A+ HVAC and Refrigeration is a family-owned company providing expert heating, cooling, and commercial refrigeration service to Naperville and the surrounding Illinois communities. Since 2015 we've built our reputation one honest repair at a time, earning a 4.9-star rating across more than 1,282 Google reviews from local homeowners and business owners.
When your comfort system fails in Naperville, you need a team that answers fast, diagnoses accurately, and fixes it right the first time. That's exactly what we deliver — with same-day appointments on most repairs, honest flat-rate pricing you approve before we start, background-checked technicians, and a full warranty on every job. From furnace and air conditioning repair to walk-in coolers and commercial refrigeration, we're the local team Naperville counts on.
Naperville homeowners rely on us to keep their families comfortable in every season. In the summer, our air conditioning repair, maintenance, and installation services keep central and ducted systems running efficiently through Illinois heat waves. In the winter, our furnace and heating experts handle everything from a furnace that won't ignite to a full high-efficiency system replacement.
We understand that a heating or cooling breakdown is stressful, especially with young children or older family members at home. That's why we prioritize fast response and clear communication. We'll explain what's wrong in plain language, give you an upfront price, and get your home comfortable again — usually the same day. And because we price per repair instead of by the hour, you'll never watch the clock or worry about a padded bill.
For Naperville businesses — restaurants, grocery stores, cafes, and facilities — downtime is lost money and, with refrigeration, a food-safety risk. Our commercial team services walk-in coolers, walk-in freezers, reach-in units, prep tables, display cases, and rooftop cooling with the urgency your operation demands.
We know a warm walk-in or a down rooftop unit can't wait until tomorrow, so we respond quickly and carry common parts to finish most repairs on the first visit. Whether you need emergency refrigeration repair to save your inventory or a maintenance plan to prevent breakdowns during your busy season, we keep Naperville businesses running with fast, reliable, fully-warrantied service.
A+ HVAC and Refrigeration is a true one-call solution for Naperville. On the cooling side, we handle air conditioning repair, seasonal AC maintenance, and new high-efficiency AC installation for central and ducted systems. On the heating side, our team takes care of furnace repair, comprehensive heating maintenance, and full heating system installation to keep you warm through the Illinois winter.
For Naperville's restaurants, groceries, and facilities, our commercial refrigeration expertise covers walk-in cooler repair, walk-in freezer repair, and all types of commercial refrigeration — from reach-in units and prep tables to display cases. Because we cover the full spectrum of heating, cooling, and refrigeration under one roof, you get a single trusted partner for every comfort and cooling need at your Naperville property, backed by the same fast response and full warranty on every job.
Our technicians see the full range of heating, cooling, and refrigeration issues across Naperville. Some of the most common calls we handle include:
There are plenty of HVAC companies in Illinois, but Naperville residents and businesses keep choosing us for a few simple reasons. We're fully licensed and insured, every technician is background-checked, and we treat your home or business like our own — leaving your space cleaner than we found it.
Our pricing is honest and upfront: a flat rate per repair with no hidden fees, a diagnostic fee that's waived in full when you proceed with the work, and a free service call with any repair. Every job is backed by a full warranty — most parts for 12 months and labor for 30+ days. Add same-day service and a genuine commitment to doing the job right, and it's easy to see why we've earned the Angi Super Service Award, Thumbtack Top Pro status, and BBB accreditation.
Illinois weather is hard on comfort systems, and Naperville is no exception. Brutally cold winters push furnaces and boilers to their limits, while humid summer heat waves force air conditioners to run for hours on end. That constant demand is exactly why seasonal service matters so much here. A furnace tune-up in the fall catches worn igniters and cracked components before the first freeze, and an AC tune-up in the spring restores efficiency before the July heat arrives.
For Naperville businesses, refrigeration runs year-round with no off-season — a walk-in cooler or freezer can't take a day off. We help local restaurants and shops stay ahead of failures with proactive service and fast emergency response. Whatever the season, our goal is to keep your Naperville home or business comfortable, safe, and running efficiently, so you're never caught off guard by a breakdown at the worst possible moment.
We know that inviting a contractor into your Naperville home or business requires trust, and we don't take that lightly. Every technician we send is licensed, insured, and background-checked, and we treat your property with respect from the moment we arrive. We'll walk you through the diagnosis, show you what we found, and give you clear options — never scare tactics or pressure to replace something that can be repaired.
That honest approach is why so many of our Naperville customers become repeat clients and refer their friends and neighbors. With a 4.9-star Google rating, the Angi Super Service Award, Thumbtack Top Pro status, and BBB accreditation behind us, you can feel confident you're hiring a team that will do right by you.
