We Service and Install Heating and Cooling Systems

Your HVAC system may have been going strong for years; however, at one point or another, it will break down.  It may require a simple repair or cleaning, or the entire system may need to be replaced.  Rock Valley HVAC, Inc. will be there to make it right through expert heating and cooling services. We understand that your air conditioner is a must during the summer.  In addition, you cannot live without a functioning furnace during the winter.  So we make sure to come to you as soon as possible and ensure that we get the job done right, the first time.

If you are building a new home, we also provide air conditioner and furnace installation. With a commitment to our customers’ ultimate satisfaction, we will take the time to fully gather what it is you’re looking for in a new heating and cooling system.  Next we will give you options so you can choose what fits your budget.  This being said, we provide free quotes on new equipment purchases for a new home build or a replacement of your existing HVAC equipment.

On the other hand, there is a fee for services and repairs.  As a result, we will keep you informed of the work that needs to be done and what the costs will be. But, you will not be overcharged or hit with a hidden fee.
