HVAC systems regulate the temperature, humidity and air quality in residential structures such as single family homes and apartment buildings; commercial and public buildings like skyscrapers, hospitals and restaurants; automobiles, boats, trains, airplanes and submarines; and many other kinds of man-made environments. HVAC contractors install, repair and maintain heating, ventilation and air conditioning equipment. They are also knowledgeable about indoor air quality and can recommend and implement solutions to improve it.
HVAC installation tasks can include surveying/inspecting an existing system and taking measurements to ensure that a new system is the proper size for the home; de-installing the old unit, being careful not to disturb comfort for occupants; installing the new unit; and connecting the new units, including wiring, tubing, pipes or electrical supply lines. Some installations require the fabrication of sheet metal, which adds to the cost.
When it comes to repairs, HVAC technicians can troubleshoot and resolve a wide range of problems with heating, cooling and air ventilation systems. They can also repair and replace ductwork, if necessary. In addition, they can diagnose problems by using tools like pressure gauges, thermometers and airflow meters.
When selecting an HVAC contractor, look for one with certifications and industry affiliations. They should also be punctual and courteous, and willing to explain their services and pricing. They should also be familiar with EPA Section 608 Technician Certification requirements, as well as state licensing and certification requirements for working on refrigerants. If your property is located in a remote or challenging-to-reach area, an HVAC contractor may charge more for travel time and fuel expenses. Hvac services
