Frequently Asked Questions About HVAC Companies

What are the benefits of a programmable thermostat?

A programmable thermostat allows you to set different temperatures throughout the day, lowering your utility bills when you are not at home. Programmable thermostats can make managing your HVAC system easier and more efficient.

What are the signs that I need a new HVAC system?

Several signs indicate it might be time for a new HVAC system:

• Frequent Repairs: If your system requires repairs frequently, it may be more cost-effective to replace it.
• Age of System: HVAC systems typically last 15-20 years. If your system is nearing or beyond that age, it's likely less efficient and more prone to breakdowns.
• Increased Energy Bills: A significant rise in energy bills could indicate your system is losing efficiency and needs replacement.
• Uneven Temperatures: If some rooms are too hot or too cold, it could be a sign of an inefficient HVAC system.
• Poor Indoor Air Quality: If you're experiencing allergies, dust, or other indoor air quality issues, a new HVAC system with better filtration could help.
• Strange Noises or Smells: Unusual noises or foul odors emanating from your HVAC system could signal the need for a new HVAC system.

If you're unsure whether you need a new system, contact a trusted HVAC technician for an assessment.

How can I tell if my furnace filter needs changing?

Here are some signs your furnace filter needs changing (remember to change it every 1-3 months):

• Reduced Airflow: Noticeably weaker airflow from your vents.
• Dusty Vents: Dust accumulation around your vents.
• Increased Dust: More dust than usual in your home.
• Allergies or Respiratory Issues: Worsening allergy symptoms or respiratory problems.
• Higher Energy Bills: A dirty filter restricts airflow, forcing your furnace to work harder.
• Overheating: The system overheats due to restricted airflow.

Check your filter monthly and change it as needed to maintain good indoor air quality and HVAC system efficiency.

What are the signs my air conditioner needs refrigerant?

Low refrigerant levels can cause various problems with your air conditioner:

• Warm Air: The most noticeable sign is that the AC is blowing warm or not cool air.
• Ice Buildup: Ice may form on the AC unit.
• Increased Energy Bills: Your system has to work harder to cool, leading to higher energy consumption.
• Hissing or Bubbling Sounds: These sounds can indicate a refrigerant leak.

If you suspect low refrigerant, contact an AC repair specialist to diagnose the issue and recharge the system.
