Constellation’s AC Protection Bundle is one of the few electricity plans in Texas that combines an electricity rate with home protection coverage. The plan includes AC protection for 2 units, HVAC monitoring, heating system coverage, and water heater coverage, according to the Electricity Facts Label. It is also a 12-month rate electricity plan with usage bill credits.
At first, this may sound attractive, especially if you own a home and are worried about expensive AC repairs. But before looking at the protection bundle, we need to start with the biggest problem:
At first, this may sound attractive, especially if you own a home and are worried about expensive AC repairs. But before looking at the protection bundle, we need to start with the biggest problem:
This is a bill-credit plan. And for many customers, that alone is enough reason to avoid it.
When You Should Not Use This Plan
- If you live in an apartment or a small house, this plan is probably not for you. The reason is simple: this plan depends heavily on usage credits. If you do not reach the required usage levels, you leave money on the table. The EFL shows a $35 residential usage credit when usage is at least 1,000 kWh, plus an additional $15 credit when usage is at least 2,000 kWh. That means the plan looks much better at 1,000 kWh and 2,000 kWh than it may look at lower usage levels.
- For apartments, townhomes, and smaller homes under roughly 1,500 square feet, it is very possible to stay below 1,000 kWh for several months of the year. If that happens, you miss the credit and your effective rate becomes much higher.
- So before even analyzing the AC protection bundle, the first warning is clear: If you cannot consistently reach 1,000 kWh, stay away from this plan.
What if you have a 2,000+ sq. ft. house?
To properly analyze this plan, we compare it against competitive True Fixed plans in the market. The goal is not only to see which plan has the lower advertised rate. The real question is:
How much extra are you paying for the AC protection bundle?
Once we estimate that difference, we can decide whether the added AC and home protection coverage is worth the higher electricity cost.
The data for this Constellation plan is collected directly from the offer shown on Constellation’s website and the Electricity Facts Label. This data is usually reviewed at least once per month. The True Fixed plans used for comparison are usually checked every 48 hours. Their pricing is collected either from Power to Choose or directly from the electricity provider’s website.
This comparison is based on the Oncor service area. However, the cost difference between this type of bundled plan and competitive True Fixed plans is usually similar across other TDUs.

AC Protect vs Competitive True Fixed Plan (Oncor)
As you can see from the curve above, there is a significant difference between the two plans. The AC Protect plan is more expensive than a competitive True Fixed plan across many usage levels.
The table below shows the estimated monthly bill based on different usage levels. The green value in each column represents the cheaper option at that usage level. Both plans are shown together so you can clearly see the difference.

Is the AC Protection Worth the Extra Cost?
This is the key question. Based on the current Oncor comparison shown above, the AC Protect plan is generally more expensive than a competitive True Fixed plan, although the difference varies by usage level. At around 1,000 kWh, the two plans cost approximately the same. However, at 1,500 kWh, AC Protect costs roughly $15–$20 more per month, or close to $200 more over the 11-month term if usage remains at that level.
For larger homes, the difference increases. At 2,000 kWh, AC Protect costs around $20 more per month. At 2,500 kWh, the difference increases to approximately $35–$40 per month, while at 3,000 kWh, it exceeds $50 per month. The protection bundle may provide some value, but the additional electricity cost can add up quickly, especially for higher-usage homes.
So the real question is not whether AC protection has value. The question is:
Is this protection worth paying hundreds of dollars more per year through your electricity plan?
AC Protect Pros
The AC protection bundle may have some benefits, especially for homeowners who want extra peace of mind.
Possible advantages include:
- Service protection for AC systems
- Coverage tied directly to a reputable electricity provider
- Potentially easier customer service than some traditional home warranty companies
- Annual efficiency tune-up
- Protection for expensive AC-related repairs, subject to the plan limits and exclusions
Constellation also has a stronger brand reputation than many home warranty companies. That matters because one of the biggest complaints with home warranty providers is claim delays, denied claims, and poor service experience. If you already know you want some type of AC protection, getting it through Constellation may feel more reliable than buying it from a lower-rated warranty company. But that does not automatically mean the plan is a good deal.
AC Protect Cons
The biggest problem is that the protection is not free. You are paying for it through a more expensive electricity plan.
Other concerns include:
- The electricity plan is still a bill-credit plan
- You may miss the 1,000 kWh or 2,000 kWh credits in some months
- The repair coverage may be capped
- Some parts or services may not be included
- You may need to use Constellation’s service process instead of choosing your own contractor
- If the AC system has a major failure, the coverage may not be enough to cover the full replacement cost
This is important because many common AC repairs are not extremely expensive. For example, some homeowners may be able to handle smaller issues directly with a local HVAC technician. But if the system has a major failure, the coverage cap and exclusions become very important.
Who Might Consider This Plan?
This plan may make sense for a very specific type of customer:
You own a medium or large home, your usage is usually above 1,000 kWh, and you want some AC protection from a well-known company.
It may be more attractive if:
- Your home is around 2,000–2,500 square feet or larger
- You consistently use more than 1,000 kWh
- You are worried about AC repair costs
- You do not want to shop separately for a home warranty
- You prefer dealing with Constellation instead of a traditional warranty company
Even then, you should compare the extra electricity cost against the cost of buying separate AC or home warranty protection.
Who Should Avoid This Plan?
You should probably avoid this plan if:
- You live in an apartment
- You live in a small home
- Your usage often falls below 1,000 kWh
- You dislike bill-credit plans
- You would rather save the monthly difference yourself for future repairs
If you are a do-it-yourself homeowner or you already have a reliable HVAC technician, this plan becomes harder to justify.
Final Recommendation
We do not recommend Constellation’s AC Protection Bundle for most customers.
The main reason is that it is still a bill-credit electricity plan. At Clear Energy Facts, we are strongly against bill-credit plans because they can make the advertised rate look better than the real cost many customers actually pay. This plan includes a $35 usage credit at 1,000 kWh and an additional $15 credit at 2,000 kWh, so missing those usage levels can make the plan more expensive.
The AC protection bundle does add some value, but the Oncor comparison shows the AC Protect plan usually has a higher estimated bill than the competitive True Fixed plan in the supplied usage table, with only a very small advantage at 1,000 kWh. For many customers, it may be better to choose a competitive True Fixed plan and compare separate AC or home protection options if they still want that coverage.
