Choosing the Right A/C Contractor
Is your air conditioning system old, unreliable, and expensive to repair? Do you want to lower your utility bills and ensure your family has clean, fresh air? These are compelling reasons to replace your A/C unit.
Because your HVAC system is one of the most complex systems in your home, it’s crucial to choose the right contractor. Safety is paramount. Your provider must be well-trained in all aspects of installation, including electrical wiring, refrigerant handling, combustion systems, and proper airflow through heating ducts. The installer must also understand home ventilation and exhaust systems to ensure your HVAC system is installed correctly and operates safely.
When selecting an HVAC company, consider the following:
- Licensed, Bonded, and Insured:Ensure your heating and cooling contractor meets the necessary education and experience requirements to be licensed in the industry.
- References: A professional HVAC company should have a list of recent customers you can contact to confirm their work was done promptly and to the customer’s satisfaction. Check out customer feedback on their Facebook page, Google Reviews, or testimonial pages.
- Rebates: Depending on the equipment you’re installing or upgrading, your project may qualify for rebates. Ask about any incentives available for your project.
- Maintenance Contracts: If you’re hiring an HVAC company for ongoing maintenance or new equipment installation, consider enrolling in their service contract program. These contracts ensure your HVAC system is regularly serviced by the company, providing added peace of mind.
