Here are some common HVAC questions and their answers:

1. What does HVAC stand for?

   HVAC stands for Heating, Ventilation, and Air Conditioning.

2. How often should I change my HVAC air filter?

   It is generally recommended to change your HVAC air filter every 1-3 months, depending on factors like filter type, household dust levels, and pets.

3. How can I improve the energy efficiency of my HVAC system?

   You can improve energy efficiency by keeping your system well-maintained, sealing air leaks in your home, ensuring proper insulation, using a programmable thermostat, and scheduling regular HVAC maintenance.

4. How long should an HVAC system last?

   On average, an HVAC system can last between 15 to 20 years, but this can vary depending on the quality of the equipment, maintenance, and usage.

5. Why is my HVAC system not cooling/heating properly?

   There could be several reasons for this issue, such as a clogged air filter, refrigerant leaks, thermostat problems, blocked vents, or a malfunctioning compressor. It's best to have a professional HVAC technician diagnose and fix the problem.

6. How often should I have my HVAC system serviced?

   It is recommended to have your HVAC system serviced by a professional technician at least once a year. Ideally, it's best to schedule maintenance in the spring for cooling systems and in the fall for heating systems.

7. What size HVAC system do I need for my home?

   The size of the HVAC system you need depends on factors like the square footage of your home, insulation, number of windows, and climate. It's best to consult with an HVAC professional who can perform a load calculation to determine the appropriate size for your specific needs.

8. What is the difference between central air conditioning and a ductless mini-split system?

9. How can I improve indoor air quality in my home?

   To improve indoor air quality, you can regularly clean and vacuum your home, use air purifiers, control humidity levels, eliminate or reduce smoking indoors, and ensure proper ventilation.
