Warning Signs Your A/C System is Dying

Warning Signs Your A/C System is DyingVapor compression, electrical, water drainage, computer technology and air quality — your air conditioner utilizes and links together an array of mechanics and properties to cool your home. As an A/C system ages or if it isn’t well maintained, a lot can go wrong. Following are warning signs that indicate your A/C unit is experiencing problems or dying.

Strange Noises

With a compressor, blower motor and airflow, air conditioners make noise — some more than others. If you hear any of these unusual noises, your A/C system needs immediate attention:

  • Droning: Laborious droning and whirring noises from your outdoor unit indicate significant compressor problems.
  • Grinding: Grinding and screeching noises from the indoor air handler or outdoor unit are telltale signs of a failing blower motor.
  • Clicking: If your A/C system won’t turn on and makes a rapid clicking noise, you have electrical problems to contend with.
  • Duct noises: Rattling, clamoring, whooshing and even banging noises from the air vents are usually caused by problems with ductwork design. Take care of duct problems before they affect your A/C system.

Too Many Repairs

When you’re uncomfortable, there’s no such thing as a small A/C repair. However, if your A/C has needed frequent repairs in recent years, you may be better off upgrading to a new A/C unit with a warranty. Talk to your A/C technician about lifetime costs of different A/C models. The lifetime cost is your estimated investment for the A/C purchase, installation, energy usage and maintenance from day one to the end of its useful service life.

Poor Performance, High Energy Bills

With so many interlinking systems, one unresolved A/C problem often causes another… and another. For example, an old compressor may cause ice to accumulate on the evaporator. Leaky air ducts make your A/C work harder. In both instances, your home comfort suffers, energy bills increase and other A/C parts may begin to fail.

Sooner or later, you’ll need to replace your A/C system. Start planning your new system by working with reputable HVAC professionals at Roth Heating & Cooling. We’ve helped Lake Oswego homeowners with HVAC decisions since 1976.

Our goal is to help educate our customers in the Metro Portland, Oregon area about energy and home comfort issues (specific to HVAC systems).

Condensation On My Air Conditioner Unit: Should I Be Worried?

Condensation On My Air Conditioner Unit: Should I Be Worried?When something is wrong with your air conditioner, it will let you know in a number of different ways. Maybe you have a gut feeling your energy bills are too high, and you certainly know when your home is uncomfortable. Another sign your air conditioner is failing is condensation collecting on and/or around it. Switch the thermostat and your panic buttons off, and keep reading before you make your next call.

What Harm is a Little Water?

Water condensation on your air conditioner’s evaporator coil is normal. However, as you’ve realized, water leaking from your air conditioner onto your floor is not acceptable. Depending on where your indoor A/C unit is located, condensate leaks may cause damage to your ceiling, walls, flooring and/or other building materials and property.

What to Do?

In order to know what to do about a leaky A/C, it’s helpful to know how condensation forms and the most common reasons why it’s leaking. Condensation forms as a result of water vapor in warm airflow being pulled across the cold evaporator coil. Under normal conditions, the condensate drips into a pan, flows down the drain and through a tube away from your home. End of story — unless your A/C unit is experiencing these problems:

  • A blockage in the drain tube is causing an overflow. Your HVAC technician uses either a powerful blower or heavy-duty vacuum to push or pull the blockage through. Then, the line is chemically treated.
  • The float switch has malfunctioned. Some air conditioners have a float switch that turns off the unit when water fills the drip pan too high. If your A/C is equipped with such a device, but it’s not working, it needs to be repaired or replaced.
  • The drip pan has rusted through or it has broken. Your technician can simply replace the drip pan.

Ask your HVAC technician or plumber if your A/C has a float switch. If not, you’d be wise to have one installed in the drain trap. For assistance repairing air conditioner condensation problems in your Portland home, please contact the professionals at Roth Heating & Cooling today.
