Your American Standard Customer Care Dealer

Our philosophy is simple: we treat our customers the way we'd like to be treated.

We show our respect by showing up on time, being prepared, doing quality work, and treating your home as if it was our own. When we’re done, you pay what was agreed upon up front and can count on us stand behind our work. When you couple that with our dedication to our customers, why would anyone in the Delafield area go anywhere else? — If we’re the kind of HVAC company you’re looking for, give us a call or send us an email to tell us more about your heating problem!

PREVENT HVAC BREAKDOWNS
Like your car, your home’s mechanical systems work longest and best when they receive regular maintenance.

Frequently Asked Questions
How Long Do
Furnaces Last?
Furnaces Last?
Your typical furnace has a lifespan of roughly 20 years. How often the unit is used and the load put on it can impact this lifespan. Projected lifespan can be extended via annual preventive maintenance.
How Much Does
AC Service Cost?
AC Service Cost?
The cost of your AC repair or installation depends on many factors that are rarely, if ever, the same. Because we need to do an onsite assessment, we cannot provide quotes over the phone. Call us and we’ll get you scheduled to get a quote in the Oconomowoc and Delafield area.
How Often Should I
Check My Air Filters?
Check My Air Filters?
You'd be amazed how many HVAC problems are caused by someone forgetting to change their air filter. If you use a 1-inch disposable filter, we suggest replacing those monthly. For people with a 4-inch media filter, two changes a year is often enough.
When Should I Call
for Furnace Repair?
for Furnace Repair?
If your furnace isn’t heating as well as it used to, making strange noises, or refusing to turn on, it’s time to call us. Our HVAC expert can quickly uncover what’s wrong and recommend a solution. Just call Grenz Service Co. to get started.
How Long Will
My AC Unit Last?
My AC Unit Last?
While the lifespan of a new AC unit varies based on make and model, most will last between 10 and 15 years. Some systems not subject to heavy, constant use can last over 20 years if properly maintained. That doesn’t mean, however, that you should wait for it to break. Old units are often inefficient and expensive to repair. Being proactive about AC replacement is a great way to save money on your utility bills.
What Should I Check
Prior to Calling?
Prior to Calling?
Before contacting Grenz Service Co. for furnace repair in the Delafield area, go through the basics. Make sure you don’t have a dead thermostat or a tripped breaker.
