What is HVAC?
HVAC professionals install, maintain, and repair heating, ventilation, and air conditioning systems that regulate indoor climate and air quality. Their expertise covers central air conditioning, heat pumps, furnaces, boilers, ductwork design and installation, mini-split ductless systems, commercial rooftop units, radiant floor heating, air quality testing, filtration systems, humidification and dehumidification, zoning systems, and smart thermostat integration. HVAC technicians perform seasonal maintenance including refrigerant level checks, coil cleaning, filter replacement, combustion analysis, and efficiency testing. They also handle emergency repairs for no-heat and no-cooling situations. Modern HVAC work increasingly involves energy-efficient system design, heat pump conversions from fossil fuel systems, and integration with building automation systems for optimal comfort and energy savings.
Licensing and Regulations
HVAC technicians need EPA Section 608 certification for refrigerant handling. Most states also require HVAC contractor licenses involving trade exams, proof of experience, insurance, and bonding.

How to Hire the Right HVAC Contractor
Schedule seasonal maintenance every spring (cooling) and fall (heating) to prevent breakdowns
Get a Manual J load calculation before installing a new system to ensure proper sizing
Ask about energy efficiency ratings (SEER2 for cooling, AFUE for heating)
Verify the technician holds EPA Section 608 certification for refrigerant handling
Request information about available rebates and tax credits for energy-efficient upgrades
Frequently Asked Questions
How often should HVAC systems be serviced?▼
HVAC systems should be professionally serviced twice per year: once in the spring before cooling season and once in the fall before heating season. Regular maintenance extends equipment life, maintains efficiency, identifies developing problems, and preserves manufacturer warranty coverage.
How long does a typical HVAC system last?▼
A well-maintained central air conditioning system typically lasts 15 to 20 years. Furnaces last 15 to 25 years. Heat pumps typically last 12 to 17 years. Boilers can last 20 to 30 years with proper maintenance. Actual lifespan depends on usage patterns, maintenance history, and installation quality.
What size HVAC system do I need?▼
System sizing requires a professional Manual J load calculation that considers your home's square footage, insulation levels, window specifications, climate zone, orientation, occupancy, and other factors. An oversized system wastes energy and creates humidity problems; an undersized system cannot maintain comfort.
What is a SEER rating?▼
SEER (Seasonal Energy Efficiency Ratio) measures the cooling efficiency of an air conditioner or heat pump. Higher SEER ratings indicate greater efficiency. The current federal minimum is 14 to 15 SEER depending on region. High-efficiency systems range from 18 to 26 SEER. The newer SEER2 standard uses updated testing conditions.
Should I repair or replace my HVAC system?▼
Consider replacing when repair costs exceed 50 percent of the value of a new system, when the system is more than 15 years old and requiring frequent repairs, when energy bills are consistently rising despite maintenance, or when the system uses R-22 refrigerant which is no longer manufactured.
