Top questions to ask before hiring an hvac company

What type of insurance do you have? Heating, ventilation and air conditioning (HVAC) professionals work on a variety of mechanical areas of the home. You'll want to ask specific questions regarding professional training and licensing, as well as what types of insurance they have (for example, mold, air pollution or worker's compensation). It's fair to ask for the dollar amounts they are covered and a quality professional will show you verification of coverage.

HVAC professionals attend to a home's thermal needs as well as air quality. Because of the technical aspects of HVAC work, find out the scope of work your professional can perform. You may only need your heating unit serviced however, if this professional also specializes in energy efficiency, mold assessment, or offer ways for you to save on energy costs, you may want to hire them for future projects. Because some equipment is gas-powered, your professional should be able to answer questions about installing gas lines and permitting.

Ask about guarantees on labor or warranties on parts for your HVAC project. It's common to have a time limitation on parts and equipment. Save any paperwork related to your project so you can refer back to instruction manuals or serial numbers.

When working with a heating and cooling professional, ask if their company offers pricing incentives to encourage you to hire them on a regular basis. It's common to have your equipment inspected and serviced at least once a year. Your HVAC company may also offer special pricing on filters, ventilation cleaning or energy assessments.

Regardless of the scope of your project, find out what you need to do to prepare your home for their visit. For example, the HVAC professional will need access to the areas in question and may need access to other mechanical or ventilation points. Make sure pets and children are kept out of the way. Ask if your project will involve removing dry wall or making any other structural changes – you may need to hire a professional drywall contractor to patch up HVAC work. If you are adding a unit that may contribute to carbon monoxide within the home, find out if you need to purchase a carbon monoxide detector.
