Leach-Remmers Heating & Air

At Leach • Remmers Heating & Air Conditioning, we start by listening. We serve customers in the Jacksonville, Illinois area with a full range of heating and cooling products and services, without high-pressure sales tactics or gimmicks. Our founders, Jeff Leach and Gary Remmers, believe in looking out for our customers’ best interests. We give each customer our full attention and provide clear, honest information so they can make an informed choice about a repair or replacement. We recommend practical solutions that can reduce energy use, improve comfort, and lower heating and cooling costs.

We repair and replace electric and gas furnaces, boilers, heat pumps, and air conditioning systems for homes and businesses. When a new system is needed, we offer a free assessment and design the system around the property, situation, and budget. We also install and service geothermal systems, provide ductless mini-split solutions for one or several rooms, and offer indoor air quality products and dehumidifying. Our in-house ductwork shop allows us to custom-fabricate duct systems precisely and efficiently, while our crew carefully plans installation work to help keep each project on schedule.

Preventive care is another important part of what we do. During spring and fall maintenance visits, we inspect and clean heating and air conditioning equipment to enhance performance and help prevent costly breakdowns. We also offer annual preventive maintenance plans designed to keep equipment running smoothly throughout the year. For new homes and additions, we design heating and cooling systems and manage the project from planning through installation. Across every service, we focus on maximizing efficiency, controlling comfort costs, adding value, and treating our customers with fairness and respect.
