Should You Repair or Replace Your HVAC System?

Not every HVAC issue requires a new system. If your unit is newer, the repair is minor, and the system has been maintained, repair may be the smartest choice. Replacement may make more sense if your system is 10–15 years old, needs frequent repairs, struggles to cool the home, or uses excessive energy.

Fast & Reliable AC Repair Near You | Same-Day HVAC Service

  • How do you find a refrigerant leak in my AC system?
    We use pressure testing and electronic leak detection to pinpoint the exact source before any refrigerant is added. A recharge without finding the leak is only a temporary fix that leaves the underlying problem unsolved. Locating the leak first is the only way to give you a lasting repair.
  • Should I repair a refrigerant leak or replace my AC unit?
    It depends on your system's age, refrigerant type, and how severe the leak is. We give you a straight comparison of repair cost versus replacement cost so you can decide without pressure. If your system uses older R-22 refrigerant, replacement often makes more financial sense in the long run.
  • Who offers reliable AC repair services in Georgetown, TX?
    Roger Stuth Air Conditioning provides AC repair in Georgetown, TX, with a focus on accurate diagnosis and transparent recommendations before any work begins. We explain what we find and what it will cost so there are no surprises on your invoice.
  • What are the signs that my AC system has a refrigerant leak?
    Common signs include warm air blowing from the vents, ice forming on the refrigerant lines or indoor coil, a hissing or bubbling sound near the unit, and higher-than-normal electric bills. If you notice any of these, the system should be inspected before the problem worsens or causes compressor damage.
  • How long does an AC refrigerant leak repair typically take?
    Most refrigerant leak repairs are completed in a single visit once the leak location is confirmed. The total time depends on where the leak is and whether a component like a coil or valve needs to be replaced, but our goal is always to restore your cooling the same day.
  • Is it safe to keep running my air conditioner if it has a refrigerant leak?
    Running an AC with a known refrigerant leak puts the compressor at risk and can turn a moderate repair into a much more expensive one. It is best to shut the system down and schedule an inspection promptly. Catching a leak early almost always reduces the total cost of the repair.
  • What does AC repair in Georgetown, TX typically involve?
    A proper AC repair starts with a full system diagnosis to identify the root cause rather than just treating symptoms. That may include checking refrigerant levels, testing electrical components, inspecting the coil and drain line, and evaluating overall system performance before any parts are replaced.
  • Why does my air conditioner keep losing refrigerant after being recharged?
    If your AC repeatedly loses refrigerant, there is an active leak somewhere in the system that was never repaired. Recharging without fixing the leak is a temporary measure that lets the problem continue and can cause progressive damage to the compressor over time.
  • How do I know if my older AC system is worth repairing or if I should replace it?
    A good rule of thumb is to compare the repair cost against the remaining useful life and efficiency of the unit. We walk you through that comparison honestly, including how your refrigerant type factors in, so you can make a financially sound decision rather than one based on guesswork.
  • What type of refrigerant does my AC system use, and does it matter for repairs?
    It matters significantly. Older systems use R-22 refrigerant, which is no longer manufactured and now costs considerably more to source, making repairs on those units less cost-effective. Newer systems use R-410A or newer alternatives. Knowing your refrigerant type is an important part of any honest repair-versus-replace conversation.
  • Can a refrigerant leak cause my energy bills to go up in Georgetown, TX?
    Yes. When refrigerant is low, your AC has to run longer to reach the set temperature, which drives up electricity consumption. Georgetown summers put heavy demand on cooling systems, so even a small leak can noticeably increase your monthly utility costs if left unaddressed.
  • What should I look for when choosing an AC repair company in Georgetown, TX?
    Look for a company that diagnoses before it recommends, explains repair versus replacement honestly, and does not pressure you toward the most expensive option. Local experience with Georgetown's climate and a clear explanation of the work being done are strong indicators you are working with a trustworthy contractor.
