Warning Signs Your A/C System is Dying

Vapor 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 Home & Cooling. We’ve helped Lake Oswego homeowners with HVAC decisions since 1976.
