Repair or Replace? Expert Advice on Making the Right Decision for Your HVAC Unit

By Aztil – December 4, 2024

Air conditioners last between 10 and 20 years depending on the model, maintenance, and climate. Some have long lifespans while others fail early. While there is no exact date, the time to replace your AC is based on when it needs repairs, and how serious those repairs become. Deciding whether to repair or replace your HVAC is crucial for your home’s comfort, budget, and energy efficiency. Consider new regulations like the AIM Act 2025. If you want to save time and money while ensuring reliable heating and cooling, we can help you determine the best course based on several important factors.

1. Age of the Unit

Most AC units have a lifespan of 10-20 years, with an average reliable performance of 15 years. If your AC is over 10 years old, consider a replacement rather than repairs. An AC unit loses efficiency as it ages, leading to higher energy bills and more frequent repairs. Eventually, it will be more cost-effective to replace instead of continuing repairs.

The AIM Act 2025

The AIM Act will phase out older eco-harmful refrigerants that pose global warming risks. Older ACs may become more costly if they use banned refrigerants like R-401A. If your old AC has a refrigerant leak, it may be a good time to upgrade.

2. Cost of Repairs vs. Replacement

The 50% rule states that if a repair costs 50% or more of the cost of a new appliance, then replacement is the wise choice. You will get better performance from a new unit, so the other half of the price will pay itself back quickly compared to the lost expense of repairing a unit that will continue to fail and need more costly repairs in the future.

With the AIM Act, you can also be certain that HVAC replacements in 2024 will all be manufactured with eco-friendly refrigerants. An upgrade will be good for the environment, more efficient, and cheaper for many years.

3. Energy Efficiency and Your Utility Bills

How energy-efficient is your old HVAC unit? HVACs have to use more electricity for heating and cooling as the years go by. A steady increase in your seasonal power bills can mean your HVAC will cost more than you realize. Repairing an older unit may come with that half-hidden higher cost of continued operation.

Upgrading to a more efficient new HVAC comes with advanced technology, a higher SEER (Seasonal Energy Efficiency Ratio) rating, and lower power bills. With the AIM Act, newer systems also use low-GWP refrigerants, making them eco-friendlier and more efficient, leading to lower utility bills.

4. Frequency of Breakdowns

Constant repairs are a sign that your AC will continue to fall. If repairs are more than once a year, it’s probably time to schedule your HVAC replacement. The AIM Act phase-down also means it will become more costly to service older units with phased-out refrigerants.

5. Indoor Comfort and Air Quality

An older HVAC may struggle to keep up with your home’s air needs. If you notice hot and cold spots, the blower fan or motor fails to push enough air evenly through the house. If you notice poor air quality, it could mean a failure of filtration or humidity control.

A newer system that meets the AIM Act standards provides advanced efficiency and environmental controls. You can ensure perfect air balance and reduce pollutants and allergens in your home.

6. Environmental Impact and AIM Act Compliance

The AIM Act 2025 ensures that new HVAC units are more eco-friendly than older models by phasing out high-GWP refrigerants. New systems will reduce your carbon footprint with eco-friendly refrigerants and more efficient electricity use.

7. Current Rebates and Incentives

If now is the right time to replace your HVAC, several great savings opportunities are available. Many utility companies offer rebates, discounts, and other incentives for purchasing a new high-efficiency AIM Act-compliant system. You can use these savings to reduce the upfront costs of your energy-saving upgrade. This is a chance to reduce installation costs and start saving immediately with lower seasonal power bills.

Making the Best Choice for Your Home

Should you repair your HVAC or plan to replace it? Consider your system’s age, repair frequency, seasonal power bills, and your current home comfort. If now is the right time to replace, take advantage of the savings and quality upgrades inspired by the AIM Act 2025, which drives eco-friendly and energy-efficient changes in the HVAC industry.

Alvin Hagans

Excellent job by Niko

Timothy Shay

Rafael was great. He explained what he was doing throughout his repair

David Wind

Our air conditioner broke down. We called Atzil and they sent Antonio Moreno over within an hour. He assessed the problem to be a burned out motor and ordered the new one. It was still under warranty. He said it would be in within two days and installed so hopefully that’ll be so and
I will update this when that happens

Sandra Sheptin

Dana was excellent!!! Highly recommend him to everyone!

Cari Adamonis

The AC maintenance service was excellent. Niko Garza was professional, helpful, kind, and was instrumental in arranging for the next Senior Technician to solve the AC problem that I am having. That service will be sometime today. He also recommended the dryer vent cleaning and the in-line AC cleaning, of which I scheduled for Monday and paid today. My husband has been very ill for the past 4 years and in the hospital right now. Aztil has arranged the services, after Niko explained the situation, so that they will be completed before he comes home because a patient on oxygen and a feeding tube cannot be without power to the whole house, even a short shut down would endanger him. Thank you Niko!

Technician Rick Cochran did an excellent job replacing the AC breaker and ensuring that everything was in correct working condition. I really appreciated his kindness and professional demeanor. Thank you Rick!

Today Technician Alex Molina completed the services (dryer lint trap cleaning and inline air handler cleaning). Once again, I was fortunate to have a professional, gracious, and thoughtful person come to my house to perform the services. Thank you so much Alex!

Lisa Leonard - Reese

If I could leave ten stars I would! Went under an annual contract two years ago and have had just about every service since. Every technician has been great but Ricardo is the absolute best. He and his team were professional and easy to talk to and I learned about the inner workings of the system so I can have a better idea of how to maintain optimum performance. Cleaning the ducts is often a huge mess and I didn’t find a single bit of debris even in the most awkward places. There are few businesses you can just trust and this is one of them.

I’m updating this to say I am still under contract with them and technicians Rafael and Adrian went above and beyond working on a broken motor and cleaning the blower which took hours. Rafael is extremely knowledgeable and patient as he explained several different options available to deal with a 30 year+ dirty duct system. In the end we are going with a duct cleaning plus aero seal which is about half the cost of a full duct replacement. In find them trust worthy.

Response from the owner:We are overjoyed to hear that our service has exceeded your expectations and you would have given us ten stars if possible. Being on an annual contract for the past two years, you have availed a majority of our services and we are pleased to know that every technician has been great but Ricardo stands out as the best. He and his team were professional and easy to communicate with and you were able to learn more about your system and how to maintain it. We are especially pleased to hear that you were impressed with the thoroughness of the cleaning of the ducts, with no debris found even in hard-to-reach areas. We are honored that you consider us as a business you can trust, and we will continue to work hard to earn that trust and provide exceptional service to all of our customers.

Kenneth Ciani

Mark O*Connel responded to service my AC unit. He was friendly. Explained what he was going to do. Completed all tasks and gave me some good advice to keep my unit running correctly. Very satisfied with service.

Response from the owner:Hi Kenneth, thank you for your kind words! We're so glad to hear that Marco did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.

Sheryl Cholish

The technician was wonderful! Curtious, professional and made me feel very comfortable. He explained everything so that I understood it. HIghly recommend this company.

Response from the owner:Hi Sheryl, thank you for your kind words! We're so glad to hear that Aztil did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.

Julie Pollitz

Jordan and Adrian came to clean my a/c ducts and seal my HVAC system. They could not have been nicer, more professional, knowledgeable or polite. They were unbelievably helpful and took the time to explain things so I understood what was going on. I highly recommend Aztil and would request Jordan and Adrian for any future work.

Response from the owner:Hi Julie, thank you for your kind words! We're so glad to hear that Paul did an excellent job and that you were pleased with the outcome. Thank you for being a valued customer.

Yvette Savage

This company is excellent. Always there to help you with your air conditioning and heating needs. Lorenzo was the technician very efficient timely and did a great job. Thank you Aztil
