Fitchburg’s Leading HVAC Services Provider

Fitchburg’s heating and cooling professionals

In Fitchburg, we get the best of both worlds: close enough to enjoy all the perks of the big city, but just a stone’s throw from the fresh air and quiet we crave in the countryside. It’s a great place to watch the turn of the seasons — until your home furnace or air conditioning unit goes awry.

With Harker, our HVAC specialists are here to solve all of your heating and cooling issues. We’ve serviced Fitchburg neighbors for more than 65 years, so there’s no problem that’s too small or too big for us to handle. When you’re faced with heating cooling problems, don’t wait or try to fix it yourself. Turn to the experts at Harker.

Providing routine furnace maintenance to bigger fixes

When temperatures begin to drop in Fitchburg, it can seem like a daunting task to get your furnace back in working order. But it’s important to ensure your furnace is as safe, functioning and energy efficient as possible. Fortunately, our HVAC specialists are available for routine furnace maintenance. Harker’s furnace experts will inspect your furnace unit, change your filter, and ensure there are no dangerous leaks or problems that could affect the health of your family or home.

Harker provides heating maintenance, 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)

Be on the lookout for strange noises, cold blowing air, funny smells; these are all signs of a furnace breakdown. And if your furnace happens to go on the fritz, you know who to call.

Air conditioning service and repair

Your furnace isn’t the only piece of equipment that needs regular routine maintenance — so does your air conditioner. Up to 80% of air conditioning compressor issues could be eliminated if the problems that lead up to the a/c breakdown were addressed in a timely fashion. At Harker, we suggest calling for an air conditioning inspection in spring. Regular a/c maintenance can help your system run longer, and ensure that you’re not paying more in energy costs than you should. A dirty air conditioner, for example, can more than double your bills, without providing you with a cool and comfortable home.

HVAC experts suggest homeowners change their A/C unit’s air filter every 60-90 days — especially if you own pets. Otherwise, your air conditioner unit could start to collect direct and affect its functionality.

If you’ve already replaced the air filter and still notice low airflow, condensation, or increasing energy bills, call the A/C specialist at Harker. We can help identify and fix the problem, fast.

Protecting your family with indoor air quality solutions

Living in Fitchburg, with its vast network of parks and recreation trails, there is always a reason to get up and head outside as a family. But winter leaves many of us wanting to curl up at home, instead. This can lead to poor indoor air quality.

Because homes are built to be energy efficient — keeping warm air out in the summers, and keeping out the cold in winter — they are also built to keep out health, fresh air, allowing pollutants, allergens and pet dander to build up and cause health concerns.

Despite popular belief, furnace and air conditioning filters don’t actually clean your home’s air. To keep your home free of indoor air quality problems, you should:

  • Dust and vacuum regularly;
  • Use non-toxic cleaning products and low-to-no VOC chemicals; and
  • Install an air purifier.

Harker’s IAQ specialists can help you figure out whether a portable air purifier is best, or if your home is better suited for a whole-home air cleaning system.

No hot water? Harker can help

When you live in a city that sees subzero winter temperatures, there’s nothing worse than waking up with hot water heaters, or no water at all. Don’t get left in the cold — call Harker’s team of hot water heater experts. A water heater may be showing signs of trouble if:

  • Your hot water heater is more than 10 years old;
  • Your heater is making strange noises, such as rumbling or knocking;
  • You notice rust-colored water, which indicates corrosion; or
  • Water is beginning to pool around the tank.

Our HVAC technicians can repair and replace electric and gas hot water heaters at a cost and timeline that’s reasonable for you, so you can get back to relaxing in a hot shower fast.
