Cleveland, OH

Plumbing, Heating & Cooling Services for the Greater Cleveland Area

Since 1905, AJ Parker Plumbing & Heating has been a cornerstone service provider supporting Northeast Ohio’s homeowners and small business owners. What began with OD Parker serving his neighbors from a single location has grown into a six-generation family business that’s earned the trust of Cleveland-area homeowners for over 120 years. We bring local expertise and honest service to every job we complete.

Heating Cleveland Area Homes Since 1905

Cleveland winters demand reliable heating systems, and we’ve been keeping area homes warm since before most companies in this business even existed. We install, repair, and maintain all types of furnaces and boilers, working with every major manufacturer and bringing special expertise to Rheem and Ruud equipment. Scheduling annual maintenance before winter hits helps you avoid expensive emergency calls when it’s 10 degrees outside, and when breakdowns do happen, our 24/7 emergency service responds quickly to restore your heat and comfort.

Cooling Services for Cleveland Summers

Lake Erie’s influence on Cleveland weather means summers bring heat and humidity that test your air conditioning system. We install properly sized central AC systems designed for your home’s specific square footage and layout, maintain existing equipment to maximize efficiency and lifespan, and repair systems when they fail. For Cleveland’s many older homes without existing ductwork, or for spaces needing independent climate control, ductless mini-split systems provide energy-efficient cooling without requiring extensive renovations. Regular maintenance keeps your system running at peak performance and helps prevent those surprise failures on the hottest, most humid days of summer.

Complete Plumbing Services

Cleveland-area homes face diverse plumbing challenges, from aging pipe infrastructure in older neighborhoods to modern systems in new construction. We handle everything from routine repairs and fixture installations to serious emergencies like burst pipes and sewer backups. Our 24/7 emergency service means you can reach real people immediately when disaster strikes, and we install and service both traditional tank water heaters and modern tankless systems, helping you choose the right option for your home’s needs and your budget. Our leak detection technology can locate hidden problems in walls, foundations, and underground lines before they cause extensive damage to your property.

Backflow Testing & Prevention

Protecting Cleveland’s drinking water supply is a serious responsibility, and backflow prevention devices play a critical role. These devices stop contaminated water from flowing backward into clean water lines—a particular concern for properties with irrigation systems, commercial connections, or certain plumbing configurations. We install backflow prevention devices that meet all local codes, perform the annual testing many Cleveland-area municipalities require, and handle all documentation to keep you compliant with regulations while ensuring your drinking water stays safe.

Boiler Expertise for Cleveland Homes

Many of Cleveland’s older neighborhoods feature homes with boiler heating systems, and these require specialized knowledge that many modern technicians simply don’t have. We’ve worked on every type of boiler system over our 120 years in business—from century-old cast iron radiators to state-of-the-art condensing boilers. Whether you need annual maintenance to keep your system running reliably through another winter, emergency repairs to restore heat quickly, or honest advice about whether replacement makes better financial sense than another major repair, we provide straight answers based on what’s actually happening with your equipment and what will serve your home best long-term.
