commission at no extra cost to you. This model keeps our reviews free and accessible. However, affiliate relationships never influence which systems we choose to test or how we rank them.
