1. How often should I service my HVAC system?

Most HVAC systems should be serviced twice a year—once in the spring for cooling and once in the fall for heating. Regular maintenance helps prevent breakdowns, improves efficiency, and extends the life of your system.

2. How often should I change my air filter?

Usually every 1–3 months, depending on:

• Pets in the home
• Allergies
• Filter type
• System usage

Dirty filters reduce airflow and can increase energy costs.

3. Why is my energy bill suddenly so high?

Common reasons include:

• Dirty air filters
• Aging or inefficient equipment
• Poor insulation or air leaks
• Extreme outdoor temperatures

A professional inspection can pinpoint the cause.

4. How long does an HVAC system usually last?

• Furnaces: 15–20 years
• Air conditioners: 10–15 years
• Heat pumps: 10–15 years

Regular maintenance can help systems last longer.

5. Why is my system blowing air but not heating or cooling properly?

This could be caused by:

• Low refrigerant
• Dirty coils or filters
• Thermostat issues
• Mechanical or electrical problems

A technician can diagnose the issue quickly.

6. What are signs I need HVAC repair?

• Strange noises or smells
• Uneven temperatures
• Weak airflow
• Frequent cycling on/off
• Rising energy bills

If you notice any of these, it’s best to call before the problem gets worse.
