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.

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 regular maintenance should I do on my HVAC system?

You can perform some simple maintenance tasks yourself to keep your HVAC system running smoothly:
  • Change Air Filters: Change or clean your air filters every 1-3 months. Dirty air filters restrict airflow and decrease system efficiency.
  • Clear Debris: Keep the area around your outdoor unit clear of debris, leaves, and snow.
  • Check Thermostat Settings: Make sure your thermostat is set to the desired temperature and is functioning correctly.
For more complex maintenance, like cleaning coils or checking refrigerant levels, contact a qualified HVAC technician. Schedule annual or biannual maintenance with a reputable HVAC contractor.

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 often, 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 might mean 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 ductwork problems or an undersized/aging 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.

What should I ask an HVAC technician during a service call?

When an HVAC technician comes for a service visit, ask these important questions:
  • What is the source of the problem? Get a clear explanation of the issue and what caused it.
  • What are my repair options? Discuss different repair solutions, if applicable, and their associated costs.
  • Are there any preventative measures I can take? Find out if there are steps you can take to prevent future problems.
  • Do you recommend a repair or replacement? If repairs are extensive or the system is old, consider replacement.
  • What are the warranties on parts and labor? Understand the warranties before agreeing to any repairs.
  • Do you have any customer reviews or testimonials I can check? Reputable HVAC technicians are often happy to provide references or direct you to customer reviews.
Asking these questions can help you make an informed decision and feel confident in the HVAC technician's expertise and recommendations.
