Why Refrigerant Recharge is Crucial for Your Heat Pump

Refrigerant gas is the vital fluid of your heat pump, allowing heat transfer to heat or cool your space. A loss of this gas, often due to a microscopic leak, leads to a significant drop in efficiency, or even a complete breakdown. You will notice insufficient temperatures, noisier operation, and increased energy consumption.

At Thermopompe Montréal, we understand that gas recharge is not simply adding fluid. It is a technical process that begins with precise leak detection. We use advanced electronic equipment to locate the source of the leak. If a leak is found, we repair it according to industry standards before proceeding with the recharge. This ensures the durability of the solution.

Do not neglect the signs of a low gas charge. An undercharged heat pump works harder, wears out prematurely, and consumes more energy. Trust Thermopompe Montréal for a precise gas recharge, using the correct type of refrigerant, and preceded by a rigorous check to avoid repeated recharges.

⏱️

Longer Heating/Cooling Time

It takes much longer to reach the desired temperature, a sign of reduced efficiency.

Frequently Asked Questions about Gas Recharge

Is gas recharge included in maintenance?

No. Gas recharge is a repair performed when a leak is detected. Preventive maintenance includes checking the charge, but not the recharge itself.

Can you just recharge without looking for the leak?

No, that is contrary to good practice and potentially illegal. A recharge without leak repair is temporary and harmful to the environment. We always diagnose the cause.

How long does a gas recharge take?

A complete intervention (test, repair if necessary, recharge) generally takes 1 to 2 hours, depending on the complexity and location of the leak.

Do you use the correct type of gas for my heat pump?

Yes. We use the type of refrigerant specified by your unit's manufacturer. This is crucial for performance and safety.

Do you offer a warranty on the recharge?

Yes, we offer a warranty on the leak repairs performed. The recharge itself is guaranteed as long as the repaired leak does not reappear.

My heat pump is 15 years old. Is it worth recharging the gas?

It depends on the overall condition of the heat pump. We can assess the entire system during the intervention and advise you if a repair or replacement is more appropriate.

Is Your Heat Pump Losing Efficiency?
