News & Advice


It makes the A/C work harder to cool 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 $250 OFF the price of your A/C or $500 OFF the price of your A/C + Furnace COMBO installation! But you have to schedule your install for MAY 2021.
