So does it? The quick answer is “typically not.” At the 14-16 SEER single stage compressor range, most systems are virtually identical. Upwards of 75% of components from brand to brand are manufactured by a third party company, including the compressor, fan blower and other electronic components. The only components unique to a brand are often the evaporator coil, condenser coil and jacket (outside casing).
At the higher end of the efficiency range (i.e.- 20+ SEER), brand does become more important as certain brands employ newly patented technology to attain said efficiency tiers.
The most important aspect in purchasing a new HVAC system is the contractor. Let me repeat that… the most important aspect in purchasing a new HVAC system is the contractor.
Please contact your local qualified HVAC contractor for more specifics. Cheers!
