TwinTech LLC

TwinTech LLC operates as a heating contractor in McLean, Virginia with a 4.6-star rating drawn from 31 customer reviews. The company serves the broader Northern Virginia region, including McLean and surrounding communities, delivering both residential and light commercial HVAC solutions. Brothers Eric and John Glowacki established this family-owned enterprise in 2006, and both holding Virginia Master Mechanical Licenses along with nearly 60 years of combined industry experience. Their team provides installation, maintenance, and repair services across all major heating and cooling brands, supported by continuous service improvement training.

What distinguishes TwinTech is their investment in specialized systems and round-the-clock availability. They install UNICO high-velocity duct systems, a solution particularly suited to older homes where conventional ductwork would compromise interior aesthetics. Their portfolio includes ductless mini-split systems, hydronic boilers, and whole-house humidity control equipment, addressing the dry winter air common to the Mid-Atlantic. Notably, they maintain a fleet of four-wheel-drive service vehicles ensuring they reach customers during severe weather events. This capability complements their 24-hour emergency service, a practical resource when heating fails on frigid nights.

Customer narratives from verified reviews illustrate their operational approach. During the year's most intense heat wave, technician Eric diagnosed a system's failure after two other contractors proposed full replacements, he repaired it at a reasonable cost. Another reviewer recounting a gas furnace replacement noted TwinTech's methodical approach: attempts to source a part failed due to the unit's age, prompting a full replacement with transparent pricing and meticulous cleanup. These accounts align with recurring praise in reviews describing respectful on-site behavior and thorough post-job housekeeping.
