A/C Not Working After Building System Outage? Here’s Why

A/C Not Working After Building System Outage? Here’s Why – And How ROMA Heating & Cooling Can Help in Metro Vancouver

Have you noticed your air conditioner suddenly stopped working properly after a building-wide cooling system shutdown or maintenance event? If your A/C was working perfectly, but now the metal cooling fins are only cold in one small area while the rest of the unit stays warm or dry, you’re likely dealing with a deeper issue — one that won’t fix itself.

At ROMA Heating & Cooling, we specialize in high-accuracy diagnostics and repair services for residential and multi-unit A/C systems, especially in condos, apartments, and high-rise buildings across Metro Vancouver. If your system started misbehaving after a building-wide HVAC outage, and you’ve recently had refrigerant added, your system might be suffering from low refrigerant, a leak, or system imbalance.

Real Case: A/C Not Cooling After Building Machine Failure

Let’s walk through the situation many of our clients have faced:

“My A/C worked perfectly before. Then the main cooling machine of the building went down, and ever since it came back on, my A/C hasn’t worked. Only a small part of the metal fins on the indoor unit is cold and wet. The rest is warm and dry. A repairman came on April 27th and said my unit lacked refrigerant, so he added some. But now it’s acting up again.”

Sound familiar?

You’re not alone. This type of problem is common in buildings with centralized HVAC infrastructure, especially in Metro Vancouver’s high-rise condos that use in-suite fan coil units connected to a central chiller or cooling tower.

Understanding the Problem: Why Your A/C Stopped Cooling Properly

Your air conditioning system relies on a closed refrigerant cycle to transfer heat out of your unit. When it’s not functioning correctly, several symptoms can occur, including:

• Partial cooling (only a small area of coil is cold)
• Warm airflow from the vents even when A/C is on
• Unit runs continuously without cooling the space
• Sudden rise in hydro bills
• Condensation or water leaks
• Strange noises or frequent cycling

If your cooling fins are only cold in a small area, that’s a classic sign of a refrigerant imbalance or insufficient refrigerant flow. And if refrigerant was added recently but symptoms have returned, there could be a refrigerant leak or improper system charge.

Why A/C Systems Fail After a Building Machine Shutdown

In buildings with central HVAC systems, individual units like yours rely on a shared infrastructure — a chiller, cooling tower, or boiler system. If the main machine goes down, it can impact refrigerant pressures, water flow, or control signals across all connected suites.

Here’s what might have happened in your case:

1. Pressure Loss or Imbalance

When the building system shut down, refrigerant pressures in the loop may have dropped. Upon restart, your unit could be misaligned with the system’s pressure levels, preventing proper heat exchange.

2. Undetected Refrigerant Leak

The refrigerant added during your April 27th repair may have leaked out again. Even small pinhole leaks can empty a system within weeks — especially if they weren’t pressure tested or properly sealed.

3. Compressor or Valve Strain

Temporary shutdowns can stress components like expansion valves, TXVs, or compressors, especially in aging or overworked systems.

4. Air or Moisture Contamination

If refrigerant was added without evacuating the system, air and moisture may be contaminating the refrigerant, reducing cooling performance and increasing internal corrosion.

How ROMA Heating & Cooling Diagnoses and Repairs A/C Issues Like Yours

At ROMA, we’ve helped hundreds of homeowners across Vancouver with A/C units that stopped working after building outages or previous service calls. Our process is designed to uncover the root issue on the first visit — not just apply temporary fixes.

Our Diagnostic Process Includes:

1. Full System Pressure Testing

We test both high and low-side refrigerant pressures to determine if the system is low on refrigerant or overcharged.

2. UV Dye or Electronic Leak Detection

We locate hidden refrigerant leaks in coil fins, valves, line sets, or connections — even in tight spaces.

3. Coil Surface and Temperature Analysis

We use infrared thermography to assess coil temperature distribution, pinpointing where refrigerant is flowing and where it’s restricted.

4. Refrigerant Recovery and Evacuation (if needed)

We remove contaminated refrigerant and use a vacuum pump to clean the system before recharging to manufacturer specs.

5. Electronic and Control System Check

We check all relays, thermostats, expansion valves, and control signals to ensure your unit is communicating properly with the building system.

What You Shouldn’t Do

If your system is showing partial cooling or refrigerant loss symptoms:

• Don’t keep running it — it could damage the compressor or burn out components
• Don’t top it up with more refrigerant without first identifying leaks
• Don’t reset or override the thermostat multiple times — this can confuse the logic board or control module
