Every design choice we make starts from humidity, not temperature. Anyone can push air. Pulling water out of it, cheaply and quietly, for fifteen years, is the actual job. We size equipment for the load you'll have in August, not the showroom brochure.
Most of our service calls come from systems someone else sold: 2-ton units in 3-ton rooms, ducts run through un-insulated attics, drain lines pitched wrong. We quote for the building, not the catalogue.
Coastal Kerala cooling load, April peak, 1.5-storey residence. Twice the Delhi winter equivalent.
Installations logged across the Aircon Group in Kerala since 1999. Five offices, fourteen-district footprint.
Air conditioning, at Modern Aircon, means sensible heat and latent humidity dealt with together. From a single bedroom split in Kaloor to a 200-ton variable refrigerant flow at Kakkanad, the design principle is the same: size it for August, commission it with a manometer, service it on a calendar.
↓ The gauge drops with the page. Keep reading.
Carrier, Daikin, LG, Midea, Godrej and Toshiba: authorised for all six. We quote from a load calculation, not a catalogue multiplier, and we tell you in writing which tonnage fits. If a 1.5-ton will hold, we will not sell you a 2-ton to pad the invoice.
Turnkey design and install: BOQ, drawings, commissioning reports, balancing. We've handled 160-key hotel retrofits alongside single-studio builds with the same named engineer. Expect CAD by day four; expect dust sheets on the furniture.
Roof-mount and front-mount bus AC for inter-state coach operators, school bus fleets and the Kerala State Road Transport Corporation. We install, we gas-top, we ground-the-chassis, and we train the operator's in-house mechanic to do the weekly filter wash.
Close-control units, in-row cooling, hot-aisle/cold-aisle containment, redundancy to N+1. 24°C ± 1°C, 50% RH ± 5%, logged to the ticketing system. Clients include Infopark tenants and the back-offices of three private banks.
Air-cooled scroll up to 100 TR, screw and centrifugal above that. Cooling towers, primary-secondary pumping, and the realism that pump heads routinely get value-engineered out. We tell you before we install what that compromise will cost you in year five.
Above zero, water stays liquid. The compressor pulls sensible heat out, the coil drains it away, the room sits at its set point. This is the job for nine-tenths of the buildings we walk into.
The temperature holds. Energy keeps going in, 334 kilojoules per kilogram,
and the column refuses to move. Water is turning into ice.
This is where air conditioning ends and refrigeration begins.
Under the freezing line, every job is a promise against spoilage. A seafood processor losing an hour of refrigeration loses a tonne. Our reefer trucks, cold rooms and blast freezers are sized for what happens when the power cuts at 2 a.m. and the generator takes forty seconds to come up.
PUF-panel walk-ins, 40mm to 150mm thickness, built on site. For florists, fish markets, supermarkets and the back room of the hotel kitchen. Condensing unit outdoor, evaporator inside, separate lock, daily defrost timer, digital controller you can actually read.
Thermo King and Carrier Transicold installs, AMC, and round-the-clock roadside response along NH 66. Dairy from Idukki, prawns from Kollam, pharma to Bengaluru: the trucks we fit keep their set point through the ghat sections, or we hear about it on the phone before dawn.
Temperature-mapped cold stores, 21 CFR Part 11 compatible data loggers, backup compressors with auto-switchover, and the paper trail to satisfy a CDSCO inspector. We write the SOPs; we also show up for the audit.
Plate freezers, IQF tunnels and −40°C blast chambers for the Kollam and Alapuzha seafood processors. Ammonia and R-404A systems, built for the August landing when the trawler backlog has to freeze in four hours or it goes to waste. We've been commissioning these since 2011.
Load calculation from first principles, not a rule-of-thumb multiplier. We photograph the ceiling void, the electrical panel, the condenser sightlines. Report in your inbox within 72 hours.
Capex, opex, noise figures and warranty matrix in a single PDF. We tell you which option we'd put in our own house, and why. Revisions free until signed.
Drawings stamped, copper brazed, vacuum pulled to 500 microns, refrigerant weighed in. Photograph every braze joint before insulation. We leave the site tidier than we found it.
Temperature + RH logged over 48 hours, balanced airflow per grille, labelled isolators. Then the first AMC visit lands on your calendar three months out. Automatically.
"Modern Aircon was the only contractor who asked to see the attic before they quoted. That told me everything I needed to know."
