HVAC & AC Service Frequently Asked Questions
Find expert answers regarding AC repair costs in Pune, chiller overhaul protocols, gas charging standards, and 24/7 emergency dispatch SLAs.
❓ How do I calculate what tonnage AC is needed for my room or factory? +
You can use our online Room AC Tonnage Sizer calculator right on this website! In general, for Pune climate: 100-120 sq.ft requires 1.0 Ton; 130-180 sq.ft requires 1.5 Ton; and 190-250 sq.ft requires 2.0 Ton (with additional adjustments for top floor sun exposure).
❓ What warranty is provided on spare parts and chemical servicing? +
All jet chemical cleaning carries a 30-day performance warranty. Inverter PCB soldering comes with a 90-day component guarantee. Gas recharging with brazing repair carries a 90-day leak-free guarantee, and new compressors carry manufacturer warranty up to 1 year.
❓ How quickly can your industrial breakdown crew arrive at Chakan or Ranjangaon MIDC? +
Our standby industrial mobile vans are stationed directly near Shikrapur and Chakan junction. For mission-critical factory breakdowns, our guaranteed arrival SLA is sub-45 minutes.
❓ Why is deep vacuum evacuation (<500 microns) required before gas charging? +
Modern refrigerants like R-32 and R-410A use synthetic Polyolester (POE) oil which is extremely hygroscopic (absorbs moisture from air). Moisture mixes with refrigerant to create hydrofluoric acid that eats compressor motor insulation. Pulling vacuum below 500 microns boils away all moisture and non-condensables.
❓ Can you repair Inverter AC PCB boards instead of replacing them? +
Yes! We run a dedicated micro-soldering electronics laboratory in Pune where we test, repair, and reprogram IPM modules, bridge rectifiers, and microcontrollers for Inverter ACs, commercial chillers, and refrigerators, saving customers up to 70% compared to new board replacement.
❓ What refrigerants and AC brands do you service? +
We service all major brands including Daikin, Voltas, Blue Star, LG, Carrier, Hitachi, Panasonic, Samsung, Godrej, Mitsubishi, and Carrier Transicold using genuine pure virgin R-32, R-410A, R-134a, R-404A, and R-407C refrigerants.
❓ Do you offer Annual Maintenance Contracts (AMC) for factories & clinics? +
Yes, Prime Cool offers comprehensive and non-comprehensive tiered AMCs tailored for residential homes, commercial office towers/clinics, and heavy MIDC industrial manufacturing plants with guaranteed uptime and standby technicians.
❓ What areas in Pune do you provide emergency HVAC & AC repairs? +
We provide 24×7 rapid emergency response across Wagholi, Hadapsar, Kharadi, Koregaon Bhima, Shikrapur, Shirur, Sanaswadi, Karegaon MIDC, Ranjangaon MIDC, Chakan MIDC, Bhosari, and all major Pune industrial zones with an SLA response under 45 minutes.
