Frequently Asked Questions About HVAC Companies

What are the different types of HVAC systems?

Several types of HVAC systems are available for residential and commercial buildings:

• Split Systems: The most common type, consisting of an outdoor unit (condenser/compressor) and an indoor unit (air handler/furnace).
• Heat Pumps: Provide both heating and cooling by transferring heat between indoor and outdoor air.
• Ductless Mini-Splits: Ideal for homes without existing ductwork or for adding heating and cooling to specific zones.
• Packaged Units: A single unit that contains all the system's components.
• Geothermal Heat Pumps: Use the earth's stable temperature to provide highly efficient heating and cooling.

An HVAC professional can help determine the best type of system for your needs and budget.

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 refrigerant lines or evaporator coil.
• 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.

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 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.
