Frequently Asked Questions About HVAC Companies

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 not cool 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 may suggest a refrigerant leak.

If you suspect low refrigerant, contact an HVAC technician 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.

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 often the better long-term choice.
• Frequency and Cost of Repairs: If you've been having frequent or expensive 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 reputable HVAC professional to assess your furnace and get recommendations.

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.
