Weight-based R134a/R1234yf refill with UV leak detection and compressor oil — not a roadside pressure-based top-up. Vent temp verified < 10°C before handover.
Refrigerant is charged by weight, not by pressure gauge. Every system has a charge mass printed on the under-bonnet label — typically 450–650 g of R134a on Indian mass-market cars and 500–750 g of R1234yf on newer premium models — and the recovery machine is programmed to that figure to ±5 g. Topping up 'until the gauge looks right' is what leaves a car either undercharged (poor cooling, compressor starved of oil-carrying refrigerant) or overcharged (high head pressure, cut-outs in traffic, eventual compressor failure). A refill here is a recovery-vacuum-recharge cycle: the old charge is recovered and weighed to reveal how much actually leaked, the system is held under vacuum to confirm it holds, UV dye goes in with PAG or ND-8 oil to the correct spec, and vent temperature is verified below 10°C before the car leaves.
Why we're the right choice
- Exact-weight charge to manufacturer spec (±5g accuracy)
- UV dye leak detection — find and fix the leak first
- PAG compressor oil included in every refill
- R1234yf capability for BMW, Mercedes, Audi, Porsche, Volvo
- 1-year cooling performance warranty
Common problems we diagnose & fix
AC cools for a month, then goes warm again
- Likely cause: Slow leak, usually a condenser stone-chip or a shrunk O-ring, never diagnosed
- Our fix: Weigh the recovered charge, trace with UV dye, replace the leaking seal or condenser before recharging
- Urgency: Repair soon
Cools on the highway, warm in Hyderabad traffic
- Likely cause: Overcharge or a blocked condenser raising head pressure until the high-pressure switch cuts the clutch
- Our fix: Recover, weigh, recharge to label mass and clean the condenser face
- Urgency: Repair soon
Compressor cuts in and out every few seconds
- Likely cause: Undercharge — the low-pressure switch is short-cycling the clutch
- Our fix: Vacuum test for a leak, then charge to exact mass with oil correction
- Urgency: Fix immediately
New premium car refused a refill at a local shop
- Likely cause: Vehicle uses R1234yf, which needs different fittings and a dedicated machine
- Our fix: Charge on the R1234yf machine with HFO-compatible oil
- Urgency: Monitor
Metre Per Second vs authorised centre vs local garage
| Feature | Metre Per Second | Authorised centre | Local garage |
|---|---|---|---|
| Charge method | Recovery machine, programmed to the label mass, ±5 g accuracy | Recovery machine to label mass | Can top-up by gauge pressure — no weight control |
| Leak diagnosis | Recovered charge weighed to quantify the loss, UV dye added, system vacuum-held | Leak test performed, usually as a separate paid job | No leak test — car returns in six weeks |
| Refrigerant type | R134a and R1234yf both stocked, separate machines to avoid cross-contamination | Correct type for the brand | R134a only — R1234yf cars often refused or wrongly filled |
| Compressor oil | PAG or ND-8/HFO to the compressor's spec, dosed with the charge | Correct oil, billed separately | Often omitted — the compressor runs dry |
| Handover check | Vent temperature verified below 10°C, printout of charge mass | Vent temperature checked | 'Feels cold' at idle |
Our repair process
- Read the under-bonnet label for refrigerant type and exact charge mass
- Recover the existing charge and weigh it — the shortfall shows the leak rate
- Pull vacuum and hold to confirm the system is sealed
- Add UV dye and the compressor's specified PAG or ND-8/HFO oil
- Charge to the label mass on the programmed machine, ±5 g
- Run the system and check high and low side pressures against spec
- Verify centre-vent temperature below 10°C with a probe thermometer
- Issue the charge printout with the recorded mass

What customers say
“Best independent workshop in Hyderabad for complex repairs. They have factory diagnostic tools and actually know how to use them. Transparent pricing, 1 year warranty, free pickup. What more can you ask?”
Ashwin K. — Luxury Car, KPHB · ★★★★★ (Google)
“Diagnosed my transmission issue in 1 hour using factory tools. Another workshop had it for 3 days and couldn't find the fault. MPS is the real deal — specialists, not generalists.”

Frequently asked questions
How do I know if my car actually needs gas, or something else?
Weigh the recovered charge. If the system still holds near its label mass and cooling is poor, the fault is elsewhere — blocked condenser, failed blend-door actuator, weak compressor or a clogged cabin filter — and adding gas will not fix it. That is why we recover and weigh before selling anyone a refill.
How often should AC gas be refilled?
A sealed system should not need topping up at all. Losing charge in under two years means there is a leak. Anyone who tells you an annual 'gas top-up' is normal maintenance is selling you refrigerant to replace what is escaping through a fault they have not looked for.
My car takes R1234yf — is that really more expensive?
Yes, the refrigerant itself costs several times more than R134a and needs a dedicated machine and HFO-compatible oil, which is why the premium-car charge is ₹2,999 against ₹1,299. What you should not pay is the ₹8,000–₹14,000 dealers typically bill for the same amount of gas.
Can you fill AC gas at my home or office?
No — proper recovery, vacuum and weighed recharge need the machine on shop power, and a roadside pressure top-up is exactly the practice that damages compressors. Use the free pickup and drop instead; most AC recharges are done and the car returned the same day. Call 8555824915.
