We Cover All Variables for Your HVAC Installation
When we install an HVAC system, we review all possible variables. Some of the factors considered when determining the correct HVAC equipment include:
- Total square footage of the facility
- Space usage – offices, meeting rooms, manufacturing, storage, etc.
- Zoning requirements – allows for more individual control in separate areas of the facility
- Special temperature-controlled environments – computer rooms, etc.
- Special environmental conditions – clean rooms for electronics manufacturing, paint rooms, etc.
- Humidification / de-humidifier requirements – indoor swimming pools, school gymnasiums, etc.
- Air purification / filtration needs – hospitals, healthcare facilities, nursing homes, bar & grills, etc.
Marsh Heating & Air Conditioning also offers a Maintenance Program for our commercial customers to ensure that their equipment keeps running at peak performance.
Commercial Maintenance Plan
How does maintenance help your business? The best way to keep everyone in your building safe and comfortable while reducing costs is to prevent problems before they happen. We can help your business do that with a thorough HVAC inspection by our highly qualified technicians.
Our maintenance visits can be arranged between one and four times annually. We will clean and inspect your system, lubricate equipment, clean coils, check electrical wiring, calibrate controls, and check for early signs of wear and tear. Additionally, if requested we can replace air filters and belts.
We can expertly handle the following equipment:
- Rooftop heat/cool units
- Air cooled and water-cooled heat pumps
- Clean rooms, computer rooms, smoke-free rooms
- Specialty humidification (including steam)
- Refrigeration
Make-up air units and ventilation systems
Furnace and air conditioner split systems
Engaging in a commercial preventative maintenance contract ensures that your HVAC equipment is thoroughly inspected on an annual basis (as recommended by all equipment manufacturers) so it will operate at optimal performance providing efficiency and safety. HVAC equipment that operates efficiently reduces your energy costs and prolongs equipment life to ensure maximum safety and economy as well as improving air quality.
We offer a discount on parts and services for customers who take advantage of our maintenance program. Please call us for more information.
