FAQs

  • Do you provide HVAC design for renovations or additions?

    Yes. We perform load calculations, size equipment correctly, and design ductwork/ventilation to match the new layout.

  • Can you service commercial rooftop units (RTUs) and make-up air?

    Absolutely. We install, replace, and maintain RTUs, MUA, ERV/HRV systems, and integrate controls.

  • How often should HVAC equipment be serviced?

    Typically annually; twice per year (spring/fall) is ideal for systems that heat and cool. Regular maintenance extends lifespan and reduces breakdowns.

  • Do you install ductless mini-splits?

    Yes — single and multi-zone systems, including cold-climate heat pumps for efficient heating and cooling.

  • Can you help improve indoor air quality?

    We design ventilation + filtration solutions (HRV/ERV, HEPA/MERV filters, UV-C, humidity control) to address dust, odors, and moisture.
