If your HVAC system is more than a decade old, it will have to be replaced in the next few years. On the other hand, if you have a newer HVAC system, you want to ensure it keeps on running right by scheduling its annual maintenance. Either way, you will need to hire an HVAC contractor. Here are some of the top things to look for to choose the right HVAC contractor:

• Licensing and experience

An HVAC system is the most expensive system most people have at home and you want to make sure that whoever works on it has the proper training. Always check the license of an HVAC contractor because they can only get it after they have worked for a number of years. They should also have been around in the industry for a while and have developed a good reputation for their business. Unlicensed contractors should be avoided at all costs if you don’t to waste your money.

• Reference and referrals

Before choosing a contractor for HVAC maintenance, you should ask them to provide references and referrals. Call these people up and ask them if the jobs were done on time and within the specified budget. Make sure the contractor did a clean installation and respected the property of the homeowner. When you want referrals, you can talk to your friends, neighbors and co-workers for some good names.

• Home evaluation

Never hire an HVAC contractor that’s willing to give you a quote over the telephone. Bear in mind that any reputable contractor will never make this mistake. They will always come for a home evaluation first, assess your needs and then give you a quote. They will provide a written, itemized estimate that will enable you to compare costs, energy efficiency and warranties amongst the proposals.
