Make-Up Air Unit Installation, Maintenance, and Repair Services

Balanced Indoor Air. Optimized System Performance.

At Climico , we provide full-service solutions for make-up air units, critical components that keep your commercial environment safe, healthy, and HVAC-efficient. Whether you operate a commercial kitchen, industrial plant, retail location, or large facility, make-up air systems are essential to maintaining air balance, preventing pressure problems, and supporting a well-functioning exhaust system.

We offer expert installation, proactive maintenance, and responsive hvac repair services designed to extend equipment life and improve overall building performance.

Why Make-Up Air Units Are Essential for Most Commercial Buildings

Modern commercial buildings rely heavily on exhaust systems – kitchen hoods, industrial vents, bathroom fans, and HVAC systems, all of which remove large volumes of air. Without a make-up air unit to replace that air, you end up with negative pressure, which can disrupt HVAC system efficiency, cause backdrafting of combustion appliances, and lead to uncomfortable drafts and uneven temperatures.

This imbalance can also compromise indoor air quality, pulling in unfiltered air through door gaps or wall penetrations. Make-up air units solve these issues by introducing filtered, tempered outdoor air into your facility, maintaining proper airflow and supporting compliance with ventilation codes and health regulations.

Make-Up Air Unit Installation

Installing a make-up air unit isn’t just about connecting ductwork, it’s about designing for performance, compatibility, and compliance. At Climico , we design and install make-up air systems for commercial kitchens, warehouses, laboratories, healthcare facilities, and more.

We begin by conducting a detailed site assessment and airflow analysis, then select the right unit based on your pressure requirements and exhaust loads. Our team ensures proper installation of heating or cooling features if needed, integrates the system with existing HVAC controls, and balances airflow for smooth operation. Every installation is completed to meet safety codes and ventilation standards.

Make-Up Air Unit Maintenance

Preventative maintenance is critical to keeping your ventilation system operating at peak efficiency. Our maintenance programs are designed to extend the life of your equipment, reduce energy use, and prevent disruptions, especially in high-demand environments like commercial kitchens and manufacturing plants.

We inspect filters, fans, and motors, replacing or cleaning components as needed to maintain proper airflow. We also clean heating and cooling coils, lubricate moving parts, and calibrate system controls. In addition, we check motor amperage and test thermostats and actuators to ensure every part of the system is functioning properly. By catching wear and inefficiencies early, we help you avoid expensive repairs and unplanned downtime.

FAQs for Make-Up Air Unit Services

What is a make-up air unit and why is it important?

A make-up air unit brings in fresh outdoor air to replace air that’s been exhausted by fans or hoods. This prevents negative pressure, protects indoor air quality, and keeps exhaust systems functioning properly.

How do I know if my building needs a make-up air unit?

If your building has strong exhaust ventilation (like in kitchens or workshops), you may experience pressure imbalances, drafts, or backdrafting without a make-up air unit. Our team can assess your space to determine the right solution.

How often should a make-up air unit be maintained?

We recommend at least annual maintenance, though facilities with high ventilation demand may benefit from bi-annual inspections. Regular service improves energy efficiency and extends system life.

What are signs that my make-up air unit needs repair?

Look for poor airflow, unusual noises, inconsistent indoor temperatures, or higher energy bills. These can all indicate an issue with your make-up air system.

Can you install a make-up air unit in an existing building?

Yes. Our team specializes in retrofitting make-up air systems into existing commercial buildings with minimal disruption to your operations.

Do make-up air units offer heating or cooling options?

Yes. Many units include gas, electric, or hydronic heating, and some also integrate cooling to condition incoming air. We’ll help you choose the right configuration.
