Get an AC Unit that Actually Works

A new central air conditioning unit means lower bills, improved air circulation, and less humidity. Martens can replace your old, inefficient air conditioner with a new high-efficiency unit — without the headache or financial stress. Or, if you currently do not have a central air conditioning system, our team can evaluate your home and recommend a unit that will keep you cool for years to come.
The unit that’s right for you will keep all areas of your home cool. The size of the system, installation, and ductwork, will have an impact on how well your system works. We’ll help you find the right fit for your home, taking square footage, energy needs, and your budget into consideration.
We believe in exceptional service and work, making sure the end result exceeds expectations without breaking the bank.
Where Craftsmanship Meets Innovation
Martens Heating & Cooling is your go-to company for air conditioner installation services in and around the Fox Valley, WI. With 40+ years in the business, we are well versed in a wide-variety of air conditioning options.
In today’s market, it seems that everybody has some type of air conditioner. Although those window units are readily available and affordable, they are costing you more money. They are far less efficient than central air conditioning and don’t offer the same effectiveness. Even a large window air conditioner, capable of cooling bigger spaces, won’t provide consistent cooling. The area directly in front of the unit will be freezing, while another area will be warm.
If your home does not have a duct system or there are areas such as additions or bonus rooms where duct work is not an option, then a ductless system may be the answer for you. These units are energy efficient and much more capable of maintaining a uniform comfort level than a window unit. Ductless systems have built in heat pumps that are capable of maintaining comfortable temperatures inside, even when outdoor temperatures are as low as -20 degrees.
We can build completely customized air conditioner ductwork solutions for your HVAC needs. Our metal fabrication shop allows us to design and modify any new system, so that it fits your needs. We also install ductwork in residential and commercial buildings.
What Our Customers are Saying
When To Consider an Air Conditioner Replacement
When given a choice most homeowners are going to want to repair a unit over replacing it. Unfortunately, there comes a time when repairing is no longer an option.
If you find you need someone out to service your system more than once a year, it may be time to replace it. The cost to repair will get to the point where it will supersede the cost to replace.
As a machine gets older it can struggle more to cool your home. This struggle can mean a higher bill. If you notice a spike in cost that’s not normal it may be time to replace.
Air conditioning units are specific to the dimensions of your home. If a unit is too small it won’t effectively cool the house. If you’re adding more square footage, your system may not be able to handle it and may require a replacement unit.
The average lifespan of an air conditioner is 10-20 years. As you get closer to that 20 year point, your AC unit may be on its last legs. It’s not a matter of care and repair at that point, replacing the unit may be your only option.
