Is your old AC making weird sounds and not working properly? Don’t worry; we have a complete guide to AC replacement to help you find out all about the steps you need to take next. 

The step to replace your air conditioning system shouldn’t be taken lightly. It’s a significant decision that hinges on several factors – the age of your equipment, the frequency and cost of repairs, your energy bills, and issues related to operational efficiency, noise levels, temperature inconsistency, and indoor air quality. 

As modern air conditioners boast larger sizes and quieter operations compared to their predecessors, they often necessitate adjustments to their installation spots. This article will help you make informed decisions about replacing your air conditioning unit.

Recognizing the Right Time for AC Replacement

Recognizing the right time to replace your air conditioning system is essential for keeping your home comfortable and energy-efficient. Let’s go over some of the key signs that indicate it might be time to consider changing your air conditioner:

Age and Malfunction of Your AC

If your air conditioning system is over 15 years old, its operational lifespan is likely coming to an end. Decreased performance, such as not cooling effectively or cooling unevenly, can indicate it’s time for a replacement. 

If your air conditioner doesn’t respond well to the thermostat or if certain areas in your home are cooler than others, it might be a sign of issues with the thermostat or ductwork.

Frequent Repairs and Rising Costs

Frequent repairs, unusual sounds, moisture around the unit, and rising energy bills are signs of potential problems with your air conditioning system. 

When deciding between repair and replacement, consider the long-term sustainability and costs. When the cost of repairing and operating an old AC unit is greater than the cost of installing and operating a new AC over a multi-year period, it’s time to replace the old AC.

Refrigerant Type 

Post-2010, new equipment cannot be manufactured with R-22 refrigerant (Freon). R-410A (Puron) is the standard now. If your AC requires R-22 refrigerant, consider replacing it, as R-22 is being phased out and can be expensive to replace due to decreased production.

Thanks to the above-listed factors, you can make an informed decision about when to replace your air conditioning unit, ensuring that your home remains comfortable and your energy bills stay manageable. 

The Importance of Professional Installation

Embarking on an air conditioner replacement journey can be a complex process, but having a professional team for your AC installation on your side is a cornerstone for ensuring the efficiency, safety, and longevity of your new system. 

Here’s why opting for professional installation within your AC replacement is crucial:

Expert Installation and System Calibration

Before the actual installation, certified technicians meticulously assess and modify essential components such as low and high-voltage wiring, refrigerant piping, electrical breakers, ductwork, and the condenser pad. 

The installation process includes securely attaching ductwork to the air handler, brazing refrigerant lines, reconnecting electricity, and ensuring the drain system is properly reattached. These steps demand a high level of precision only professional technicians can provide.

A comprehensive startup assessment follows the installation. Technicians check refrigerant levels, airflow, supply air temperature, and drain function to guarantee your air conditioning system operates at peak efficiency from day one.

Safety, Warranty, and Efficiency

Professional installers are well-versed in local safety codes and regulations, significantly reducing the risk of electrical fires or other hazards. Their expertise ensures your AC installation adheres to all safety standards.

Plenty of manufacturers prerequisite professional installation as a condition of the warranty they give you. This stipulation underscores the importance of having your AC unit installed by certified technicians to maintain its warranty.

Proper installation also prevents air quality issues by ensuring ductwork is leak-free, keeping pollutants and allergens out of your living space.

Long-term Benefits and Professional Accountability

Correct installation techniques extend the system’s lifespan and prevent costly future repairs. This includes using the right mounting hardware and ensuring all electrical connections are secure. Hiring a professional team not only protects against installation errors but also ensures a faster installation process. 

Incorporating professional AC installation into your air conditioning replacement project is a necessity for ensuring your new system functions efficiently, safely, and effectively for years to come. 

Maintenance Tips for Your New AC

Maintaining your new air conditioning system is paramount to ensuring its efficiency and longevity and keeping your home comfortable throughout the warmer months. A well-maintained AC unit also means fewer calls for AC repair.

Regular Inspection and Cleaning

You should clean your AC filter every month. A clean filter improves air quality and enhances the efficiency of your air conditioning system, preventing it from working harder than necessary.

Inspect and clean the evaporator and condenser coils at least once a year to maintain thermal efficiency. Dirt and debris can insulate coils, reducing their ability to absorb heat. Ensure the condensate drain is clear of blockages. A clogged drain can cause water leakage, affecting your system’s efficiency and potentially causing water damage.

Preventative Measures

For central AC systems, maintain a 24-inch clear space around the air compressor and condenser units. This ensures proper airflow and system performance. 

Schedule a yearly cleaning and inspection with a licensed HVAC contractor before the cooling season starts. This service should include cleaning coils, adjusting and replacing fan belts, lubricating motors and bearings, and checking refrigerant levels and pressures.

System Optimization

Ensure the outdoor condenser unit is level. An unlevel condenser can cause premature wear and reduce the efficiency of your air conditioning system. Have a professional check for proper refrigerant levels and leaks. Incorrect refrigerant levels can reduce the efficiency of your AC unit, increasing energy costs and the need for AC repair. Regularly vacuum and wipe down vent covers to remove dust and obstructions, ensuring proper airflow. 

The Replacement Process

Consulting with local HVAC technicians is the first crucial step when replacing your air conditioning unit. These professionals will help you weigh the pros and cons of repairing versus replacing your HVAC system. Here’s how the replacement process goes:

  • Technicians will ensure all power sources to the old system are safely disconnected.
  • Parts, such as the air handler, condenser, and any associated ductwork, are carefully removed.
  • Old parts are disposed of responsibly, with recyclable materials being separated.
  • The area is inspected for any issues affecting the new installation, such as space constraints or the need for ductwork modifications.
  • The site is thoroughly cleaned to ensure a clean environment for the new system.
  • The new air handler and condenser are placed in their respective locations, ensuring they’re level and secure.
  • Electrical and refrigerant lines are connected, following strict safety and efficiency guidelines.
  • Once installed, the system is tested for functionality, including airflow and refrigerant levels.

Throughout this procedure, it’s essential to remember that choosing the right professionals for your AC installation is vital. Certified technicians not only ensure a seamless installation process but also uphold the warranty of your new air conditioning system.
