Sun Prairie’s No. 1 HVAC Services Company

Helping Sun Prairie residents with heating and cooling for over 65 years

Sun Prairie’s heating and cooling professionals

As the birthplace of painter Georgia O’Keefe, Sun Prairie has made quite a name for itself as a thriving small town with easy access to the metropolitan amenities in nearby Madison. It’s also among the “Top Places to Live in America,” due in part to its four-season weather.

When temperatures swing from spring to summer, fall to winter, and back again, HVAC problems are bound to appear. We want you to feel comfortable in your home. We’ve spent more than 65 years servicing Sun Prairie homes, so there’s no problem too big or too small for us to handle. Just give us a call.

We’ll provide you with a quick, in-home inspection and give you a repair or installation estimate that’s fair.

Don’t wait to fix furnace problems, call today!

Every winter, we hear stories of people who try to fix their furnace problems on their own or have taken extreme measures to keep warm during a furnace breakdown. Some of these actions, such as using an oven to warm a home, or filling it with faulty space heaters, are downright dangerous. In Sun Prairie, our heating experts can help you identify the most common furnace problems, including:

  • Taking too long to kick on: Most furnaces should kick on and start warming your home within five minutes.
  • Blowing out cold air: You could be having pilot or ignition control problems.
  • Funny smells or noises: A furnace with a clogged or dirty filter can make your heating system work harder than it needs to be, and develop airflow problems. Filters should be replaced every 90 days.

It’s important to ensure your furnace is functioning, energy-efficient and most of all — safe. Don’t put your family’s health at risk. Call Harker’s heating experts.

Air conditioning service and repair

In Sun Prairie, we may not need our air conditioning system as long as our heating system, but it’s equally as important. Over the past few years, summer temperatures have been on the rise making air conditioning a home necessity rather than a luxury. According to a report, central air conditioning is fast becoming more commonplace among Wisconsin households. And as more people turn to central air to cool their homes, there’s likely to be air conditioner problems along the way.

Before you decide to DIY, recognize the signs of an  a/c breakdown signs, including:

  • Inadequate cooling and poor airflow
  • Water leaks and/or heavy condensation
  • Icy refrigerant lines
  • High energy bills

Before summer kicks in, we can conduct air conditioning maintenance and help change your air filters to ensure that these issues don’t lead to equipment failure.

Why indoor air quality matters for your home

With families spending as much as 90 percent of their time indoors, it’s important to maintain a home with healthy air quality.

In summer, high humidity rates can increase the prevalence of mold and plant allergens in your home. And in winter, a lack of fresh air can trap allergens, vapors, and pet dander, leading to poor air quality — and potentially heart or respiratory problems.

At Harker, we want your family to be comfortable and healthy. If you’re cleaning regularly, vacuuming and dusting, and using non-toxic chemicals, and are still experiencing indoor air quality problems, call the IAQ specialists at Harker. We can help you choose an air quality system that is right for you.

Hot water issues leaving you cold?

s your hot water heater more than 10 years old? Are you finding sediment in your drains? Is your water turning a rusty color? Are you waking up to shower that’s cold? These are water heater failure signs you shouldn’t ignore. While we’re happy to offer 24/7 emergency repair services, learning the signs can help you prevent a messy (and costly!) disaster.

If your water heater is more than 10 years old, however, you may want to consider a new hot water heater replacement altogether. Our HVAC technicians can help you determine whether to spring for a repair or replacement with a system that’s perfect for your home.
