Sid Harvey's Commitment to A2L-Compatible A/C Units
At Sid Harvey, we're proud to offer a full lineup of A2L-compatible air conditioning condensing units, evaporator coils, and package units.
Why A2L?
A2L refrigerants are gaining popularity in HVAC systems due to their lower global warming potential (GWP), along with reduced toxicity and flammability compared to other refrigerant types. These units are not only environmentally friendly, but they also offer improved energy efficiency—making them a smart, future-focused choice.
Whether you're upgrading your current system or working on a new installation, trust Sid Harvey to deliver the reliable, efficient A2L-compatible equipment you need.
When it comes to A2L condensing units, think Sid Harvey—your trusted partner in HVAC.
