5 Signs You Might Need Air Conditioning Replacement
Are you considering air conditioning replacement? If it’s more than 10 years old, there are many advantages to upgrading. Not only will a new unit be more efficient and powerful than its predecessor—it could also lower energy costs while ensuring that your home remains cool during the hot summer months. Here are five signs you may need to consider installing a new air conditioner:
- Age: If your air conditioner is more than 10 years old, it may be time to consider replacing the unit.
- Noises: Abnormal noises coming from the AC unit could indicate a problem. Your air conditioner should only make a low hum when it’s running. Grinding, squealing or buzzing sounds could be a sign that it’s time to replace the unit.
- Smells: If you start to notice strange smells coming from your AC unit, this could mean there is dust, mold or mildew buildup in the system. A bad odor could be a warning sign that your air conditioner needs to be replaced.
- Leaking water: If you notice fluid leaks around the unit, this could indicate a refrigerant leak.
- Uses R-22: If your home’s air conditioner uses R-22, a refrigerant also called Freon, which is no longer used, it may be time to replace it with a newer model.
What SEER Ratings Mean for Your Denver AC Installation
When you’re planning a new air conditioner installation in Denver, SEER rating is one of the most important factors to get right. SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an AC unit cools your home: the higher the number, the lower your energy bills. Choosing the right SEER rating is a key part of any smart AC installation, and it’s something our Denver technicians help you navigate every time.
Older air conditioners often run at a SEER of 12 or less and rely on R-22 refrigerant, which is no longer used. Today’s high-efficiency AC units carry a SEER of 13 to 21 and use eco-friendly refrigerants like R-410A. Upgrading to a high-SEER system during your installation doesn’t just cut cooling costs, it can also qualify you for major Xcel Energy rebates and tax credits. With a unit rated 15 SEER or higher, Denver homeowners may be eligible for substantial savings, and Lakeside is one of the top rebate-producing AC installers for Xcel. (Check with your tax professional to confirm your eligibility.)
But the right SEER rating only pays off when your air conditioner is sized correctly for your home, which is where professional AC installation in Denver makes all the difference. An oversized or undersized unit wastes energy and wears out faster, no matter how high the SEER. When sizing and installing your new system, our Denver AC installation team factors in:
- Denver’s high-altitude climate
- Size and layout of your home
- Your home’s windows & sun exposure
- Insulation levels
- Number of people who live in the home
- Your home’s existing ductwork
Get the SEER rating and sizing right together, and your new AC delivers peak performance and maximum savings for the entire life of the system.
