Before hiring an HVAC service provider, ask about licensing, liability insurance and bonding.
The heating and cooling system is one of the most complex systems that can be found in a home. It’s essential that the HVAC service provider you hire is well-trained to deal with the inherent safety issues in heating systems — electricity, natural gas, oil — or cooling units that use toxic refrigerants such as Freon.
It might seem OK to have a friend, or family member perform essential service or maintenance, but having a licensed professional do it will benefit you because:
1. A qualified technician can often find and address small problems with A/C units through a regular inspection that, left unnoticed, could grow into larger, more expensive issues.
2. A properly performed tune up can help reduce your monthly energy bill by up to 15 percent and help prevent earlier-than-normal breakdowns.
3. And, since an ac system can lose 5% of its efficiency per year, a professional can help minimize the loss in efficiency.
