Frequently Asked Questions
Answers to common questions from property managers, building owners and facility teams about maintenance, repairs and replacements.
How often should commercial HVAC systems be serviced?
Most commercial HVAC systems should be professionally maintained two to four times per year, following the manufacturer’s recommendations, so cooling is ready before summer and heating is ready before winter.
What is included in a commercial HVAC maintenance agreement?
Our preventive maintenance agreements are customized to the equipment in your building. Visits typically include scheduled inspections, cleaning, adjustments and testing, with every unit maintained to the manufacturer’s specifications.
How do I know if equipment should be replaced instead of repaired?
Signs include frequent breakdowns, uneven temperatures, rising energy bills, or equipment older than 10 to 15 years. An inspection shows whether a repair or an in-kind replacement, matched to your existing infrastructure, is the better investment.
Do you bid plan and spec renovation projects?
Yes. We bid tenant fit-outs, white-box renovations and retrofits from your engineer’s mechanical drawings and install exactly as drawn, coordinating with the general contractor throughout.
What equipment do you service?
Rooftop and packaged units, VRF systems, water source heat pumps, PTAC units, commercial split and ductless systems, computer room AC (CRAC) units, cooling towers, and exhaust fans, in commercial and luxury apartment buildings across Manhattan, Queens and Brooklyn.
Can HVAC maintenance improve indoor air quality?
Yes. Regular maintenance improves indoor air quality by replacing dirty filters, cleaning system components, and ensuring proper airflow. A well-maintained system reduces dust, allergens, and airborne contaminants for healthier, more comfortable buildings.
