HVAC Services in Broomall, PA

Family-Founded, NATE-Certified Heating & Cooling Since 1986

Carl j Wendler heating and cooling has served Broomall and the surrounding Delaware County communities since Carl Wendler founded the business in 1986. Carl grew up in Southeastern PA, went to school here, and started his family here before launching Carl j Wendler heating and cooling after years of working for larger HVAC companies. His goal was simple: give back to the neighborhood that shaped him. Nearly four decades later, that same commitment drives every service call, installation, and tune-up we complete.

Our team includes NATE-certified technicians who are fully trained, licensed, bonded, and insured. NATE certification (North American Technician Excellence) is the industry’s leading credential for HVAC technicians, meaning the person working on your system has passed rigorous third-party testing. We handle residential and commercial work across heating, cooling, heat pumps, boilers, furnaces, mini-splits, and indoor air quality systems. 

Why Broomall Homeowners Choose Carl j Wendler heating and cooling

Local Air Conditioner Services

When your air conditioning struggles through a Pennsylvania summer, relief disappears fast. Our AC repair technicians identify issues with any component, including the compressor or air handler, and fix them correctly the first time. Licensed professional service also protects your equipment warranty, since many manufacturers require a licensed contractor for coverage to remain valid.

If an upgrade is in order, we handle precise AC replacement and help you select a unit sized to your home’s actual cooling needs, not just the biggest system on the shelf. We also offer regular tune-ups to inspect your whole system and catch minor issues before they become major ones.

Complete Heating Solutions

With our decades of know-how, you can have total confidence in turning to us for all things to do with heating, including the following. 

Furnaces

Our technicians handle furnace maintenance, furnace replacement, and furnace repair with open communication and focused attention. If your system blows cool air, makes unusual noises, or struggles to match your thermostat, we find the cause and fix it, whether that’s airflow loss, ignition failure, or worn parts.

When repair costs exceed the value of fixing an aging system, replacement makes more sense. We help you choose between gas and oil furnaces based on your property’s existing fuel connections and long-term energy goals. 

Boilers

From fast and effective boiler repairs to much-needed upgrades, we're your go-to for all things to do with these complex systems. No matter the job, we back our work with a commitment to achieve your complete satisfaction.

Heat Pumps

Heat pump systems provide both heating and cooling efficiency, which can significantly reduce energy costs. If you’re considering a new installation, we guide you through the process with straightforward answers, helping your system fit your space, work with your thermostat, and run efficiently.

Additionally, our technicians provide repairs for both common and complex problems, including low refrigerant, worn motors, and faulty sensors. 

Ductless Mini-Split Systems

Carl j Wendler heating and cooling installs, maintains, and repairs ductless mini split systems, including those from Mitsubishi Electric. These systems provide both heating and cooling without connecting to ductwork, making them the right answer for spaces a central system can’t reach. 

Indoor Air Quality Services

True home comfort goes beyond the number on your thermostat. The air your family breathes can carry dust, pollen, and other irritants that circulate through your duct system, and humidity adds another layer. The heavy, sticky air of a Pennsylvania summer makes your home feel warmer and less comfortable than it should. Managing these elements is fundamental to a healthy living space.

We offer practical solutions to clean and balance your indoor air. An air purifier connects directly to your HVAC system to capture and remove airborne contaminants. A whole-home dehumidifier removes excess moisture, making the air feel fresher throughout the season. Proper ventilation exchanges stale indoor air with fresh outdoor air. 

Our technicians evaluate your home’s specific needs before recommending anything, so you’re not paying for equipment you don’t need. Visit our indoor air quality page or call us to find out what fits your home.

Commercial HVAC Services

Commercial HVAC systems run under higher duty cycles than residential units and require contractors who understand the load and control differences involved. Our NATE-certified technicians have experience with the systems that power retail stores, offices, and other commercial buildings across the Broomall area. We provide the maintenance, repair, and installation services your business needs for uninterrupted operation.
