7 Signs of Heating & Cooling System Failure


Do you know some of the most common signs of impending heating or cooling system failure?

Homeowners really ought to be aware that the following seven symptoms can lead to water damage, deadly carbon monoxide leaks, a loss of heat or air conditioning on the most uncomfortable days, and increased expenses, just to name a few.

If your home comfort system is exhibiting one or more of the following symptoms, it may be time to choose Sanford.


Sign #1

If your system is more than 10 years old, then it may be time to consider replacement.

Today’s models are vastly more efficient than older models, which means that you’re likely paying far more than you need to in the form of higher energy bills and lower efficiency.

Sign #2 


Rust and metal fatigue are inevitable in older HVAC systems. Metal fatigue is caused by the stress of expanding and contracting metal as a system heats up and cools down over a period of years, which leads to breakdowns.

 Home comfort systems also manage humidity, which means that metal exposed to moisture eventually rusts. This can also lead to system failure.

Sign #3

A noisy system can be a sign of metal fatigue, which means that it’s nearing the end of its service life.

 Why wait until the hottest or coldest day of the year for it to fail, when you can avoid disaster and save hundreds or even thousands of dollars by using …

Sign #4


Rebates and incentives for energy efficient systems from energy providers and manufacturers can significantly reduce the cost of installation for homeowners.

 Act fast, because once the annual rebate pools are depleted, which is typically in late spring or early summer, you’ll have to wait until the rebate pools are replenished the following year.

Sign #5

Rooms that are too hot or too cold might not only be a sign of leaky ductwork, and airflow and pressure problems, but also an indication that a system is struggling to keep up with demands. It’s time to have your system look at by a professional if you’re experiencing this problem.

 It’s also useful to know that, on average, 30 cents of every $1 spent on heating and cooling a home disappears into thin air due to leaky ducts; duct leakage also heavily impacts hot and cold rooms.

Sign #6


Humidity problems such as condensation on windows, or overly dry air, can often be solved by newer systems that are specifically designed to address humidification and dehumidification!

 Many older systems just weren’t made with humidity challenges in mind. Moist areas can mean mold, mildew and bacteria, which leads to sickness and aggravated asthma and allergy symptoms.

Sign #7


Old refrigerant: If your air conditioner was manufactured before 2010, it probably uses an ozone-depleting refrigerant commonly referred to as R-22; many homeowners know R-22 as “freon.”

Federal regulations are phasing R-22 out, and only limited amounts are being produced to meet the needs of equipment manufactured before Dec. 31, 2009. This means that the cost of operation is going to continue to rise as supplies of R-22 dwindle.
