Should I Repair or Replace My HVAC System?

November 8, 2022

Does My AC System Need To Be Replaced or Can It Be Fixed?

When contemplating whether to repair or replace your HVAC system, there are a few factors to consider. Although repair may seem like the cheaper fix, it isn’t always the best option for your home. There are pros and cons to both repair and replacement, and we hope to help make your decision easier with these things to evaluate!


Depending on your situation, repairing your AC system can be the best solution. Typically, repair is the cheaper option when compared to replacement. Who doesn’t love to save money? One thing to understand in your decision to repair or replace is if repair is actually cheaper in the long run. Will this repair be a temporary fix? Does your system have frequent breakdowns? Your heating and cooling unit is much like your car. When your car breaks down, you take it to the body shop and have it fixed. If the car repair is unfixable or costly, buying a new car is a possible solution.


Unfortunately, even heating and cooling units have an expiration date. Replacing your HVAC system is an investment, but it does have benefits. If you are in the market to replace, your current system is likely causing you stress from breakdowns. Replacing as a whole can give homeowners peace of mind knowing they have a reliable unit in the summer and winter months. New HVAC units have higher efficiency which increases your overall comfort.

Things to Consider

We encourage you to consider these factors when deciding to repair or replace your HVAC system.

The Age of Your Unit.

HVAC systems typically last 10-15 years with proper maintenance. The chance of breakdowns and frequent repairs increase after your unit hits the 10 year mark. Considering this, if your unit is 10 years or older it is likely to continue needing repairs until it eventually gives out. Frequent repairs and technician calls can be expensive, which makes replacement a good option.

The Cost of the Repair.

Many HVAC technicians use the “$5,000 rule.” This rule of thumb multiplies the age of the unit by the repair cost, and if the total exceeds $5,000 it may be best to replace the unit. If the repair is inexpensive and your technician recommends this as the best option, repair could be your best choice.

The Efficiency of Your Unit.

Ask your Glenmont Air Conditioning & Heating technician to evaluate your unit’s Seasonal Energy Efficiency Ration (SEER) rating. The higher the SEER rating, the more efficient your unit is. This rating can help determine your possible savings by replacing your unit.

How Long Will You Live in Your House?

Evaluate how long you plan on living in your home before buying a new unit. If you plan on living there for many years to come, replacement could be beneficial. If you are selling your home, a new HVAC unit can increase your resale value and many buyers ask for replacement.

The Cost of Your Energy Bills.

Older units may be the cause of high utility bills due the amount of energy they use. New units are more energy efficient, which can reduce your monthly energy bill.
