HVAC Maintenance in Chicagoland

If you’re like many McHenry-area homeowners, you only give thought to your HVAC system when something goes wrong. However, this type of reactive maintenance can actually be a costly way to handle your heating and cooling system.

How Often Should I Have My Chicago HVAC System Serviced?

While the answer to this question partially depends on what type of HVAC equipment you have, most systems need to be professionally maintained at a minimum of yearly. This means that you should schedule air conditioner maintenance in the springtime, and furnace maintenance should be scheduled in the fall to cover all of your bases. In the case of a heat pump system, which runs all year long, you would need maintenance twice—once in the spring and once in the fall to cover the same needs as a conjoined forced-air system.

Save Money by Investing in HVAC Maintenance

One of the major hassles of scheduling an annual HVAC service—besides remembering to do it in the first place—is having to shell out time and time again for one at a time services. A single maintenance visit can cost hundreds of dollars at a time, depending on who you’re scheduling service with. It’s still worthwhile to be sure, but there’s a better solution!

HVAC maintenance agreements roll your yearly AC maintenance and furnace maintenance needs into one easy monthly payment. Together with these savings, and the savings you stand to gain from avoiding costly repairs and reducing energy waste, our contractors can say will full confidence that setting up a recurring HVAC maintenance service contract.

And that’s not all you get out of a maintenance contract. Together with all of the bonuses that Black Diamond offers, your HVAC system will also benefit from:

  • More efficient operation – A properly maintained system will operate at its most efficient level, helping reduce your energy expenditures.
  • Longer lifespan – Get the most years out of your system by keeping it functional and well maintained.
  • Less cost for repair – Not only will the system have a lesser need for repairs, but with a maintenance check each year, you can also spot small problems before they develop into big ones.
  • More comfortable home – A maintained system will more evenly heat and cool your home, contributing to your family’s overall comfort.
  • Peace of mind – You can enter the heating and cooling season knowing that a trained professional had checked your system top to bottom!
