Time To Schedule Your Furnace Clean in Naperville


It makes the FURNACE and electronics work harder to warm your home, its FAR less efficient, and drives UP utility costs every month. There are 3 solutions:

1) Call Harmonic HVAC for a Seasonal "CLEAN & CHECK". Normally $119, mention the "Early Bird Special" and take $25 OFF. So its only $94!


2) Join Harmonic's signature "Rock*Star Maintenance Plan" and $AVE even MORE money! Rock*Stars only pay $85 in the Spring + $85 in the Fall. That's right, only $170 p/yr. PLUS a TON of discounts on parts and labor.


PLUS you can earn $250 credit toward a new unit. PLUS you get "Rock*Star" treatment with after-hours and priority scheduling, exclusive to Rock*Stars.


3) If its "that time" (if you book in MAY) we will take $500 OFF the price of your A/C + Furnace COMBO installation! But you have to schedule your install for OCTOBER 2021.


So CALL 630-999-9008 TODAY... or Visit HarmonicHVAC.com for more information!
