Frequently Asked Questions About HVAC Companies

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 type of HVAC system is best for my home?

The best HVAC system for your home depends on several factors, including your:

• Climate: Heat pumps are generally more efficient in moderate climates, while furnaces are better for colder regions.
• Budget: The upfront cost of different systems can vary significantly.
• Energy Efficiency Goals: Higher-efficiency systems are usually more expensive upfront but result in lower energy bills over time.
• Home Size and Layout: The square footage and layout of your home affect the system's capacity and ductwork requirements.
• Existing Ductwork: If you have existing ductwork, you'll need a system compatible with it.

A qualified HVAC contractor can assess your needs and recommend the most suitable heating and cooling system for your property.

What is the best temperature to set my thermostat in summer?

The best temperature to set your thermostat in summer depends on your personal preferences and how much you’re willing to spend on energy costs. A general recommendation is to set your thermostat to 78°F (26°C) when you're home and awake. Consider a programmable thermostat that allows you to automatically adjust the temperature based on your schedule.

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.
