5 Signs That a Residential Air Conditioner in Toledo OH Has a Refrigerant Leak

If a home air conditioner in Toledo OH isn’t doing its job, it could mean that it isn’t the right size. However, if the unit has been installed for a while and has recently started to exhibit symptoms, it could be due to low refrigerant levels. In most cases, topping it off isn’t a job for the do-it-yourselfer. Below are five signs that it’s time to call a professional for a refrigerant refill.

Inadequate Cooling

The home may feel cooler inside than out unless the unit has failed completely. However, if the homeowner can turn the thermostat down with no appreciable change in indoor temperature, the system may be low on refrigerant. While an older unit may struggle to keep up during the hottest part of summer, lackluster performance on an ordinary day may signal the need for a checkup.

Hissing and Gurgling Noises

Odd noises can indicate a variety of problems. In combination with uncomfortable temperatures, though, they could signal a refrigerant leak. HVAC refrigerant systems are permanently sealed, and leaks shouldn’t occur. Not every leak makes noise, but the homeowner should call a pro if they hear anything unusual.

Higher Utility Bills

If the user turns the thermostat lower to cool the home faster, a higher utility bill will be the only result. An Air Conditioner in Toledo OH that’s low on coolant can use a substantial amount of power, ruining its efficiency. If cooling bills are higher than average, or if there are usage spikes during the hottest days of the year, the unit may need more refrigerant.

Ice on Refrigerant Lines

Some homeowners may take ice on the lines as a sign that the unit is cooling, but there’s usually a problem. When the refrigerant level is low, the unit’s evaporator coil gets progressively colder because little indoor heat is being absorbed. If there’s ice on the unit’s refrigerant line, turn it off as quickly as possible and call an HVAC repair company.


When a system is low on refrigerant, it’s a sure sign of a leak. As mentioned earlier, home HVAC units are sealed systems, and leaks are the only reason refrigerant can escape. These leaks are serious because the coolant can be unsafe to handle. Homeowners should visit website domain for leak detection, service, and repair.
