Claim This BusinessLamco Systems Inc has earned a 4.7-star rating across 99 reviews while serving Tyngsborough, Massachusetts, and surrounding Middlesex County communities. The contractor operates standard business hours Monday through Friday from 8 AM to 4 PM, providing installations, replacements, and service calls for residential heating and cooling systems. Based in Tyngsborough, the team responds to calls throughout the greater Lowell area, including nearby towns where homeowners seek responsive local technicians.
Customers repeatedly note Lamco's thorough communication before, during, and after each job. Reviewers describe technicians who explained building-code changes, compared furnace stages, and recommended systems suited to each home's specific needs rather than pushing upgrades unnecessarily. Several reviews specifically mention cleanup protocols, with crews vacuuming carpets and hauling away old equipment after completion. This attention to detail during the finishing phase distinguishes the company from contractors who consider a project complete once equipment fires up.
John Guilfoyle's review describes a same-weekend replacement of a 25-year-old gas furnace and AC unit, with Skip and Howard completing both changeouts in a single visit and explaining each step as work progressed. Davida Gilmore's experience highlighted Tyler and Fernando arriving to install a complete heating and air conditioning system, leaving a new thermostat and answering every question before departing. Mike Rugg noted that Chris provided three competing quotes before recommending Lamco for its competitive pricing, and that original installers Tyler and Fernando left a spare filter with the system.
Technicians Chris, Skip, Howard, Tyler, and Fernando appear across positive reviews for their diagnostic knowledge and cleanup thoroughness. Negative feedback centers on post-installation filter maintenance guidance, with one reviewer noting the original crew did not emphasize how quickly filters accumulate buildup in newer systems. Positive reviews uniformly mention same-week scheduling and equipment explanations tailored to each household.
