To repair or to replace? That is the question. When it comes to the HVAC system, it can be quite an investment, so the thought of replacing the whole system is often daunting. Nonetheless, repairs aren’t always warranted, and sometimes it’s worth it to bite the bullet for an HVAC upgrade, as repairs will be more expensive in the long run. Let’s take a more in depth look and compare when it’s best to repair and when it’s best to replace. 

Critical Considerations for HVAC Systems in NY & NJ

First and foremost, how old is the system? Simply speaking, if the system is still relatively new and under warranty, repairing is a smarter choice. On the other hand, if the system has served its time (typically over 10-15 years old), repairs can end up being more costly in the long run. In the world of HVAC, there exists a $5000 rule, where if the equipment age multiplied by the repair cost is greater than $5000, it’s probably best to replace the system than to perform the needed repairs. For example, if your unit is 7 years old, and repair costs are $2000 (7×2000 = 14,000) it’s best to replace the system, but if your unit is only 2 years old with a $2000 repair bill (2×2000=4000), it’s worth it to repair. 

Other things to note when it comes to repair or replacing:

Frequency of Repairs

Are you having to repair your system every other month? It’s important to take into account accumulating repair costs. 

Irregular Temperature Regulation

If your system is cycling without stopping, or if warm air is blowing when it shouldn’t be, it’s definitely a sign that your system should be looked at, as causes can range from simple to not so simple fixes.

Noises

Yes, HVAC systems produce a little noise, but generally speaking they tend to be rather quiet, so anything out of the ordinary should be looked at.

Leaking Refrigerant

Depending on the severity and the type of refrigerant that is leaking, this can be a rather costly issue. For example, R22 refrigerant (which is commonly used in older systems), is a hydrochlorofluorocarbon and has been linked to ozone depletion, because of this it’s being mandatorily phased out by the EPA, and becoming harder and harder to obtain. Hence the sky high prices for this type of refrigerant refill. Newer HVAC systems use refrigerants with lower global warming potential, so if your system uses R22, you may want to think about swapping to a greener, more efficient HVAC option. 

Warranty

Is the warranty still valid? Warranty periods can range from 5 to 10 years, and if the warranty is expired, repairing may not be the best option. 

Decreased Efficiency

It’s understandable that with normal wear and tear, a decrease in efficiency is expected. It’s when you notice a drastic difference, especially in your utility bills, that greater attention should be given. 

Why Upgrading Your HVAC System Makes Sense in NY & NJ

Yes, installing a new HVAC system can be expensive. However, the benefits can’t be ignored.

To start, you may be able to utilize one of two IRA programs to lower the financial impact of installing a new system. Programs to look into— the Energy Efficient Home Improvement Tax Credit, and the High-Efficiency Electric Home Rebate Program. It’s also safe to assume that the newer the system, the smarter it is. For example, newer models often come with built-in humidity sensors as well as the ability to program different temperatures in different parts of the home. Improved efficiency in turn leads to lower utility bills, and oftentimes better air quality. Plus, a new HVAC system often boosts the value of your home, so if you’re looking to sell, an energy-efficient HVAC is definitely something to think about. 

Newer systems are also said to have longer lifespans, and can last up to 20 years, granted this figure depends on numerous factors (like brand, quality of installation, system settings, among others), but there are a few things you can do to increase the lifespan:

  • Upgrade to a smart thermostat for energy efficient heating and cooling. 
  • Keep up with regular maintenance. We advise you to clean your air ducts every 2-4 years.
  • Take care of your outdoor unit. Remove debris like fallen twigs, or grass after mowing. Ideally, install the unit in a shaded area to prevent excess wear. And just like with vents, don’t forget about regular professional cleaning.
