HVAC Replacement Process

At 4 Service Pros HVAC, we make air conditioning installations as seamless as possible for our customers. The first step is to contact us to schedule an appointment with one of our experienced HVAC expert technicians. A load calculation (HVAC replacement cost estimator) will then be performed so that we can properly size the right AC unit for your home or business. Without performing this calculation or performing it incorrectly can greatly affect how well your comfort level will be as well as affect your energy costs. It needs to be done right.


Once the load calculation is completed and the size of the unit or units is determined, we will be able to recommend the right brand cooling unit that will work best for you. We also provide financing options. Having a new AC unit installed is usually a big investment, so we are mindful of the fact that cost is usually high on customers’ lists.

All aspects of the air conditioning system will be carefully inspected. We want to make sure everything is properly working per the manufacturer’s guidelines. You as the customer are 100% satisfied with the installation and you made the right choice in selecting 4 Service Pros HVAC as your Air Conditioning Contractor for your AC unit replacement.
