Furnace Installation and Repair

Don't let your heating system leave you frozen this winter. The HVAC Experts at Aasen Heating & Cooling have you taken care of for any furnace repairs in Oconomowoc.

When your furnace won’t switch on, we’ve learned you can occasionally take care of this problem without help. Go through our uncomplicated troubleshooting guide before calling us at (262) 567-4243.

4 Things to Check When Your Furnace is Malfunctioning:

Thermostat settings: Make sure it’s positioned on “heat.” Otherwise, the thermostat won’t signal your furnace to begin heating.
Furnace filter: A clogged filter can cause your furnace to overheat and shut down as a safeguard. It can also stop it from creating and spreading heat.
Circuit breaker: Your furnace’s breaker may have tripped. Locate it on your home’s electrical panel. Reset it if the breaker is in the middle or “off” position.
Furnace switch: Your furnace has a switch on or near it that appears to be a regular light switch. It should be in the “up” or “on” position. If it was turned off, give your furnace a few minutes to resume normal operation.

If your furnace still isn’t working accurately, give us a call, and we'll send one of our highly-trained techs to diagnose and correct the issue!

When it’s time to upgrade your gas furnace, the experts at Aasen Heating in Oconomowoc have you covered from start to finish. We’ll help you find a quality furnace that’s right for your home and budget!

Today's gas furnaces are energy efficient. Some of our high-efficiency furnaces feature quiet, variable-speed technology. By heating at multiple speeds, the furnace adjusts the heat flow throughout your home. This increases comfort while potentially using less energy and optimizing indoor air quality.

When appropriately maintained with periodic tune-ups, a new high-efficiency furnace can be expected to last and limit the need for pricey trip charges, and may be more budget-friendly than you expect. Especially when you keep in mind our great financing plans and the potential for long-term energy savings!

Air Conditioning

We'll help you beat the summer heat, whether that's fixing up your current AC or looking for something new!

When your air conditioning system suddenly stops working, you may automatically assume the worst. But major repairs are not always necessary.

Sometimes, the problem can be something simple, like a clogged air filter or a tripped breaker. Here are some of the most frequent causes of a sudden air conditioner failure:

Thermostat problems: An incorrect set thermostat, a faulty thermostat, or a digital thermostat with dead batteries may prevent the system from turning on.
Tripped breaker: On especially hot days in the Charlotte area, it is not unheard of for the air conditioner to trip the breaker at full load.
Poor airflow: Poor airflow due to a dirty filter, blower problems, or duct obstructions can put extra load on the system, causing the compressor to overheat and shut the system down.
Clogged condensate drain: If condensed water accumulates in the drain pan due to a clogged condensate drain, a float switch may turn the system off for safety.
Frozen evaporator: Often caused by poor airflow or low refrigerant, a frozen evaporator can cause the compressor to overheat and shut the system off.
Improper refrigerant charge: Low or high refrigerant pressures could trip a safety switch and shut the system down.
Compressor problems: A damaged AC compressor, relay, or start capacitor could prevent the system from running.

If the problem cannot be fixed by adjusting the thermostat, replacing the air filter, or resetting the breaker, you may need professional assistance. Give us a call and we'll be happy to assist!

If you're looking for repair or replacement of your old AC unit, you've come to the right place. Our technicians will diagnose your problem, replace parts or complete units, and get your air conditioning system back up and running.

Extremely happy with the installation of the new air conditioner. The crew was always on time, pleasant to work with, careful not to damage or make a mess, and just a totally different experience than working with other contractors. Would recommend to anyone and everyone. Already have. Five stars.
Robert L.

I worked with Todd to upgrade a thermostat and add a few zone sensors in a property I manage in Oconomowoc. Todd was very responsive over the phone and by text. I was able to get the work scheduled in the time frame desired, and within my budget. I would definitely work with the Aasen Heating & Cooling team again. Thanks for all your help!
Matt K.

Todd and his team did an outstanding job replacing my a/c unit. I wouldn't hesitate to call Aasen Heating and Cooling again for any of my future hvac issues.
Chongyee Y.

I have used Aasen Heating & Cooling for heating duct cleaning, furnace maintenance, and for purchase and installation of a new central air conditioning system. I have always been very happy with their work, and felt their pricing was very good. Highly recommended! I got to know the original owner, Pete Aasen, very well over the 8 years I have lived in the area. He was an exceptionally good man, and he will be sorely missed.
Scott H.

I want to thank Todd and Matt for taking such good care of my problem. Matt has always done a great job. So good to be cool today. They are always there for you.
