Top 6 Signs It’s Time for an Air Conditioning System Replacement
Proper air conditioner maintenance can greatly extend the lifespan and efficiency of your AC system. But every AC unit will eventually need to be replaced. Here are six warning signs that it’s time to replace your air conditioning system.
1. Making Frequent Repairs
Does it feel like you have your AC technician on speed dial? Frequent air conditioning repairs can start adding up and you can ultimately pay more for repairs than a new unit. If you’re paying half the cost of a new unit just to repair your current one, it’s time to replace it.
2. You Smell Strange Odors
An air conditioner should be felt, not smelled. If your nose is picking up on any musty or molding scents from your vents, it’s time to call a HVAC technician. It could be an easy repair, but it might require an AC unit replacement.
3. AC System Does Not Cool Your Home Properly
If certain rooms are cooler in comparison to others in your home, this is a sign your air conditioning system is not working effectively and needs to be replaced. Our expert HVAC technicians will help you find a new air conditioning system to ensure each room in your living space is comfortable throughout the summer season.
4. You Hear Strange Noises
Banging, rattling, squealing, and grinding noises should not be coming from your AC unit. However, sometimes dust and debris can block the flow of air, or a compressor could be faulty. If your unit is approaching the end of its lifespan, repairs might not be so simple and replacing your air conditioning system might be the way to go.
5. AC System Requires Freon
Air conditioning units manufactured before 2010 use R-22 refrigerant, also known as Freon, to cool the air inside the unit. This gas contains ozone-depleting agents that are harmful to the environment. If your AC unit uses Freon, it’s a good idea to replace it with a newer AC model that uses eco-friendly refrigerants.
6. High Energy Bills
You should have a pretty good idea of what a normal energy bill is for your home. When your bill skyrockets, an inefficient AC unit could be the problem. If you have an older unit, the best way to solve this problem is to replace it.
4 Benefits of Installing a New Air Conditioner
When you choose to replace your air conditioner, you get the benefits that come with a new model. A new air conditioner isn’t just a replacement, it’s a noticeable upgrade in how your home feels every day. With modern air conditioner installation, you get better efficiency, cleaner air, and more consistent comfort without the constant stress of an older system struggling to keep up.
1. Higher Energy Efficiency
One of the main issues with an aging unit is a loss of energy efficiency. A new AC unit improves efficiency and brings down your energy bill.
2. Better Indoor Air Quality
Newer air conditioning models have advanced technology that improves indoor air quality. This helps with humidity and ventilation, and those pesky smells.
3. Long-Lasting Systems
An advantage of hiring a professional to perform an air conditioning replacement and installation includes investing in a reliable system. Modern, energy-efficient units are designed to last around 12 years. Paired with our industry-leading warranties, choosing to get an AC replacement is a responsible decision.
4. Improved Indoor Comfort
With a more efficient unit comes a more comfortable home. Your new AC unit can keep your home cooled evenly, so no more wildly varying temperatures throughout your home.
