How Much Is a New Air Conditioning Unit?
In most homes across PA and DE, a new air conditioning unit falls in the $3,800 to $7,500 range. But that number can change depending on:
- The SEER rating: A higher Seasonal Energy Efficiency Ratio (SEER) means better efficiency, but it also means a higher upfront price tag.
- Your home’s size: Bigger spaces need more cooling power, which usually means a more powerful and more expensive system.
- How complex the installation is: If your AC is tough to access or your setup isn’t standard, installation may take more time and labor.
You might also run into extra costs for ductwork repairs, replacing an old thermostat, or upgrading to smart tech like a Nest thermostat.
How Do I Maintain My Air Conditioning System?
To keep your AC system running efficiently, start by changing the air filter every one to three months. This helps maintain airflow and reduces strain on your system. Once a year, clean the condenser and evaporator coils to prevent dirt buildup that can lower performance.
It’s also a good idea to schedule a professional tune-up before the cooling season begins. Len The Plumber offers thorough HVAC maintenance to help your system last longer and perform at its best.
Can My Air Conditioning Make Me Sick?
Your AC won’t make you sick on its own, but a poorly maintained system can circulate dust, mold, and allergens that trigger respiratory issues. Cold, dry air may also irritate your throat or sinuses, especially if you’re sensitive. Changing filters regularly and keeping humidity in check can reduce these risks and keep your air healthier.
How Long Do Air Conditioning Units Last?
Most air conditioning units last about 12 to 15 years with proper maintenance. If your system breaks down often, your energy bills keep climbing, or your home isn’t cooling evenly, it might be time for a replacement.
Regular care, like filter changes and yearly tune-ups, can help extend your system’s life and keep it running efficiently.
Why Is My Air Conditioning Unit Leaking Water?
A leaking AC unit usually means there’s a problem that needs attention. The most common causes are a clogged condensate drain line, frozen coils, or a dirty air filter, which can lead to water buildup.
Left unchecked, these leaks can cause water damage, mold, or even shut down your system. Sometimes, quick fixes like replacing the filter or clearing the drain line works, but a professional should check ongoing leaks.
If your AC leaks, a professional can diagnose the issue and help prevent further damage.
How Do You Repair an Air Conditioning Unit?
If your AC stops working, make a few simple checks: Ensure the thermostat is set correctly, the air filter isn’t clogged, and the system has power. Sometimes, these small issues are all it takes to get things running again.
For more serious problems like refrigerant leaks, electrical issues, or a broken capacitor, you’ll need professional help. These parts are complex and can be dangerous to fix on your own.
If your system still isn’t working after basic troubleshooting, it’s time to call a licensed HVAC technician.
What Is Ductless Air Conditioning?
Ductless air conditioning cools specific rooms without using ductwork. Each unit is mounted on a wall and connects to an outdoor compressor, giving you control over individual zones.
It’s a great option for homes without ducts or for cooling areas like additions or upper floors. These systems are energy-efficient, quiet, and easy to install, making them a flexible solution for targeted comfort.
How Does Central Air Conditioning Work?
Central air conditioning cools your entire home using a system of key parts: the condenser outside, the evaporator coil inside, an air handler or furnace blower, and a duct system that moves air throughout the house.
It uses refrigerant to absorb heat from inside your home and release it outside. As warm air passes over the evaporator coil, the refrigerant pulls the heat out, and cool air is pushed back through your ducts.
The system runs automatically based on your thermostat settings, making it efficient for keeping every room comfortable.
What Is a Mini-Split Air Conditioning Unit?
A mini-split AC unit is a type of ductless system that cools individual rooms instead of the whole home. Unlike traditional systems that rely on ductwork, mini-splits use indoor wall-mounted units connected to an outdoor compressor by refrigerant lines.
Mini-splits are a great fit for spaces like room additions, garages, or areas where zoned cooling is desired. They’re energy-efficient, easy to install, and allow you to control temperatures room by room.
Can a Nest Thermostat Replace Heating and Air Conditioning Controls?
A Nest thermostat can replace most heating and air conditioning controls, but it depends on your HVAC system’s wiring. It’s compatible with many setups, but older systems or dual-fuel units may need extra steps or a professional assessment.
Nest thermostats offer innovative features like learning your schedule, remote access from your phone, and energy-saving settings that adjust automatically. For homes with more complex systems, having a professional handle the installation is best to ensure everything runs smoothly.
How Do I Charge My Home Air Conditioning System?
Charging an air conditioning system means adding refrigerant, which you should not do on your own. Because of strict environmental and safety regulations, only EPA-certified technicians can handle refrigerants.
If your system is low, you might notice signs like warm air from the vents, hissing noises near the unit, or ice forming on the coils. These are clear signals to call a professional.
DIY charging can damage your system and violate federal laws. If your AC needs refrigerant, let a licensed technician handle it safely and correctly.
Does Air Conditioning Reduce Humidity?
Air conditioning systems naturally remove humidity as they cool your home. As warm air passes over the evaporator coil, moisture condenses and drains away, helping lower indoor humidity levels.
However, your system needs to be properly sized for this to work well. An oversized AC may cool the space too quickly without removing enough moisture. In areas with high humidity, it may be worth adding a whole-house dehumidifier for better control and comfort.
How Do I Clean My Air Conditioning Coils?
Before cleaning your air conditioning coils, always turn off the system’s power. To gently remove dirt and debris from the evaporator coil (inside) and the condenser coil (outside), you can use a soft coil brush or a commercial coil cleaner.
Cleaning the coils yearly helps your system run more efficiently and prevents unnecessary strain.
How Much Does Air Conditioning Cost in Electricity?
The cost of running your air conditioning depends on several key factors, including your system’s SEER rating, how often you use it, and local electricity rates. Operating a central air system costs between $0.06 and $0.88 per hour.
High-efficiency units use less power, and smart habits can help lower your bill. For example, using a smart thermostat, running ceiling fans, and keeping up with regular HVAC maintenance all make a difference.
