Frequently Asked Questions about AC Replacement

Find answers to common questions about replacing your air conditioner. Get informed and make the best decision for your home or business.

What are the different types of air conditioners?

There are several options of air conditioners to choose from:
  • Central AC Units: These systems cool your entire home using ductwork to circulate cool air. They're energy-efficient and provide consistent cooling throughout your home.
  • Ductless Mini-Splits: Consisting of indoor and outdoor units connected by refrigerant lines. They're quiet, efficient, and ideal for targeted area cooling.
  • Window AC Units: These are self-contained units designed to cool individual rooms. Window units are generally easy to install.
  • Portable AC Units: These units can be moved easily and offer a flexible option for supplemental cooling in various rooms. Consider portability when access to windows might be difficult.
  • Heat Pumps: These systems can both provide year-round climate control. Heat pumps are energy-efficient, especially in mild to moderate climates.
  • Geothermal Heat Pumps: Geothermal heat pumps use the stable temperature of the earth to heat and cool your home. Though they require a significant upfront investment, the long-term energy savings are substantial.
A qualified HVAC technician can assess your cooling needs and recommend the best AC unit to match your home and your preferences.

How do I calculate the right BTU for my AC unit?

A BTU (British Thermal Unit) measures cooling capacity from a space. Choosing the right BTU rating is important for optimal performance and energy efficiency. The required BTUs depend on several factors, including:
  • Room size (square footage)
  • Climate
  • Insulation levels
  • Window size and type
  • Number of occupants
An accurate load calculation ensures you don't buy an undersized or oversized unit.

How do I clean my AC unit?

Regular cleaning of your AC unit can improve its efficiency and extend its lifespan. Follow these steps for cleaning:
  • Turn off the power: Before cleaning, disconnect the power to your AC unit at the circuit breaker.
  • Clean the outdoor unit: Clear away any debris, such as leaves, grass, and dirt, from around the unit. Use a garden hose to rinse the condenser coils and fins.
  • Clean the indoor unit: Remove the access panel to the air handler and clean or replace the air filter. Remove any visible dust and clean the drip pan to prevent mold growth.
For a more thorough cleaning and inspection, contact a qualified HVAC technician.

  • Central AC Units: These systems cool your entire home using ductwork to distribute conditioned air. They're energy-efficient and provide consistent cooling throughout your home.
  • Ductless Mini-Splits: Consisting of indoor and outdoor units connected by refrigerant lines. They're quiet, efficient, and ideal for targeted area cooling.
  • Window AC Units: A good option for smaller spaces or apartments. Window units are generally easy to install.
  • Portable AC Units: Similar to window units, but portable. Consider portability when access to windows might be difficult.
  • Heat Pumps: These systems can both provide year-round climate control. Heat pumps are energy-efficient, especially in mild to moderate climates.
  • Geothermal Heat Pumps: Geothermal heat pumps use ground temperature to heat and cool your home. They are highly efficient, but the initial installation cost can be higher due to the need for ground loops.
