Air Conditioning Repair and Maintenance

AC Repair

We’re familiar with every common AC problem. Wear and tear, mechanical strain, and undiagnosed issues can cause your air conditioner to blow warm air, not blow enough air, or become noisy. A leak, frozen coil, or odors from the system are reasons to contact us for repairs as well, but don’t only wait until there’s a problem. We can help with maintenance and provide AC tune-ups to avoid major issues.


AC Installation

Only if your air conditioner is properly sized and installed will it provide the comfort that you need. Our technicians will fully evaluate your home and, once the system is installed, test your AC to ensure it performs as it’s designed to. Our priority is to guarantee you are completely satisfied with our work.

AC Replacement

Replacing an air conditioner is an expense most homeowners wish to put off. But if your AC has reached the end of its life, or is not running efficiently, a new unit can save you money over the long term. We install packaged systems, ductless mini split systems, and heat pumps.

Furnace Tune Up Process

Furnace Repair

Being without heat in a Wisconsin winter can be dangerous. Fortunately, we can schedule service quickly and make any repairs necessary. Request service if you’re getting inconsistent heating. If your furnace breaks down, runs continuously, makes strange noises, or your carbon monoxide alarm goes off, call us for immediate help.

Furnace Installation

We install electric, natural gas, and oil furnaces. You’ll get a complete estimate and walkthrough of the installation process before we start. Gas, electrical, and HVAC connections will be inspected and, if necessary, repaired and updated; we’ll also check and improve upon ventilation in your home.

Carrier Furnace Repair

Furnace Replacement

Replacement is often an opportunity to upgrade to a better suited, more efficient furnace for your home. A well-maintained furnace can have a 15–20-year lifespan. Consider replacement if your furnace is making loud noises, emits odors, or requires frequent repairs. A rise in energy bills may mean it’s no longer working efficiently.

These guys came in as a second opinion for my HVAC system and were so informative. Thank you so much! Now my new condo has a new system that I know will last.

We are having a fireplace installed, and In-Phase was the ones we trust to install the electrical for it. They are not only professional, but highly skilled and personable as well. They always go above and beyond! Josh was great!

Joe from Over the Moon changed our smoke detectors and replaced an outlet. He also did an annual inspection. Joe was very efficient and knowledgeable. He explained everything he was doing and suggested some changes that could be beneficial. I would highly recommend Joe and Over the Moon!

James Bomberg

We had Over the Moon do a maintenance service on our AC system. Took advantage of their $99.00 service special. The technician Mike was professional, courteous and did a thorough job. We have had Over the Moon into our home for other services and repairs. We are satisfied with their performance, honesty and integrity.

Jim Paro

Over the Moon is outstanding. They did extensive work for us in a number of areas in our home, some quite complicated. Expert service, way above quality of other contractors we have used in the past. Highly recommended. Our service provider Joe is the best!
