Many homeowners wonder: Can I just replace my outside AC unit? Depending on the age and quality of the unit, the answer may be yes. However, it is important to maintain the unit regularly to ensure it’s working as effectively as possible. The US Department of Energy recommends replacing the HVAC system every 10 to 15 years, but a unit can last much longer if its maintenance is done by professionals like air conditioning services. In addition to cleaning and maintaining the unit, it should also be professionally maintained every six months, usually before the start of the summer or winter season. However, if you do not perform maintenance, it could be time for a replacement.
While it is tempting to replace only the outdoor unit, it’s best to consider the SEER rating of your new HVAC system before making a decision. SEER stands for Seasonal Energy Efficiency Ratio and is the measure of an AC’s efficiency. It is recommended that your indoor and outdoor units have the same SEER rating, since replacing one with another can cause the rest of the system to be mismatched.
While replacing your outdoor AC unit can save you money in the long run, you’re probably not getting the most out of it. A new unit with a higher SEER rating will increase the efficiency of your entire AC system. A new system with a lower SEER rating will cost you more in energy. You can save money by hiring an HVAC professional to replace the entire system, but you must be aware that it may not last as long.
Air Conditioning System
If your air conditioning system is three to five years old, the manufacturer may still provide you with a replacement outdoor unit at no charge. If this is the case, it’s best to consult a technician to determine the best solution for your home. Some air conditioners have a limited warranty, so you’ll need to make sure the replacement is compatible. Then, it’s time to look for a new HVAC technician.
What should I do if the indoor and outdoor units don’t match? If you have an older air conditioning system, you’ll need a new indoor unit, as the old one is not designed for it. Ideally, you should replace both units. It’s also worth noting that the manufacturer’s warranty will remain valid as long as the units match properly. If you’re replacing both indoor and outdoor units, you can rest assured that your indoor unit is compatible as well.
Upgrading Your Indoor Air Conditioner
If you’re concerned about the environment, you may want to consider upgrading your indoor air conditioner. While most modern units use environmentally-friendly R-410A refrigerant, older units still use hazardous R-22, which destroys the ozone layer. In addition to saving money on energy bills, upgrading your HVAC system will improve safety and efficiency. Just be sure to check the compatibility of indoor and outdoor units before making a decision.
