Emergency Furnace Repair When You Need It Most
Winter in Middleton can be brutal. When your furnace breaks down during a cold snap, you don’t have time to wait for an appointment next week. Our emergency furnace repair service is available around the clock because we know heating emergencies don’t follow business hours.
A furnace breakdown isn’t just an inconvenience—it’s a safety concern. Families rely on their heating system to keep their homes warm enough to prevent dangerous conditions. Whether your furnace stopped working completely, is making strange noises, or isn’t producing enough heat, our furnace repair specialists in Middleton can diagnose the problem and get it fixed fast.
Sometimes a repair is all you need. Other times, a furnace replacement makes more financial sense. As your local HVAC contractor, we’ll give you an honest assessment of both options so you can make the best decision for your home.
24/7 emergency furnace repair
One minute your family is enjoying a cozy winter evening, and in the next you’re fretting about a furnace breakdown. When your furnace is functioning properly, it often falls off the radar — until it doesn’t. Whether you failed to conduct regular maintenance on your heating system, or your furnace is simply outdated, Harker is available to provide emergency furnace repair or replacement with the ease of a phone call.
In Middleton, a broken down furnace combined with freezing winter temperatures is a recipe for dangerous conditions. If your furnace stops working in your home, don’t wait. Call the heating experts at Harker.
Professional Air Conditioning Service for Middleton Summers
Wisconsin summers are getting hotter. If you’ve noticed that your air conditioner isn’t cooling as efficiently as it used to, or if you’re considering upgrading to a newer unit, our cooling contractors in Middleton are ready to help.
We provide complete air conditioning services, including:
- A/C Installation – We’ll help you select the right cooling system for your home’s size and layout, then install it properly for optimal efficiency
- Air Conditioner Repair – Strange noises, warm air, refrigerant leaks, or reduced cooling efficiency? We’ll find the problem and fix it.
- Air Conditioner Maintenance – Regular tune-ups keep your system running at peak performance and can extend its lifespan by years
An air conditioning system that’s properly maintained runs more efficiently and lasts longer. Many homeowners skip maintenance until something breaks, then they’re stuck with an expensive emergency repair or replacement. As an HVAC contractor in Middleton, we recommend annual maintenance before the cooling season to catch small issues before they become big problems.
Is your air conditioner ready for rising temps?
Did you know that annual temperatures in Middleton have raised an average of 1.6 degrees from the first half of the 1900s? As our summers get warmer, it’s no surprise our cooling specialists have fielded an increase in air conditioning service requests. When temperatures are intolerable, you want to be able to rely on your home’s air conditioning system. If your A/C unit is outdated, or if you’re noticing leaks, funny noises, or warm blowing air, talk to our cooling specialists or visit our showroom today. We carry a full line of air conditioner systems fit for your home.
Heating and Cooling Systems That Work Together
Not all HVAC contractors understand the full picture of your home’s comfort needs. At Harker, we look at your entire heating and cooling system as an integrated whole. This means considering factors like:
- Ductwork efficiency and proper airflow
- Thermostat placement and programming
- Zoning systems for balanced comfort throughout your home
- Indoor air quality and ventilation
A new furnace paired with old, leaky ductwork won’t perform as well as it should. A top-of-the-line air conditioner can’t cool properly if your home isn’t well-sealed. Our heating and cooling contractors in Middleton take a comprehensive approach to ensure every component works together efficiently.
Indoor Air Quality Solutions That Matter
Allergies, asthma, and respiratory sensitivities are more common than ever. If your family is suffering from constant sniffles, dry skin, sore throats, or sinus issues, the problem might be your home’s indoor air quality.
We offer several solutions to improve the air you breathe:
- Whole-Home Air Filtration – Captures dust, pollen, pet dander, and other particles that recirculate through your home
- Humidifiers and Dehumidifiers – Maintain proper humidity levels for comfort and health
- Fresh Air Systems – Brings clean outdoor air into your home while exhausting stale indoor air
- Radon Mitigation – Protects your family from this invisible, dangerous gas
Many homeowners assume they have to live with seasonal allergies or dry air. You don’t. Our IAQ specialists can assess your home and recommend solutions that will make a real difference in how your family feels.
Improve your home’s air quality
With warmer temps in Middleton comes longer allergy seasons. If your family is suffering from the sniffles it could be more than a pollen problem, however. It could be your home’s indoor air quality. There are a few steps you can take to improve your home’s air, such as:
- Opening your home’s windows to ventilate the air
- Changing your furnace filter every 60-90 days
- Vacuuming and dusting furniture, drapes, and floors regularly
We know you want your family to breathe safe, clean air. If you or your family members are still experiencing physical symptoms such as sore throats, dry or itchy skin, or sinus irritation, you may want to consider investing in a fresh air system. See one of Harker’s IAQ experts, who can show you our indoor air quality solution options, including whole-home air cleaners and portable filtration units.
Water Heater Repair and Replacement
Is your water heater showing its age? We provide complete water heater services for Middleton homes and businesses, including:
- Water heater repair and maintenance
- Traditional tank water heater replacement
- Energy-efficient tankless water heater installation
- Water heater flush and sediment removal
A failing water heater can leave you without hot water at the worst possible time. We recommend having your water heater inspected annually, especially if it’s more than 7-10 years old. Early detection of problems can save you thousands in water damage and emergency repairs.
We do water heater repairs, too
Are you noticing rusty-colored water streaming out of your faucet? Is sediment piling at the drain? These are both common signs of a hot water heater in need of maintenance and repairs — or replacement.
While discolored water doesn’t always spell disaster, it’s best to call on the HVAC experts at Harker to help you find the water heater problem. We can help you discover the cause of corrosion, flush your water heater system, and check your heating elements to ensure that everything is running smoothly. And if your water heater equipment is more than 10 years old, we can also help you find a new water heater system that works for your life.
Harker provides traditional water heaters, as well as geothermal heating options for your convenience and comfort. Call us for an in-home estimate today!

Questions Homeowners Ask About HVAC Service
How often should I have my HVAC system serviced?
We recommend annual maintenance—ideally a furnace check-up in the fall before heating season and an air conditioning tune-up in the spring. This keeps both systems running efficiently and helps us catch small problems before they become expensive repairs.
What’s the difference between repair and replacement?
If your system is relatively new and needs occasional repairs, fixing it makes sense. Once a system reaches 15+ years old, repeated repairs often add up to more than the cost of replacement. We’ll always give you both options so you can decide what’s best for your budget.
How can I lower my HVAC costs?
Regular maintenance is the single best way to keep your system running efficiently and extend its lifespan. Proper thermostat settings, weatherization, and keeping air filters clean also make a big difference. Our team can recommend specific upgrades that will pay for themselves through energy savings.
Is your HVAC contractor company licensed and insured?
Absolutely. All our technicians are properly trained and certified. We’re insured and bonded, and we stand behind our work with warranties and guarantees.
Can you help with emergency repairs?
Yes. We’re available 24/7, 365 days a year. If your heating or cooling system fails, call us, and we’ll get a technician to your Middleton home as quickly as possible.
