When your air conditioner can no longer keep up with your cooling needs, it’s time for a new AC installation. But what exactly does that involve? If you’ve never had to replace your air conditioner, the process can seem confusing. That’s why our team at Moncrief Heating & Air Conditioning is here to simplify and explain what to expect from an AC installation. Understanding the AC installation process can help you make informed decisions, know what to expect on installation day, and ensure your new system delivers reliable comfort for years to come.
Why Hire a Professional for an AC Installation
Some homeowners may be tempted by the thought of taking a DIY approach to their air conditioner installation as a way to save money. However, when an air conditioning installation in Atlanta goes wrong, it can put a lot at risk. From damaging the unit to injuring yourself, the consequences of poorly installing AC on your own can be immense. Installing an air conditioner requires immense knowledge of how these complex systems work, as well as dealing with refrigerants and electrical connections that can be dangerous if handled incorrectly. Also, hiring a professional ensures that the unit is properly sized for your home and installed correctly. An AC that has not been installed or sized correctly can drive up energy costs and run into frequent issues that require repairs.
How To Choose the Right AC Size
One of the most important steps in any AC installation guide is selecting the correct system size. Many people assume a larger air conditioner will cool their home better, but this is actually not the case. An oversized system can cycle on and off too frequently, leading to uneven temperatures, excess humidity, and unnecessary wear. On the other hand, an air conditioner that is too small for your home may struggle to keep your home comfortable during Atlanta’s hottest summer days.
Our professional HVAC installation team can determine the right size using a load calculation, often called a Manual J calculation. This evaluates factors such as:
- Your home’s square footage
- Insulation levels
- Window placement and sun exposure
- Ceiling height
- Number of occupants
- Local climate conditions
Understanding Efficiency (SEER2)
When comparing new air conditioners, you’ll likely see efficiency ratings listed as SEER2. SEER2 (Seasonal Energy Efficiency Ratio 2) measures how efficiently an air conditioner cools your home over an entire cooling season.
Higher-efficiency systems typically use less electricity while maintaining the same level of comfort. Although every home is different, choosing an efficient system can help reduce energy consumption during Atlanta’s long cooling season.
We can explain which efficiency level makes the most sense for your home and budget rather than simply recommending the highest-rated system.
What to Expect on Installation Day
If you’ve never replaced an air conditioner before, it’s natural to wonder what the AC installation process involves. Fortunately, professional installation is designed to be straightforward and minimally disruptive.
A typical installation includes:
- Confirming the equipment and reviewing the installation plan.
- Safely disconnecting and removing the old system.
- Installing the new indoor and outdoor equipment.
- Making electrical, refrigerant, and ductwork connections as needed.
- Testing refrigerant levels, airflow, thermostat operation, and overall system performance.
- Reviewing the completed installation with you and answering any questions about operating your new system.
Before your appointment, homeowners can help by clearing a path to the indoor and outdoor equipment and ensuring your technicians have easy access to the work area. It’s also a great opportunity to ask questions about filter replacement, maintenance schedules, and how your new thermostat operates.
FAQs About AC Installations
Choosing a new air conditioner often comes with plenty of questions. Here are answers to some of the most common questions homeowners have before scheduling a replacement.
How long does AC installation take?
Most residential AC installations can be completed in a single day, although larger or more complex projects may take longer. Factors such as ductwork modifications, electrical upgrades, or replacing both the indoor and outdoor equipment can affect the timeline. Your installer will provide an estimated schedule before work begins.
What size AC unit do I need for my home?
The right size depends on much more than your home’s square footage. HVAC professionals evaluate insulation, windows, ceiling heights, layout, and other factors to calculate the appropriate capacity. A properly sized system delivers better comfort, improved efficiency, and more consistent cooling throughout your home.
How do I know if it's time to replace my AC?
If your air conditioner is 10 to 15 years old, requires frequent repairs, struggles to cool your home evenly, or causes steadily increasing energy bills, replacement may be the better long-term option. Our team can help determine whether repairs are still worthwhile or whether installing a new, energy-efficient system makes more sense. We always provide honest recommendations and don’t try to upsell you on services that you do not need.
