5 Reasons to Replace Indoor and Outdoor HVAC Units Together

If your HVAC system consists of an indoor and outdoor unit, it’s possible to have them replaced separately, should one become damaged beyond repair. But is this a good idea? In this blog, heating and air conditioning company Countryside explains the benefits of replacing both units at the same time when just one unit  breaks down.


1. Better Performance — You’re more likely to get better long-term performance out of a matched system, since the units are designed to work with each other. While it is possible to install a new indoor unit with an existing outdoor unit (or vice versa), it’s generally not recommended. Manufacturers design indoor and outdoor units as parts of a whole unit, and while new units are backwards-compatible, they won’t be as efficient, and may actually cost more to keep running over time.Efficiency Ratings

2. Are Based on Matched Systems — Heat pumps are essentially air conditioning units equipped with a reversing valve. This is why you’ll see two ratings for one system: SEER (Seasonal Energy Efficiency Ratio) for air conditioning, and HSPF (Heating Seasonal Performance Factor) for heating. These ratings are based on paired units, therefore, you can’t expect to get the same performance and savings when the units aren’t matched.

3. Differences In Technology — If the manufacturing dates of units are several years apart, there will be significant differences between factors such as filtering, noise levels and energy usage. Using an old unit with a new one can actually impede the new unit’s performance. In addition to compromising long-term performance, you could also miss out on energy savings.

4. You Might Pay for Installation Costs Twice — If one of the two units breaks down due to age, the second one will likely follow shortly after. Thus you could end up paying for installation on two separate occasions.New Units

5. Mean New Warranties — Purchasing new HVAC equipment means you get full coverage from the manufacturer, along with the service guarantees that come with it. These warranties are generally much better compared to the sum of indoor and outdoor units installed separately.Call Countryside for Your Heating and Cooling NeedsCountryside is your leading provider of air conditioner sales, repair  and maintenance services.
