The winter of 2019 will go down as one of the coldest winters on record in Southeast Wisconsin, how did you fare during that time? Here is a fact… 98% of the homeowners that had Rosenthal perform their annual maintenance on their heating system did not have to call us because our technicians identify the small items that once repaired or adjusted prevent the larger costly breakdowns. How often do you go past the mileage warning label? Air conditioners are put through a lot over the cooling season and don’t forget, your furnace also works as hard blowing the air through the ducts. If your Furnace & Air Conditioner were a car, you’d be putting an average of 16,600 miles on it per year. That’s at least $245 of oil changes per year.

Preventative maintenance on your Air Conditioning system is no different than changing the oil on your car. It's required if you want your equipment to last. Manufacturers recommend your air conditioner and furnace should be maintained every spring & fall as part of their terms & conditions of their warranties. With the warm summer temperatures approaching, it’s time to make sure your Air conditioning system is clean and inspected and ready for summer. Because I believe in the benefits of seasonal maintenance, I will reduce the cost of our $109 Precision Air Conditioner Tune-Up. But don’t wait until you have a costly breakdown!

Rosenthal Heating & Air Conditioning is here for you! Call today to scheduke your A/C Maintenance!

A Clean Air Conditioner Pays You Back!

Heating & Cooling equipment manufacturers recommend annual maintenance as the best way to prevent your air conditioner from breaking down. They designed the product; therefore, they know as .042 inches of dust build-up in the machine will lead to an efficiency drop of up to 21%. A 21% efficiency drop can end up costing you over $209 in energy costs. Furthermore, the outdoor unit in your backyard makes a great winter residence for mice and insects that can-do costly damage, if gone undetected.

Air conditioner tune-ups have loads of benefits that you won’t ever think of if you don’t think about your AC until something goes wrong with it. Rosenthal Heating & Air conditioning can save money on your home’s energy costs as well as air conditioner repairs. You’ll also be making sure that your AC unit, which is very expensive, will last much longer and be more efficient during that time. You won’t see nearly as many breakdowns of the machine, and it’ll be much easier to keep your home cool during the summer months.

Just as your heating system works great after a technician gives your furnace an annual tune up, your AC system feels great after a similar testing, adjusting and cleaning, too.

Service plans offer reassurance that your bank account won’t be exhausted if your AC system develops any unexpected problems throughout the summer.
