When your heating or air conditioning system stops working, deciding whether to repair or replace it can be stressful, especially if it breaks down during a heat wave or very cold weather. This guide answers common repair vs. replace questions and provides information to help you make a decision.
When deciding whether to repair or replace your system, consider:- Warranty and system age
- If your unit is under warranty, you should repair it, as a portion of the cost may be covered.
- If your warranty has expired, and your system is near the end of its lifespan, replacement may be the best choice. Before making a decision, be sure to consider the type and cost of the repair.
- Type and cost of repair
- Minor fix: If the repair is simple and inexpensive, fixing the system will get you up and running. However, remember that older systems often have more issues over time. Ask your HVAC technician about the condition of your current unit.
- Major fix: If the repair is significant and expensive, replacement is a better choice. A new unit offers longer-term benefits and includes a new warranty.
- Warning signs If you see these signs of an aging system, replacement is recommended:
- Several HVAC system repairs needed in the same year.
- A change in your home comfort, like uneven temperatures or decreased airflow.
- Unexpected increases in your energy bill.
- Future plans The length of time you plan to stay in your current home may also impact your decision.
- If you plan to move soon, repair is a better choice because you likely won’t benefit from the long-term savings a costly new unit can provide.
- If you plan to stay in your home for at least five more years, replacement is recommended.
A qualified HVAC professional can determine what caused your system to break down and recommend a range of options to fix it. Understanding the benefits and trade-offs of each choice will help you feel more confident in the decision you make.
How do I get an estimate?
The first step in getting your system up and running again is to schedule a service call with a local heating, ventilation, and air conditioning (HVAC) company. Learn how to find a trusted HVAC professional.
When making your appointment, the company will ask:
- What kind of problem are you having?
- What type of system do you have?
- Where is the unit located on your property?
This information helps the technician bring the right tools to quickly find the problem. Once they determine what the problem is, they’ll give you a few options for fixing it and a cost estimate for each.
How much does an HVAC repair cost?
The cost depends on what parts are needed and how long it takes to make the repair.
Why does the warrany matter?
If your system is under warranty, you should repair it because the cost of parts may be covered. Warranty terms vary, so be sure to check the details of your warranty and its expiration date. Many HVAC companies will help you with warranty questions.
If you have an older system that’s out of warranty—meaning you pay the full cost of any repair—and it needs a major fix, you should replace it instead of repairing it. The money you spend can go toward a new unit that makes your home more comfortable, saves energy, and gives you additional features.
How long do HVAC units last?
How long an HVAC unit lasts depends on several things, including its type, how you use it, where it’s located, and how often you maintain it.
Needing a repair isn’t unusual. All HVAC parts do wear out eventually from use. However, frequent repairs may mean there is a bigger issue or that your unit is nearing the end of its service life.
Here are some estimates for common equipment lifespans, according to the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), a resource for HVAC professionals.
Why does the age of my system matter?
As heating and air conditioning units get older, they may start to have problems. Common signs that a unit is nearing the end of its life include:
- Frequent breakdowns.
- Unexpected increases in energy bills.
- Uneven temperatures throughout your home.
- Odd smells or noises.
- Excessive humidity.
All of these can make your home less comfortable, increase expenses, and lead to more frequent HVAC system repairs.
Also, older systems are more expensive to maintain over time because it’s harder or impossible to get parts as newer HVAC technologies become available.
What are the benefits of a new system?
Newer heating and cooling systems offer many cost-saving, comfort, and environmental benefits:
- Energy efficiency: New systems run more efficiently, which helps to reduce energy use and lower energy bills.
- Better indoor air quality: New systems include enhanced features that help improve indoor air quality.
- More features: New systems offer more capabilities, including fine-tuning features and smart controls.
- Reduced environmental impact: Newer air conditioners and heat pumps use more cost-efficient and less-toxic refrigerants that are safer and more eco friendly.
When you decide to replace your heating or air conditioning unit, your HVAC contractor will help you choose the right-size unit with the features you want. They’ll also go over warranties and money-saving and payment options, including rebates, tax credits, and financing.
