Safe checks to try
Only try steps you are comfortable with — stop if anything feels unsafe.
Inspect your air filter for dirt and replace it if visibly clogged, typically every 1-3 months depending on usage.
Stop if: No change in airflow or temperature after replacement.
Verify all supply and return vents are open and unobstructed by furniture, curtains, or other items.
Stop if: Vents are clear but airflow remains weak or uneven.
Check your thermostat settings and battery, ensuring it's set to 'auto' and the desired temperature.
Stop if: Thermostat appears unresponsive or displays error codes.
Look for any visible ice accumulation on the outdoor unit or refrigerant lines near the indoor unit. If found, turn off the system immediately.
Stop if: Ice is present, as this suggests a serious issue requiring professional attention.
Ensure all windows and doors are properly sealed to prevent conditioned air from escaping or outside air from entering.
Stop if: Drafts are noticeable even after sealing efforts.
When to call a professional
- After performing basic safe checks, issues persist or worsen.
- You notice ice on refrigerant lines or the outdoor unit.
- The system makes unusual noises or emits strange odors.
- Your system is older, possibly using R-22 refrigerant.
- Repeated circuit breaker trips occur when the HVAC runs.
What to ask if you hire
- 1.Can you provide a detailed diagnosis of the temperature imbalance?
- 2.What are the estimated costs for parts and labor for the recommended repairs?
- 3.Will any proposed work require local permits, and who is responsible for obtaining them?
- 4.Can you explain the warranty on any new parts or services offered?
- 5.What manufacturer documentation supports the recommended solutions or replacements?
- 6.Are there any energy efficiency upgrades you'd suggest for my Granbury home?
What to look up next
- Ensure the scope of work is clearly defined and matches the diagnosis.
- Verify all costs, including labor, parts, and any potential permit fees, are itemized.
- Confirm the contractor is licensed and insured for HVAC work in Hood County.
