“Exceptional Emergency HVAC Service – Highly Recommend!

I recently had an emergency situation when my air conditioning stopped working right at the beginning of a brutal summer heat wave. Thankfully, I called Foundation Heating and Air LLC, and they responded with incredible speed and professionalism. Within an hour of their arrival, my AC was back up and running — an absolute lifesaver in the sweltering heat!

From start to finish, my experience with Foundation Heating and Air was outstanding. Their team was punctual, courteous, and highly efficient. The technicians arrived well-prepared, quickly diagnosed the issue, and had the necessary tools and expertise to resolve the problem on the spot. It was clear they take pride in their work and genuinely care about their customers' comfort and safety.

What stood out most was their time efficiency and excellent customer service. In an industry where delays and vague timelines are common, it was refreshing to work with professionals who respected my time and communicated clearly.

I’m extremely satisfied with the service I received and would highly recommend Foundation Heating and Air LLC to anyone in need of air conditioning repair in Montgomery County, MD. They’ve earned my trust, and I wouldn’t hesitate to call on them again.“
