C. G. Egli INC

C. G. Egli INC has kept Dayton homes warm since establishing the business at 515 Springfield Street in the Pleasant Hills neighborhood. The company specializes exclusively in steam heating systems, maintaining and restoring vintage radiators and boiler setups that many contractors shy away from. All seven customer reviews award a perfect five-star rating, with clients praising the team's ability to extend the life of systems exceeding a century in age. The company serves residential neighborhoods throughout the Dayton metro area and maintains a full-service operation weekdays from 8 a.m. to 5 p.m.

What distinguishes C. G. Egli from other HVAC contractors is their deep expertise in steam heat, a technology that many modern technicians never learned. Their website displays documented efficiency comparisons showing residential steam systems returning 84.4% of fuel value, outperforming hot water baseboard and forced air alternatives. The team explicitly welcomes older homes requiring period-accurate repairs alongside modern upgrades, a combination rarely offered by mainstream HVAC companies. They also handle commercial properties, having resolved temperature problems for Holy Family Church where some rooms overheated while others remained cold.

Three reviewers specifically name the technicians who solved their heating problems. Christian and his crew maintain a 100-year-old system for one homeowner, keeping it operating at peak performance through regular service. Another client praises Cody for executing a repair so quickly it seemed to happen faster than a blink. A third customer notes the team arrived same-day during an emergency, demonstrating the rapid response that earned the company a perfect five-star average across all feedback.
