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 should I do if my AC breaks down?

If your AC breaks down, follow these steps::
  • Check for Obvious Issues: See if there are any easy fixes, like a clogged filter or power outage.
  • Turn Off the Unit: If you can't identify a quick fix, turn off your AC unit at the thermostat to prevent further damage.
  • Contact a Qualified HVAC Technician: Call a reputable HVAC repair company to diagnose the issue and provide repair options. If it's after hours, contact an emergency HVAC service.
  • Document the Problem: If possible, note any error codes or unusual behavior of the AC unit and take photos or videos of the problem to show the technician.
  • Prepare Questions: Make a list of questions for the technician to ensure you understand the problem, repair options, and costs.
Regular maintenance can help prevent many AC breakdowns. Get your system serviced regularly to maximize its lifespan and efficiency.

What is the average lifespan of a central air conditioner?

With proper maintenance, you can expect your central AC to last around 15-20 years. Several factors can affect its lifespan, including:
  • Regular Maintenance: Regularly scheduled maintenance can significantly extend the life of your AC.
  • Usage: Heavy use can shorten the lifespan.
  • Climate: AC units in hotter, more humid climates tend to have shorter lifespans.
  • Quality of Installation: A properly installed unit will perform better and last longer.
  • Quality of the Unit: Higher-quality AC units from reputable manufacturers are built to last longer.
If your AC is more than 15 years old, it's a good idea to consider your options.

What are the different types of air conditioners?

There are various types of air conditioners to choose from:
  • Central AC Units: These systems cool your entire home using ductwork to distribute conditioned air. Central air systems can provide excellent comfort.
  • Ductless Mini-Splits: Consisting of indoor and outdoor units that provide zoned cooling. Mini-splits can offer significant energy savings and greater control over your home's temperature.
  • Window AC Units: These are self-contained units designed to cool individual rooms. Window units are generally easy to install.
  • Portable AC Units: Similar to window units, but portable. They vent hot air through a window exhaust hose and are generally less efficient than other types of air conditioners.
  • Heat Pumps: These systems can both heat and cool. 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 for your specific requirements and budget.

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

A BTU (British Thermal Unit) measures how much heat an air conditioner can remove from a space. Correct BTU calculations are crucial for properly sizing an AC unit. A qualified HVAC technician will calculate the necessary BTUs for your space based on factors like:
  • 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.

What should I do if my AC breaks down?

In case of an AC breakdown, follow these steps::
  • Check for Obvious Issues: Look for simple problems, like a tripped circuit breaker or a dirty air filter.
  • Turn Off the Unit: If you can't identify a quick fix, turn off your AC unit to avoid additional problems.
  • Contact a Qualified HVAC Technician: Call a reputable HVAC repair company to diagnose the issue and provide repair options. If it's after hours, contact an emergency HVAC service.
  • Document the Problem: If possible, note any error codes or unusual behavior of the AC unit and take photos or videos of the problem to show the technician.
  • Prepare Questions: Make a list of questions for the technician to ensure you understand the problem, repair options, and costs.
Regular maintenance can help prevent many AC breakdowns. Consider scheduling an annual tune-up with an HVAC contractor to keep your AC unit in top condition and avoid future breakdowns.

What is the average lifespan of a central air conditioner?

A central air conditioner typically lasts between 15 and 20 years. Several factors can affect its lifespan, including:
  • Regular Maintenance: Regularly scheduled maintenance can significantly extend the life of your AC.
  • Usage: The more you run your AC unit, the faster it will wear out.
  • Climate: AC units in harsh environments tend to have shorter lifespans.
  • Quality of Installation: A properly installed unit will perform better and last longer.
  • Quality of the Unit: More durable units generally have a longer lifespan.
If your AC is more than 15 years old, it's a good idea to start planning for a replacement.

What are the different types of air conditioners?

There are various types of air conditioners to choose from:
  • Central AC Units: Ideal for whole-home cooling 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 that provide zoned cooling. They're quiet, efficient, and ideal for room additions or supplemental cooling.
  • Window AC Units: A good option for smaller spaces or apartments. They're relatively inexpensive but can be noisy and less efficient than other options.
  • Portable AC Units: These units can be moved easily and offer a flexible option for supplemental cooling in various rooms. They vent hot air through a window exhaust hose and are generally less efficient than other types of air conditioners.
  • Heat Pumps: These systems can both heat and cool. They offer excellent energy efficiency by transferring heat instead of generating it directly.
  • Geothermal Heat Pumps: Geothermal heat pumps use the stable temperature of the earth to heat and cool your home. They are very efficient, but the initial installation cost can be higher due to the need for ground loops.
A qualified HVAC technician can help you choose the right air conditioner for your home and recommend the best AC unit for your specific requirements and budget.
