HVAC stands for Heating, Ventilation, and Air Conditioning. It's the technology of indoor comfort, designed to control the temperature, humidity, and purity of the air. At National Aircondition, we specialize in all three aspects for both commercial and residential properties.

We recommend a comprehensive service at least once a year. For systems in heavy use, like in Mumbai's commercial offices, servicing twice a year is ideal to ensure optimal performance and prevent breakdowns.

A **Split AC** has a wall-mounted indoor unit and is ideal for individual rooms in homes and small offices. A **Cassette AC** is designed for larger commercial spaces with false ceilings. Its indoor unit is installed flush with the ceiling, providing a wider, more even air distribution from the center of the room, making it both aesthetically pleasing and highly effective for open-plan offices or retail showrooms.

The timeline for a commercial installation varies based on the project's scale and complexity. A single unit installation in an office might take a day, while a multi-unit VRF system for an entire building could take several weeks. We provide a detailed project timeline with every proposal after our initial site assessment.

An Inverter AC has a variable-speed compressor that adjusts its power based on the room's temperature, making it much more energy-efficient. While Inverter ACs have a higher initial cost, they save you significant money on your electricity bills, provide more consistent cooling, and are much quieter. For the climate in Mumbai, we highly recommend them.

Yes, all our repair work is backed by a service warranty. This provides you with assurance that the job is done right. The specific warranty period depends on the nature of the repair and any parts replaced, and will be clearly stated on your invoice.

Strange noises can indicate a variety of issues, from a loose part to a failing compressor. We recommend turning off the unit to prevent further damage and contacting us for a service visit. Our technicians can diagnose the source of the noise and perform the necessary repairs safely.

Absolutely. We specialize in creating customized Annual Maintenance Contracts (AMCs) for businesses with multiple locations, such as bank branches or retail chains. We can create a unified service agreement that covers all your sites, providing consistent maintenance standards and simplified billing.

We work with a wide range of industry-leading brands known for their reliability and performance in commercial applications. We are proficient in installing and servicing equipment from trusted names like Daikin, Mitsubishi Electric, Blue Star, O-General, and Samsung, among others. We can recommend the best brand and system to fit your specific requirements and budget.

We take compliance and safety as our highest priority. Our project managers are well-versed in the specific regulatory standards for various sectors, including healthcare air quality, fire safety (NOC requirements), and commercial building codes in the Mumbai region. Every project plan includes a detailed compliance check to ensure all work is performed to code and with the utmost safety.
