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.

Can Two-Stage Cooling Benefit Your Home?

Can Two-Stage Cooling Benefit Your Home?An innovative upgrade for central cooling systems that works well in our region is two-stage cooling. Such a system contains technology that tells the compressor how fast to run based on the amount of cooling needed. Most of the time it will run at its slower speed. A single-stage system only runs at high speed, which creates some issues with energy consumption, indoor comfort, and the long term performance of the equipment.

Energy Savings

The compressor for an air conditioner changes the pressure of the refrigerant that removes the heat from the air. It’s the hardest working, moving part inside cooling systems and it works more efficiently when it can run more slowly for a longer period.

The compressor consumes the most electricity when it first starts up, which is also when most of the wear occurs. A system that runs for longer periods in slower cycles doesn’t start and stop frequently, and consequently lasts longer and uses less electricity.

Increased Comfort

Since the air handler for a two-stage cooling system continues to move air until the compressor shuts off, rooms further from the air handler receive more cooled air, helping them reach and maintain cooler temperatures. Increased running time also improves the air quality, since more air goes through the air filter. Two-stage systems run more quietly inside and out, an important consideration if the air handler or condenser sits close to bedroom or living areas.

Two-stage systems remove excess humidity, an important benefit of air conditioning. Not only does excess humidity make you feel warmer, it can harm your home and your health. A system that runs slower for longer periods will have time to condense more water vapor without having to turn the temperature down as you would with a single-speed system. Lower humidity levels in the summer improve air quality by reducing the dust mite population and lowering mold growth.

Although a two-stage cooling system will cost more initially, it will pay for itself in energy savings and greater indoor comfort. To learn more, contact Roth Heating & Cooling, providing HVAC services for Portland-area homeowners.
