Frequently Asked Questions About HVAC Companies

What are the most common HVAC problems?

Common HVAC problems include:

• AC not cooling: Refrigerant leaks, compressor issues, or thermostat problems.
• Furnace not heating: Pilot light or ignition control issues, blower motor problems, or clogged filters.
• Uneven temperatures: Ductwork leaks, inadequate insulation, or faulty thermostats.
• Poor air quality: Dirty air filters, mold growth in ductwork, or inadequate ventilation.
• Strange noises: Unusual sounds from the system can indicate a variety of problems with different components.
• High energy bills: Inefficient systems, ductwork leaks, or improper thermostat settings.

If you're experiencing any of these issues, contact a qualified HVAC technician for diagnosis and repair.

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.

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 is a ductless mini-split system?

A ductless mini-split system is a type of HVAC system that doesn't require ductwork. It consists of an outdoor unit (compressor/condenser) and one or more indoor units (air handlers) connected by refrigerant lines and electrical wiring. Each indoor unit cools or heats a specific zone or room, providing individual temperature control. Ductless mini-splits are more energy-efficient than traditional ducted systems and are a good option for homes where adding ductwork is impractical.
