Carrier HVAC Repair

Whether it’s your central air conditioner, ductless mini-split, furnace or boiler, Sears Home Services will send a qualified HVAC repair service technician to your home to repair and maintain your Carrier appliances. We know the importance of keeping your HVAC system maintained and ready to use on a daily basis.

Sears Home Services has been working on Carrier systems for years. Our experienced HVAC techs know these systems inside and out.

Here a rundown of the common problems that our technicians face when repairing Carrier systems.

AC Not Cooling Right

Imagine yourself in the middle of summer and your house feels like an oven even with the AC running. We get these calls all day long when the temperature climbs.

The first thing to check is your air filter. Sounds too simple, but you wouldn't believe how many service calls come down to a clogged filter. When air can't flow through, the coil gets too cold and freezes up. Now you've got no cooling at all. Change those filters every month during the summer to keep your system running smoothly.

Refrigerant levels get low over time. Tiny leaks that are hard to spot let that coolant escape bit by bit. Your Carrier might run all day but never get the house comfortable. Low refrigerant also makes the compressor work too hard. It wears it out way faster than normal. Adding refrigerant isn't a DIY job these days. Techs need special licenses and equipment to handle it legally.

Schedule central air repair service whenever you notice diminished cooling and basic troubleshooting doesn’t fix the problem.

Outdoor Unit Problems

Condenser coils get filthy, especially if you've got cottonwood trees in your yard or lots of dust in your area. The outdoor unit can't dump heat properly when those coils get gunked up. The system runs and runs but doesn't cool well. You can spray them gently with a hose, but be careful not to bend the fins. They're real delicate.

Condenser fan motors burn out from working too hard in the heat. You'll know it's happening when you hear humming but the fan's not turning. Or it starts up then shuts off after a few minutes. The motor's probably overheating. Replacing one takes electrical know-how and the right parts.

Schedule professional HVAC repair when you notice problems with your outside unit.

Furnace Won't Light

Cold night and the heat won't kick on. Just great. Carrier furnaces are usually reliable, but they've got their common issues same as any brand.

Gas supply problems happen more than you'd think. Make sure the gas valve's open. Sounds obvious but easy to miss. If someone shut it off and forgot to turn it back on, that's your problem right there.

If the igniter cracks or breaks, the gas won't light. Newer Carriers use hot surface igniters instead of pilot lights. They glow orange when working right. If yours isn't lighting up when the furnace tries to start, it's probably shot.

Schedule gas furnace repair service as soon as you notice an ignition problem that you can’t fix on your own.

Blower Issues

Blower motors quit or act up at times on Carrier systems. Maybe it runs but makes noise, or it won't run at the right speed. Bad capacitors cause this a lot. That's the part that gives the motor its initial kick to start spinning. They weaken over time and eventually fail completely.

Limit switches shut the furnace down if it gets too hot. Safety feature to prevent fires. Problem is, they go bad or get triggered for other reasons. Dirty filters make the furnace run hot, trip that switch. Fix the real problem and the switch stops causing trouble.

Count on Sears Home Services to get to the bottom of blower issues quickly. Schedule service and we’ll have your Carrier system working properly again in no time.

Strange Noises

Carriers aren't usually noisy units when they're running right. New sounds mean something's wrong almost every time.

• Rattling usually means something's loose. Cover panels, duct connections, mounting bolts. Track down what's vibrating and tighten it up. Easy fix most times.
• Screeching or squealing points to bearings going bad in a motor or fan. Bearings aren't made to last forever, especially in the heat of a furnace or in the weather outside. They need replacement before they seize up completely.
• Booming sound when the furnace lights could be delayed ignition. Gas builds up before lighting, then whoosh! This is a dangerous situation. It could be a clogged burner or bad gas valve. Don't ignore this one – it can lead to bigger problems. Schedule furnace repair right away.
• Grinding noises almost always mean something's wearing metal on metal. Shut the system down before parts get damaged beyond repair. Usually it's a motor bearing completely shot, or something's come loose and is hitting the fan. Schedule service and a technician will fix the issue.

Thermostat Problems

Sometimes the issue isn't the Carrier unit at all. It's the thermostat telling it what to do.

• Batteries die and people forget that some thermostats even have them. The system just stops responding one day. Put in fresh ones every year whether they seem dead or not.
• Wiring comes loose, especially in older homes where things settle and shift. Tiny wires connect to little terminal screws inside the thermostat. They work loose and suddenly your AC runs all the time or won't come on at all.
• Programming gets messed up. People hit buttons without realizing what they've changed. The schedule gets altered or the system gets put in a mode you didn't want. Check your manual for the button instructions to program your system properly and adjust the settings.

Frequent Cycling

System running for just a couple minutes, shutting off, then starting again soon after? That's short cycling. Bad for equipment, bad for comfort, bad for your energy bills.

Oversized units cycle more than properly sized ones. If your Carrier's too big for the space, it cools too quickly, shuts down, then has to start up again soon. Not much to do about this except replace the system with the right size unit when it's time.

Dirty flame sensors make furnaces shut down right after lighting. They can't tell the flame is there, so they shut off the gas as a safety measure. Cleaning that sensor sometimes fixes it. You just need a bit of fine sandpaper and to know where to find the sensor.

Low refrigerant in AC systems trips the pressure switch. The unit shuts down to protect itself and tries to run again after a while. Round and round it goes. Finding and fixing the leak is the real solution, not just adding more refrigerant.

Carrier Heat Pumps

Carrier heat pumps have their own special issues. They cool in summer like an AC but also heat in winter by running the cooling cycle backward. Clever, but more complex.

Reversing valves stick or fail. That's the part that switches between heating and cooling. When it gets stuck, you might have cooling but no heat, or the opposite. Sometimes tapping on the valve body frees it up temporarily, but it'll need replacement eventually.

Defrost problems show up in winter. The outdoor coil needs to defrost periodically when it's cold out. Ice builds up, and the unit has to melt it off to work right. Defrost control boards fail and leave you with a giant ice block where your heat pump used to be. Not good.

Schedule heat pump repair service when you encounter heating or cooling problems with your Carrier system.

Ductwork Matters Too

The best Carrier unit in the world won't work right if the ducts are bad. We find this all the time.

Leaky ducts waste huge amounts of energy. Your expensive conditioned air just dumps into the attic or crawlspace. Sealing those leaks makes the whole system more effective.

Undersized ducts restrict airflow. Carrier units need the right amount of air moving through them. Too little flow and the AC coil freezes or the furnace overheats. Ductwork that's too small chokes the whole system.

When To Call For Help

Some Carrier HVAC issues you can handle yourself. Change filters, clean around the outdoor unit, check breakers, change thermostat batteries. Basic maintenance stuff keeps things running right.

But when it comes to electrical problems, refrigerant issues, or gas-related furnace problems, that's when calling us makes sense. Our techs work on Carrier systems every day. What takes you hours of frustration (and probably a few trips to the hardware store), we knock out quickly.

We keep common Carrier parts on our trucks. Our techs get factory training on all their systems. Plus we stand behind our work with solid guarantees. Your comfort's too important to mess around with trial and error fixes from online videos.

Give us a call when your Carrier system needs more than the basics. We'll get your home comfortable again without the headache of complex repairs. Too hot, too cold, too noisy - whatever the problem, we've seen it and fixed it countless times before.
