Lexington HVAC questions, answered
Are your technicians licensed and insured?
Every technician dispatched into Lexington is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
Do you service commercial and light commercial properties?
Yes. Around Lexington we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
How often should I change my filter in 02420?
Monthly inspection and replacement every 60 to 90 days is the baseline. Homes in Lexington with pets, ongoing construction nearby, or a high-MERV filter in an undersized return should move to monthly changes. A loaded filter is the single most common cause of frozen coils and failed blower motors.
Why is my system short cycling?
Short cycling in Lexington most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
Do you offer maintenance plans?
We do. A two-visit plan in Massachusetts covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
