These figures come from price lists published by air conditioning companies working Mesquite and the east side of Dallas County, alongside the flat mechanical permit the city charges, the utility incentive that offsets a replacement, and the coverage the state requires of the contractor.

The 2025 Home Energy Efficiency program manual caps the contractor incentive by tonnage: $2,000 at two tons, $2,600 at three, $3,400 at five.
Texas requires a Class A air conditioning and refrigeration contractor to carry $300,000 per occurrence and $600,000 aggregate. Class B minimums are a third of that.

Every range below is what companies working in Mesquite publish for that job, gathered from the numbered price pages under the table. It spans what several of them show, so the figures move with the specifics of the property and with who does the work. Nothing here is a quote, and no business has set a price on this page. A real number comes from whoever looks at the job.
| The job | Range seen | Billed as | What moves it |
|---|---|---|---|
| Service call and diagnosis on a system that quit cooling | $75–$1501234 | per visit | East side shops post this as a flat fee. Whether it is credited toward the repair varies, and it is worth asking before the truck rolls. |
| Same day call answered after hours or overnight | $150–$25023 | surcharge on top of the repair | This is the premium alone, added to whatever the repair costs. One Mesquite page posts it as a flat after hours charge. |
| Run capacitor replaced, diagnosis included | $150–$8501345 | parts and labor | The spread on one part is real. Two east county lists put a complete capacitor service in the hundreds, not the tens. |
| Condenser fan motor replaced | $400–$2,80046 | parts and labor | A universal replacement motor sits at the bottom. A factory variable speed motor on a newer condenser is the top figure. |
| Blower motor replaced in the indoor unit | $450–$4,200146 | parts and labor | An older direct drive blower is the low figure. A variable speed motor with its own control module reaches the high one. |
| Leak found and refrigerant replaced on an older R-22 system | $350–$1,500234 | leak search plus refrigerant | Phased out refrigerant is the reason. One local page posts R-22 at double the per pound figure it charges for R-410A. |
| Whole system replaced with the city permit pulled | $5,200–$20,00027 | installed | One Rowlett page states the city permit and inspection sit inside its figure. Duct and electrical work is what pushes past ten thousand. |

Mesquite is not a new suburb. Much of it was built out through the 1960s and 1970s. That history explains most of the spread in the table above: original duct systems, a furnace and coil crammed into a hall closet or a low attic, undersized returns, and a shrinking number of systems designed for R-22 refrigerant.
R-22 is the expensive part. It has been phased out of production and the price of what remains reflects that. One east side price list puts R-22 at roughly double the per pound figure it charges for R-410A, so an identical leak repair on a twenty year old system is not comparable to one on a ten year old system.
East Dallas County shops tend to price service calls as a flat diagnostic rather than an open hourly rate, which helps a homeowner compare quotes. Watch two things anyway. First, whether that fee is credited toward the repair. Second, the after hours premium, which several local pages publish as a standalone figure added on top of the repair. That is why the table lists the premium separately: a midnight visit for a failed capacitor is the daytime capacitor price plus the surcharge. If the house is holding a survivable temperature and nobody in it is medically vulnerable, waiting until business hours is usually cheaper.
Mesquite prices a residential mechanical permit, condenser and furnace replacement included, at a flat $65, and a residential plumbing permit at the same $65, under the City of Mesquite code of ordinances, permit fee sections 12-102 and 12-104. Against a five figure replacement that is a rounding error, but it is a test: a contractor unwilling to pull a $65 permit is telling you the work may go uninspected.
The number that actually moves a replacement decision is the utility incentive. Oncor's 2025 residential efficiency program pays an incentive capped by system size, from $2,000 at two tons up to $3,400 at five, on qualifying high efficiency equipment installed by an enrolled contractor. It only reaches the homeowner if the company doing the work participates, so ask whether it does and whether the incentive is already inside the quoted price.
There is a state floor underneath all of this. Texas requires a Class A air conditioning and refrigeration contractor to carry $300,000 per occurrence in property damage and bodily injury coverage, with a $600,000 aggregate, and Class B minimums at a third of those amounts. That coverage is part of why a properly registered company cannot match a truck and a phone number on price.
An estimate should separate the service call fee, state whether it is credited, and put the after hours premium on its own line if one applies. Refrigerant should be quoted per pound with the type named, because R-22 versus R-410A is the difference between a reasonable repair and a bad investment. A leak search is its own line, separate from the repair, and a repair claim should be backed by where the leak was found.
On a replacement, the estimate names both pieces of equipment by model number, the tonnage, the efficiency rating, the fate of the existing duct system, whether the coil and lineset are new, the thermostat, the city permit, and the Oncor incentive if one applies.
The pattern here is the aging system used as leverage on a small repair. A twenty year old unit in Mesquite genuinely is near the end of its service life. That does not make a $500 repair the wrong choice, and it does not justify skipping the diagnosis. Weigh the repair cost against the years the equipment can plausibly still run and against the incentive available on a replacement, and ask for the failed part and the reading that condemned it.
The second pattern is a full duct replacement bundled into every changeout by default. Some houses in this city need it. Plenty need two hours of sealing and one new return, and a static pressure reading tells the difference.
Cost pages built on national data do not know about a 1970s hall closet that will not take a modern furnace cabinet, or a panel with no room for a larger circuit. Left out too: recovery of phased out refrigerant, the city permit, the incentive paperwork an enrolled contractor files.
Get a technician to the equipment, measurements behind the diagnosis, and the repair amount before work begins. If a breaker will not stay on, anything smells hot, or water is near electrical equipment, shut the cooling system down and request urgent help.
