Frequently Asked Questions About HVAC Companies

Find answers to common questions about HVAC services, finding contractors, and getting the best heating and cooling solutions for your needs.

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 keep your system running efficiently.

What is the difference between an AC unit and a heat pump?

While both air conditioners and heat pumps provide cooling, they differ in how they generate heat. An AC unit cools your home by extracting heat and transferring it outside. It uses a separate furnace or heating system for heating in colder months. A heat pump, however, can both cool and heat. In cooling mode, it functions like an AC, extracting heat from indoor air and releasing it outdoors. In heating mode, it reverses this process, extracting heat from the outside air (even in cold temperatures) and transferring it inside. This makes heat pumps more energy-efficient for heating than traditional electric resistance heating, especially in mild to moderately cold climates.

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 lukewarm 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 HVAC technician to fix the leak and add refrigerant.

Should I repair or replace my old furnace?

Deciding between repairing or replacing your furnace depends on
  • Age: Furnaces typically last 15-20 years. If yours is significantly older, replacement is usually the better overall choice.
  • Frequency and Cost of Repairs: If you've been having repeated repairs, replacing the furnace might be more cost-effective in the long run.
  • Energy Efficiency: Newer furnaces are significantly more energy-efficient, which can lead to lower energy bills.
  • Safety Concerns: Older furnaces might have safety issues, such as carbon monoxide leaks. A new furnace offers enhanced safety features.
Consult with a trusted HVAC professional to assess your furnace and get recommendations.
