About Our Comprehensive Heating System Services

In chilly Central Maryland winters, homeowners and small businesses need professional, high-quality HVAC services to keep their indoor spaces comfortable. At Exxel Mechanical Services, we provide our customers in Mount Airy, MD and the surrounding areas with service that exceeds expectations. Our licensed technicians offer repairs, replacements, and maintenance to ensure your home stays warm throughout the cold winter months.

24/7 Reliable Heating Repairs

When your heat breaks down during the winter, repairs can’t wait. That’s why our technicians work 24 hours a day, 7 days a week to provide emergency services for any HVAC issue you’re facing. We repair all makes and models of heat pumps, furnaces, and boilers with expert services done right the first time.

Expert Heating Installation

Even with the best care, every home will eventually need a heating system replacement. Our experienced HVAC technicians will walk you through our comprehensive installation services. From choosing a new system to installing it, we tailor our recommendations so you know you’ll get the right fit for your unique home and budget.

Saving You Money on Your Heating Install

There’s no way around it – new heating systems are a big investment for most families. Therefore, when you work with Exxel, we ensure your new installation comes with a manufacturer warranty that will protect it for years. We also offer generous financing options to upgrade your system without breaking the bank.

Proactive Heating Maintenance

Regular maintenance on your furnace, boiler, or heat pump will maximize its longevity and ensure it functions properly. Maintenance also ensures greater efficiency and lower energy bills. That’s why our team offers comprehensive heating maintenance services for our residential and commercial customers.

Our Heating Maintenance Plans

While we provide single maintenance appointments you can schedule any time, Exxel Mechanical Services also offers Silver and Gold maintenance plans for consistent care and extra benefits! Both heating maintenance plans include an annual inspection and priority next-day service to keep your heater running efficiently all season.
