Having a new AC system installed should improve your comfort right away. It’s meant to cool your home evenly, run quietly, and help keep energy costs manageable. But that’s not always the case—especially if something wasn’t handled the right way during installation or if there’s a hidden issue. In homes around Minnetonka, problems with new AC systems can surface during the peak of summer when performance matters most.
Some signs show up quickly. Others are harder to catch until they start disrupting your daily routine. Whether it’s uneven temperatures in different rooms or the unit running way more often than expected, these early warning signs can point to a bigger problem that requires a closer look. Paying attention early can prevent long-term damage or inefficiencies.
Signs of Uneven Cooling
If your new AC installation in Minnetonka leaves you sweating in one room and freezing in the next, that's often not a problem to ignore. Uneven cooling can be frustrating, and it typically means something's not working the way it should.
When an AC is correctly sized and properly installed, it should deliver consistent cooling throughout your home. If one or more rooms feel warmer than others, this could be a sign of:
- Improper refrigerant charge
- Poor duct design or disconnected ducts
- Air leaks in the ductwork or walls
- Incorrect thermostat placement
- A system that's too small or too large for the home
For example, if the upstairs bedrooms stay hot while the downstairs living room feels like a fridge, the system may be unbalanced or the ductwork may be restricting airflow. Instead of constantly lowering the thermostat and overusing the AC, the better choice is to have it looked at by our technicians. They can identify where airflow is being lost and recommend adjustments or repairs that get the system functioning evenly across every room.
Unusual Noises During Operation
Your AC should run quietly in the background. Strange sounds are often one of the first signs that something’s off. A new system that starts making noises shortly after installation could mean parts weren’t tightened properly, components are rubbing against each other, or something more complex is going on inside.
Watch out for:
- Clanking or banging – often linked to loose parts or fan blades hitting other components
- Hissing – could mean a refrigerant leak or air escaping from duct connections
- Buzzing – electrical issues, debris in the unit, or a failing motor
- Clicking – possibly a control problem, like a faulty relay or a failing capacitor
If you just had an AC installed and any of these sounds become frequent, don’t ignore them. Equipment like compressors and fans can wear out quickly if they're under stress. Our professionals will inspect those sounds, trace them to their source, and prevent further damage from happening.
Frequent Cycling On and Off
Air conditioners are designed to cycle at regular intervals to keep indoor temperatures steady while using energy efficiently. If your new AC turns off and on constantly throughout the day, there's an issue that needs attention.
Frequent cycling—also called short cycling—adds unnecessary wear and can drive up energy bills. It also leaves your home less comfortable, as short bursts of cooling don’t allow the system to properly manage humidity.
Some common causes of short cycling include:
1. An oversized system that cools too quickly and shuts off before running a full cycle
2. A thermostat placed in a drafty or warm spot, causing false readings
3. Dirty or clogged air filters that disrupt airflow
4. Refrigerant problems or faulty control boards
Letting your AC continue to run this way won’t fix the problem. If you notice quick on-off patterns, this is the time to bring in our technicians who can check for installation flaws or settings that may be incorrect. Addressing this early helps the system work smoothly and last longer.
High Energy Bills After AC Installation
A brand-new AC system should help control your energy costs, not drive them higher. If your electric bill seems to spike shortly after installation—even though your usage habits haven’t changed—that’s a red flag something might be off.
Poor installation is one possible cause. If the unit was not correctly connected to existing ductwork, or if it’s the wrong size for your Minnetonka home, the system may be working harder than it should just to maintain indoor comfort. An improperly sealed system can also result in energy loss, especially if cooled air escapes before it reaches your rooms. As the unit struggles to cool your home, it consumes more energy and shortens the equipment’s lifespan.
Thermostat calibration can also impact energy costs. If it's reading incorrectly, the system may run longer or more often than necessary. Something as simple as incorrect pressure in the refrigerant lines or a poorly placed sensor can throw everything off.
Before digging into changes around your home, pay attention to when the spikes started. If energy bills jumped right after AC installation, have the system checked to see if adjustments or fixes are needed. A proper inspection can pinpoint whether the increase comes from operational issues, system sizing, or hidden inefficiencies.
Poor Airflow From Vents
If the air coming from your vents feels weak, inconsistent, or nonexistent in spots, your AC system’s performance is being held back. It’s a common issue that shouldn’t happen with a new installation. Poor airflow can make rooms feel warmer, humidity harder to manage, and force the system to run longer to reach set temperatures.
Here are a few causes to consider:
- Blocked or leaky ducts that restrict air delivery
- A damaged blower motor not pushing enough air
- Incorrect fan speed settings during installation
- Dirty air filters from construction debris
- Improperly sized ductwork that doesn't match the new unit
Take note of which rooms feel sluggish or under-cooled. If only one or two areas are affected, there may be a problem in that section of ductwork. But if the whole home feels like air is struggling to circulate, the problem could lie with the installation of the blower or a mismatch in airflow settings.
In one Minnetonka home, a family noticed their upstairs vent airflow had dropped significantly just days after installation. It turned out the return air duct was partially blocked, likely overlooked during the install. After clearing the obstruction and sealing some connections, temperatures normalized, and the house cooled evenly.
Don’t ignore airflow problems. Minor issues can restrict cooling performance and push your AC system harder than designed. Prompt troubleshooting helps extend the equipment’s life and restores consistent comfort.
Ensuring Longevity and Efficiency of Your AC System in Minnetonka
New air conditioning systems are a major investment for any homeowner, and the last thing you want after installation is a string of unexpected problems. Many issues faced in the first few weeks—like odd noises, blocked airflow, or abnormal energy use—can often be tied back to installation details or setup errors. They may seem small, but over time, they take a toll on comfort, efficiency, and long-term system health.
Taking quick action when things feel off is key. Whether a certain room never cools properly or your unit seems to be running nonstop, it’s better to get those early signs checked out before they create more problems. Ignoring them could mean higher energy costs or system damage that could’ve been prevented.
The earlier these issues are addressed, the less likely they’ll turn into larger repairs or require complete system adjustments. Staying proactive about your AC’s performance after installation helps it run more efficiently and keeps your home consistently comfortable during the hottest Minnetonka summers.
