Fixing the most common furnace problems — to the most complex
Is your furnace blowing cold air? Is the blower continuously running? These are both common signs of a furnace breakdown. But before you call in the professionals, however, turn off your furnace and check the furnace filter. A dirty air filter restricts airflow, which can cause your furnace to overheat and signal safety controls to shut down the burners. If you find the air filter in good shape, or you’ve already replaced the dirty air filter with a new one, and you’re still experiencing furnace problems, it’s time to call the heating experts at Harker. Harker provides heating repairs and replacement services for:
- Furnace systems
- Gas and oil boilers
- Fireplaces
- Heat pumps
- Garage heaters
- Geothermal heat pumps
- Radiant heat systems (must connect to a boiler)
Looking for air conditioning service, instead?
Similar to your furnace, air conditioner problems often stem from having a dirty air filter. HVAC experts suggest that homeowners replace an A/C unit’s air filter every 60-90 days — especially if you have pets. Otherwise, your until could become caked in dirt and grime, and begin to fail. If you’ve already replaced the air filter and still notice low airflow from air vents, leaking water, ice on refrigerant lines, or extra pricey energy bills, it’s best to bring in an A/C specialist to help you troubleshoot the problem.
At Harker, we provide both whole-home air conditioning systems and localized cooling options for smaller rooms or homes. Our air conditioning experts can help you find a system that is right for you.
Protecting your family with indoor air quality solutions
While air conditioning filters protect your A/C unit, they don’t actually clean your home’s air. To keep your home free of dust, allergens, and pet dander, you’ll need to take a few additional steps, including:
- Vacuuming the carpets and sweeping the floors daily;
- Regularly cleaning bedding, drapes, and furniture, where dust and allergens gather; and
- Cleaning your air ducts to remove dust build-up. (We can help with that!)
You can also invest in an air purifier. These systems can be adapted to upflow or horizontal duct configurations, split systems, closet installations or attached to roof-mounted, slab-mounted, or attic air-conditioning units.
Don’t get left in the cold — we fix water heaters, too
When Madison experiences sub-zero temperatures, waking up to an icy shower can throw off your whole day. Don’t get left in the cold — call Harker.  Hot water heater problems can be caused by a number of things including pilot light issues, sediment build-up, or a leak in the gas line, which aren’t always an easy — or safe fix for you to do on your own.
Our hot water specialists can repair and replace electric and gas hot water heaters at a cost that’s affordable for you, in a timeline that gets you back in a hot shower fast.
