Lighthouse HVAC: Where Integrity Guides Every Repair.

Ronnie Masgay remembers a service call he went on several years ago where the HVAC company he was working for wanted to sell a homeowner a new $20,000 furnace. The customer, a woman with her son, was clearly distraught by sticker shock, sitting at her kitchen table and crying. 

“I later went back and took a look at her furnace on my own and saw that she really only needed a fuel filter and nozzle replaced,” said Masgay. “I fixed her furnace for $400 instead of replacing it, and it is still running to this day!” 

That’s when Masgay decided to start his own HVAC company. Seeing the unethical practices of many of his competitors, he wanted to do things differently. Instead, he built a company based on the values of integrity, honesty, and safety.

Today, Lighthouse HVAC is a family-owned business and team of 5 that will go above and beyond to ensure better livability, air quality, comfort and safety for your home or office.

  • Protect your system and prevent costly breakdowns. Improve system longevity and energy efficiency with convenient maintenance plans.

A Signal of Safety and Reliability

The name “Lighthouse” was inspired by Masgay’s father, who was a waterman in Edgewater, MD with deep ties to the Chesapeake Bay. Influenced by watershed culture growing up, Masgay chose “Lighthouse HVAC” as more than just a name. It’s also a signal of guidance, safety and reliability, just like an actual lighthouse. 

Here’s a tell-tale sign that Lighthouse HVAC values preventive maintenance, thoroughness, and responsibility. Rarely conducted by other HVAC companies, Lighthouse HVAC performs load calculations when replacing units. This helps them ensure that AC or heating units are properly sized based on your home’s layout, insulation, or any updates over time. Units that are too large don’t last as long and can make homes more humid, leading to discomfort or other unsafe conditions, like mold. 

“I want to improve the air quality and experience for my customers so they have the best and the healthiest indoor air setup,” said Masgay.
