4 Warning Signs You Need To Replace Your Central Air Conditioner

With summer on the way and the weather beginning to warm, many Coloradans are starting to turn their air conditioning units on. 

While it’s not urgent to have a working air conditioner right now, the last thing you want is for your central air conditioner to stop working in the middle of July.

If you’re experiencing any of these signs, or if you think that it may be time to have your HVAC system maintained, call one of the experts at Guardian Heating & Air Conditioning.

Four Signs That You Need a New Central Air Conditioner

Old Age

The average life expectancy of an air conditioning unit is roughly 15 years, although the majority of older units tend to begin their decline around the age of 10.

Just like a car, the lifespan of an air conditioner will vary depending on the maintenance it’s received during its lifetime. 

Poorly maintained air conditioning units would probably begin to decline before the age of 10 significantly, but we’ve seen well-maintained air conditioners last for more than 15 years. 

Guardian Heating & Air Conditioning offers a preventative maintenance program that can save you a significant amount of money in the long-run, so don’t wait to get in touch with us to schedule an appointment!

Rising Energy Bills

One of the most common reasons that homeowners begin to think about replacing their central air conditioner is because they’re tired of paying more and more to heat and cool their homes.

Older air conditioning units are inefficient due to their designs, and poorly maintained contemporary units are likely to be running less efficiently than they should be. 

Ask your utility company to provide you with records of your energy bills, and look to see if you can spot a trend in the data.

If you find that your heating and cooling needs haven’t changed much, but your bills are increasing, then it’s probably time to think about purchasing a replacement unit.

While a replacement air conditioning unit can be initially expensive, you’ll enjoy better heating and cooling in addition to lower energy bills.

Expensive Repairs

Have you ever given up on a car because it needed repairs that cost more than the car was worth? Many homeowners find themselves in an identical position when it comes to their air conditioning unit. 

Even small repairs can add up over time, and an unreliable unit that continually requires the attention of an HVAC technician probably isn’t worth the financial hardship. 

If you’re curious about your current unit, you can always call Guardian Heating & Air Conditioning for an inspection.

Our HVAC technicians can inspect every element of your existing unit.

R 22 Freon

To become more eco-friendly, the United States is phasing out products that utilize R 22 Freon.

This chemical found in much older residential and commercial HVAC units.

While air conditioning units that use R 22 Freon are not banned, the cost of the chemical is quickly rising. 

If your current unit depends on Freon to run, you may want to consider switching to a unit that utilizes R410A, the more environmentally friendly cooling alternative.

In addition to helping the environment, you’ll likely see a boost in efficiency and lower energy bills.

At Guardian Heating & Air Conditioning, we understand that it can be expensive to replace an air conditioning unit, so we offer several financing options that can make your next HVAC repair or installation even more affordable. Give us a call at (303) 952-9047 to get your issues solved today.
