Practical, Effective Service

G&R is owned and operated by Greg Zarris and Rob Serpico, and our mission is to bring practical, down-to-earth advice to air conditioning repair and replacement, furnace repair and installation, and sump pump and water heater replacement. Our unique logo represents us, with Greg as the gator and Rob as the rhino. We want you to feel confident that you’ve made the right choice in calling us; we are fully licensed and insured, and we offer a complete one-year warranty on all of our work. We know how important your heating and cooling systems are; when they’re not working properly, your home can quickly become very uncomfortable.

As a family-owned company, we strive to treat each customer like family and we are never satisfied until you are. If there’s an emergency, we’ll be there as soon we can to take care of it. If there’s a lingering issue after we’ve been there, we’ll come back and fix it. We’re available 24/7 to take your calls and tackle your HVAC problems. If your AC simply won’t turn on, or the entire house is freezing because the furnace won’t climb above 60 degrees, contact us right away. You shouldn’t have to wait for expert service!
