Heating & Air Conditioning

Rozga Plumbing & Heating Corp.'s HVAC division handles installation and service, new construction, remodeling, replacement and repairs. We have a complete sheet metal shop, and are able to design complete heating and air conditioning systems for both residential and commercial jobs. Our technicians have decades of experience in the heating and air conditioning trade. We offer free estimates for replacement and new construction as well as annual service agreements for routine maintenance.  When you hire us we will provide you with a trustworthy crew that take great care when we are in your home!  We offer options regarding many types of home comfort needs.

To me there is nothing quite like spring weather.  Sunshine, grilling outside, yard work, birds and wildlife all around.  I think spring is my favorite season.  For us, spring brings lots of tune ups on Air Conditioners and replacements of those old, rattling, inefficient units.  You know what I am talking about.  If you don’t know how old yours is or just need a good cleaning and refrigerant check, give us a call.  Many folks don’t realize that R22 refrigerant or FREON is being COMPLETELY phased out.  Pricing has steadily gone up each year of the phase out.  Don’t wait.  If yours is newer there are regular maintenance items that need to be replaced on your AC unit such as contactors, capacitors, and hard start kits among others.  Don’t be caught on the hottest day of the month with your system down and everyone sweating because you didn’t have a service checkup. 

Air Duct Cleaning

We also offer RotoBrush Duct Cleaning Services.  We start by removing and cleaning the registers.  Then we insert our brush/vaccuum head combo into the ducts where the brush spins and pulls the head through the ductwork.  Once we are all done with the main floors we move to the the basement to create access ports to clean the main trunk lines.  After this is complete we spray an antibacterial mist into the system.

We know there are many other heating and cooling companies but we have learned that nothing is better than referrals so please check out our testimonials page to hear from many of our other happy customers.

We are an accredited member of the Wisconsin Better Business Bureau and have earned an A+ rating.  We have also received an Angie's List Super Service Award for the past 5 years!

Carbon Monoxide Detectors

If your home does not currently contain a carbon monoxide detector, please consider purchasing one. Carbon monoxide is odorless and can cause you and your family physical harm. Even low levels can cause fatigue and increase chest pain in people with chronic heart disease. We recommend the low-level carbon monoxide detectors. They are also recommended by the American Lung Association and are currently a requirement. To find out more, call us at 414-258-9911.  We can install one or more at our next tune up for your furnace.
