In Lahore, a UPS is not a luxury it is how the house keeps running during load shedding. When your UPS stops giving backup, charges slowly, or shuts off under load, the problem is almost never just the battery. GharFix technicians diagnose the full system battery condition, charger circuit, and inverter board before recommending any repair or replacement. All major brands serviced. Same-day slots across DHA, Bahria Town, Gulberg, Johar Town, and all major Lahore areas.

Battery testing, old battery removal, and new battery installation for all UPS brands. Lahore’s long and frequent load shedding cycles discharge batteries deeper than they were designed for most batteries in Lahore homes fail after 2 to 3 years rather than the rated 4 to 5. We test before recommending replacement, not by default.
The inverter board converts stored DC battery power to AC output when it fails, the UPS gives no backup even with a fully charged battery. Voltage spikes during LESCO load restoration are the leading cause of inverter board damage in Lahore. Component-level repair where possible full board replacement when the damage is beyond repair.
A UPS that runs on mains but never charges the battery has a failed charging circuit not necessarily a dead battery. Many Lahore homeowners replace the battery when the actual fault is the charger, spending double unnecessarily. Our technician tests both before any part is ordered or replaced.
Homage and Tesla inverters are among the most widely installed home backup systems across Lahore. Both use proprietary inverter boards that require brand-specific diagnostic knowledge. GharFix technicians are trained on both fault diagnosis, component repair, and battery replacement for all current models.
AGS and Osaka are the dominant UPS battery brands in Lahore’s residential market. We supply and install both with load testing before installation to confirm the new battery is correctly matched to your UPS unit’s charging and discharge specifications.
UPS repair and maintenance for offices, shops, and commercial setups including rack-mounted and online UPS systems used for servers and sensitive equipment. Commercial UPS faults are quoted after on-site assessment same-day emergency response available for business-critical systems.
New UPS or inverter setup unit placement, battery connection, load calculation, and circuit integration with your home DB. Correct load sizing is critical an undersized UPS that cannot handle your actual load will trip or fail within months in Lahore’s heavy usage conditions.
Upgrading from a single-battery to a multi-battery setup, or replacing an underpowered unit with one rated for your actual load. Common when a home adds an AC, a new floor, or additional appliances that the original UPS was not sized to support. Load assessment done before recommending a new capacity.
A UPS that trips under load or runs hot has either been given more load than it can handle or has internal components transistors, capacitors, or cooling fans that have degraded. In Lahore’s heat, UPS units in enclosed spaces run hot year-round and fail faster than their rated lifespan.
UPS problems in Lahore follow a very specific pattern shaped by how often and how deeply the batteries are discharged during load shedding and how badly LESCO voltage spikes affect internal components. These are the faults our technicians see most often.
The most common UPS complaint across Lahore. Short backup time means the battery is no longer holding a full charge either through age-related capacity loss, deep discharge damage from extended outages, or a charging fault that never let the battery reach full charge. A battery load test takes 10 minutes and tells you definitively whether the battery needs replacement or the charger is the actual problem.
A constant beep from a UPS during load shedding almost always means overload the connected load exceeds the UPS’s rated output capacity. In Lahore homes, this happens when an AC, refrigerator, or water pump is accidentally left connected to the UPS circuit. Switch off heavy appliances first. If the beeping continues with only lights and fans connected, the fault is internal likely a failing inverter board or a battery below minimum discharge threshold.
If the UPS runs connected appliances from mains but the battery indicator never moves, the charging circuit has failed not the battery. This is one of the most misdiagnosed UPS problems in Lahore. Replacing the battery when the charger is faulty means the new battery also never charges. GharFix tests the charger output voltage before any battery is touched.
If your UPS clicks to battery even when LESCO power is on, it is detecting the incoming mains voltage as outside its acceptable input range a common result of Lahore’s voltage fluctuation. The UPS is protecting itself and your appliances correctly. The fix is either a stabilizer upstream of the UPS or adjusting the input voltage window setting if your UPS model supports it.
A UPS that powers on, shows a battery indicator, but gives no output to connected appliances has a failed inverter board the component that converts battery DC to AC output. This is distinct from a battery problem and is almost always caused by a voltage spike that burned an IGBT or MOSFET on the inverter board. Component-level repair is possible in most cases.
A battery overheating during charge means either the charger is pushing too high a charge current a charger circuit fault or the battery itself has an internal short causing it to absorb current it cannot store. A hot battery is a safety concern, not just a performance one. Switch the UPS to mains-only mode and call a technician before the next load shedding cycle.
GharFix technicians are trained on all major UPS and inverter brands sold in Lahore’s residential and commercial market. Whether your unit is a basic single-battery home UPS or a high-capacity multi-battery inverter setup, we carry the diagnostic tools and compatible components for your brand.
Do not see your brand? Call us — if it is sold in Lahore, we have almost certainly serviced it.

A UPS repair done without proper diagnosis either fixes the symptom while missing the cause or replaces a part that was not faulty to begin with. Here is how GharFix approaches it differently.
Every GharFix UPS diagnosis covers the battery condition, the charger circuit output, and the inverter board function tested separately. Replacing just the battery when the charger is faulty, or the inverter board is failing, means the problem returns within weeks. We find the actual fault before recommending any part.
UPS and inverter repair requires knowledge of both electronics and battery chemistry it is not a general electrician job. Every GharFix technician assigned to UPS work has passed a skills assessment specific to inverter systems before being deployed to any Lahore home.
After diagnosis, you receive a full cost breakdown battery replacement, charger repair, or board component work before anything is touched. You approve the quote. Work starts. No additions after the job is done.
Every UPS repair and battery installation comes with a 30-day service warranty. If the same fault returns within that period, we come back and resolve it no extra charge.
Call or WhatsApp with your UPS brand, model, and what it is doing or not doing. Same-day slots available across most Lahore areas.

UPS repair cost in Lahore depends on the fault. A charger circuit repair starts from PKR 500. Battery replacement is quoted based on battery brand, type, and capacity required for your UPS model. Inverter board component repair starts from PKR 1000 depending on the failed components. GharFix confirms the full cost after diagnosis before any work begins or any part is ordered.
If a new battery still gives no or very short backup, the charger circuit likely never charged the new battery correctly, or the inverter board has failed independently of the battery. This is one of the most common UPS mistakes in Lahore replacing the battery when the actual fault is elsewhere. A proper diagnosis tests all three components separately before any recommendation is made.
Standard UPS batteries are rated for 4 to 5 years under normal use. In Lahore, where load shedding causes deep and frequent discharge cycles — sometimes 8 to 12 hours daily in summer most batteries degrade to replacement level within 2 to 3 years. High-quality tubular batteries handle deep cycling better and last longer in Lahore's conditions compared to standard sealed lead-acid types.
Continuous beeping during load shedding almost always means overload the connected load exceeds the UPS's rated capacity. Turn off heavy appliances especially AC, water pump, iron, and refrigerator and the beeping should stop. If it continues with only lights and fans connected, there is an internal fault either a failing battery below its minimum threshold or an inverter board issue.
Yes. LESCO voltage spikes during load restoration are one of the most common causes of inverter board damage in Lahore homes. The UPS is designed to protect appliances from fluctuations but the board itself absorbs the spike in doing so. Repeated exposure to high-voltage restoration events, common in areas with unstable LESCO supply, degrades inverter board components over time.
For a standard Lahore home running lights, fans, a router, and a television during load shedding a 1,000 to 1,500VA UPS with a 150Ah battery is typically sufficient. If you need to run a small AC or water pump, capacity requirements increase significantly and a dedicated inverter system with multiple batteries is more appropriate. GharFix includes a load assessment as part of every new UPS installation.
