Family-Owned HVAC Contractor Serving Montgomery County Since 1986

Carl j Wendler heating and cooling was founded by Carl Wendler, a Southeastern PA local who grew up here, went to school here, and started his family in this community.

We treat every customer like family, clean up when the job is done, and don’t consider the work finished until our customers are happy. We also actively work to protect our customers from dishonest contractors and HVAC scammers.

Collegeville Air Conditioning Services

Collegeville’s humid summers push cooling systems hard, and when your AC struggles, you need fast, knowledgeable help. 

Our NATE-certified technicians handle the full range of cooling work: 

• Repair
• Installation and replacement
• Preventive maintenance

We also install, maintain, and repair ductless mini-split systems, including models with advanced zone control and built-in filtration. Ductless mini-splits are an excellent fit for Collegeville homes without existing ductwork, home additions, or rooms that need independent temperature control.

For installations and replacements, we provide tiered quotes with honest guidance on what fits your home and lifestyle. We explain energy use, available rebates, and system fit, and we don’t push you toward upgrades that don’t make sense for your situation.

Pennsylvania winters demand heating systems that perform reliably through extended cold stretches. Our team handles repair, installation, and maintenance for furnaces, heat pumps, and boilers, and our 24/7 emergency heating repair means a failure during a cold snap won’t leave your family waiting. 

For new installations, we provide tiered quotes with guidance on energy-saving options and what system genuinely fits your home. No upselling for its own sake.

If your home’s air quality concerns you, reach out, and we’ll assess what’s actually going on before recommending anything.
