What homeowners should know
Refrigerant does not normally get used up like fuel. Low charge can indicate leakage or another service issue that requires proper measurements and repair planning.
What homeowners should and should not do
- Turn cooling off if the coil is frozen
- Do not add sealants or refrigerant yourself
- Note hissing or recurring icing
- Ask how a suspected leak was confirmed
Refrigerant Is Not Consumed
A sealed system does not use refrigerant the way an engine uses oil. If the charge is low, it left through a leak. That is why simply adding refrigerant is a temporary measure at best: without locating and repairing the leak, the same problem returns, usually sooner the second time. Ask any provider how the leak was located before agreeing to a recharge.
Why This Work Requires a Qualified Technician
Refrigerant handling is regulated, requires certification and specialized equipment, and involves pressures that are genuinely dangerous to work with untrained. Aerosol sealants sold for the purpose can contaminate a system and complicate later repairs. This is one area where homeowner intervention almost always costs more in the end.
Service process
How a suspected leak is confirmed
Procedures vary by provider and system. A typical residential visit may include these steps:
- 1Confirm the reported symptoms and thermostat settings
- 2Inspect accessible airflow and filter conditions
- 3Evaluate indoor and outdoor equipment operation
- 4Take relevant electrical, temperature or pressure measurements when appropriate
- 5Explain likely causes and discuss options before work proceeds
Denton's long warm season keeps home cooling systems working hard for months at a time. Heat makes symptoms easier to notice, but the underlying cause still needs a system-specific evaluation.
Homeowner questions
Frequently asked questions
What are the signs of low refrigerant?
Reduced cooling, longer run times, ice on the line set or indoor coil, and sometimes a hissing sound. None of these confirm a leak on their own — measurement does.
Is a leak repair worth it on an older system?
It depends on where the leak is, the refrigerant type and the condition of the rest of the system. A coil leak on an aging unit is one of the situations where comparing replacement makes sense.
What should I have ready when I call?
Your five-digit ZIP code, a short description of the symptom, when it started, the approximate age of the system if you know it, and anything you have noticed such as ice, water, odors or thermostat messages.
Is this website the contractor who performs the work?
No. This is a free connection service for homeowners. Participating contractors are independent businesses responsible for their own work, pricing, licensing and insurance, and you authorize any work directly with them.
