Residential hydronic boilers power whole-home baseboard radiators, fan coils, and domestic hot water systems with steady, radiant heat. A sudden boiler lockout during sub-freezing weather threatens frozen pipes and severe household freeze damage. Our boiler mechanics in University Park, Maryland troubleshoot both traditional atmospheric cast iron boilers and modern modulating-condensing wall-hung combi units. We test electronic ignition modules, clean soot and scale from heat exchangers, replace leaking circulator pumps, and calibrate aquastat limit controls for reliable winter warmth.

Real Numbers From Over A Decade Of Trade Service.
Real Reviews From Homeowners And Businesses We Have Helped Across The Area.
At 2:30 AM on a freezing night, our main water stack cracked wide open in the basement. Water was gushing everywhere. EPS PRO's answered immediately and had a master technician at our door in 22 minutes. He isolated the municipal feed, cut out the ruptured line, and soldered in clean copper before sunrise.
We had three separate drain companies attempt to clear our kitchen sewer line, but the line kept backing up every weekend. The crew from EPS PRO's brought a high-pressure hydro jetter with a self-leveling camera. They emulsified years of heavy grease and showed us the clean pipe on video.
Our restaurant had an active grease trap overflow during a Friday dinner rush. I called EPS PRO's in a panic. The technician arrived with heavy vacuum pumping gear, cleared the baffle blockages, and sanitized the area within 45 minutes. They saved our entire weekend revenue.
