The $89 Service Call Solution

Many air conditioning companies offer “Service Calls” for $29.99 or even as low as $19.99. Unfortunately, these “too good to be true” service calls are exactly that.   Here’s the only way it works for companies that offer these ultra low service calls:

For the low price, they send you a “Technician”, who is really a salesman to your home.   His job is not just to “diagnose” the problem, but to up sell you on things that you don’t need or charge you an outrageous price for the repair.

Our $89 Service Call is the solution to avoiding the high pressure sales for parts and services you don’t need. Dan and Jon are real technicians who will thoroughly diagnose your system and repair it. Most of the time it is only $89 plus the part at a fair price.

We offer straight forward, reasonable pricing and don’t pressure you into unnecessary upgrades.  If it sounds too good to be true then it’s probably not true.

A family-owned and operated business with more than 30 years of experience, Sims Heating & Air has the expertise to repair, maintain and install home heating and air conditioning equipment and HVAC ducting and vents. Whether you need maintenance for your existing air conditioner or furnace, or an entirely new heating or cooling system, we ensure that the comfort and reliability of our work meets our high standards, and exceeds yours.
