Key maintenance tasks include:

  • Air Conditioner Systems:

    Regular checks to ensure they are cooling spaces efficiently without overuse, which helps avoid excessive energy consumption and wear on the system.

  • Heating System Systems:

    Inspections of Furnace and the flue pipe, or heat pump are critical for safe operation and optimal performance, especially during colder months.

  • Chiller air and water cooled

    Quarterly Chiller maintenance with a checklist is important to help prevent a breakdown, chillers condensers should be taken apart, cleaned and treated, in conjunction with cooling tower if its a water operated chiller.

  • Water Towers (Cooling Towers)

    Water towers need to be inspected, cleaned and repaired as needed with a quarterly maintenance, for maximum efficiency.

  • Ventilation Equipment

    Maintenance of ventilation systems is vital for maintaining indoor air quality and proper air flow.

Properly maintained HVAC systems not only extend the lifespan of the equipment but can also improve air quality and reduce energy costs by ensuring all components are running at peak efficiency.

Ensuring the efficiency and longevity of your commercial HVAC system through regular maintenance is not just a recommendation; it’s a necessity. By staying proactive about maintenance, you can significantly reduce the risk of costly downtime and repairs, while maintaining an optimal working environment for both employees and customers.

I run a restaurant, bakery and deli. We have 3 large walk in refrigerators, 2 freezers and about 10 other refrigerated units. It’s a big operation and I have used several companies over the years. I came across American Cool Heat & commercial refrigeration about 4 years ago. They are the most thorough and honest company I have worked with in 19 years of operation. I love that they warranty their work and explain everything to me. The owner, William, had me go on the roof with him to check out our refrigeration rack and explain each part, I made videos for reference. Our equipment was out dated and needed to be serviced. He showed me several areas where poor work had been done by other companies. His techs are friendly, efficient and professionally trained, I never have to guess or ask questions, they always clearly explain everything to me and give me some options depending on the job. They are replacing a defrost timer and condensing fan in my walk in freezer today. Whenever I call for service, they come the same day- even emergencies on weekends. Can’t say enough good things about this company. Ask for William!

We have a large business in Palm Springs. William and his team came highly recommended. From day one, they did the impossible. This includes rebuilding a 20-ton HVAC unit on our roof that was written off by other companies. Competitors wanted to remove it which included a crane, insurances, and of course the replacement cost. William, Frank, and the team assessed the unit, and gave us a 90% success rate on a repair vs. a replacement. They succeeded. From then on, they’ve handled all or our equipment… on time, up front, and always professional.

Common Questions about Commercial HVAC maintenance


This typically varies from location to location and equipment set up. We recommend at least twice a year , but if you notice efficiency dropping or air quality issues, that is a sign you may need your HVAC system maintenance more frequently.
The most apparent sign is Decreased Air Quality and Airflow. Other signs can include higher than normal energy usage due excessive system run time, Hot or Cold spots in the conditioned spaces,
Yes, by keeping the HVAC systems clean, and making sure all the system components are optimized and working properly, you will notice improved performance and energy efficiency.
We clean the outdoor coils in system is a heat pump, check the air filters, make sure the thermostat is working properly, perform a visual inspection of all electrical components in the Furnace or Heat Pump, Check pressures and temperatures on Heat Pumps, and on furnaces we check the operation of the furnace.
The most common issue is dirty air filters. Dirty air filters not only affect air quality, but also the system performance of the ventilation. Air travels through the path of least resistance, this means if there are any gaps or openings in the return duct, air will bypass the air filters and dirt will enter the ducts and be distributed through the conditioned spaces, and even worse, this dirt will start to obstruct the indoor coil, and slow down air flow which will can freeze your coil while in cooling mode, and trip safeties in heating mode.
Neglecting HVAC maintenance will result in reduced system performance, and in extreme cases can cause system failure or put the occupants health at risk.
This also varies, it can be as little as 1 hour, or several hours depending on the complexity of the HVAC system, the quantity of the units being maintenanced, and building layout.
Yes, by maintaining the HVAC system in proper intervals, the system remains performing optimally through its life and breakdowns are less likely to occur. When a HVAC system breaks down it not only affects your operational cost, but also the experience of the occupants.

– Hvac Repairs are needed when there is a breakdown, or the HVAC unit is not performing as it should.
– Hvac Maintenance goes by different names, Maintenance, Preventative Maintenance, System Tune up. The objective is to maintain the system so it is always at peak performance.

Yes, the different seasons impact HVAC systems differently. In the hot summer months, HVAC systems have the most stress in the condenser units that are typically outside in direct sun exposure, Focus in summer months is on the condenser. In winter months, heat pumps also rely not only on the outdoor coils, but also defrost circuits which are on heat pump units. Furnaces don’t use the outdoor coil, and focus is on the Furnace and ventilation system.
