Yes to most major brands, whoever installed them.
CityLine Air Conditioning services Amana, Daikin, Goodman, Lennox, Trane, American Standard, Carrier, Bryant and Comfortmaker air conditioners, furnaces and other residential HVAC equipment across Dallas-Fort Worth. We have supplier accounts for the brands we support, although parts availability depends on the model and age of the system.
Repair brands and installation brands are not the same. We install Amana equipment and repair several brands we do not sell new, including Lennox. We do not currently service York, Ruud, Coleman, Bosch or Fujitsu, because we cannot reliably source their replacement parts through our suppliers. CityLine Air Conditioning is independently owned, not part of a franchise.
Here are six of the brands we work on. We service all six, and Amana is the one we're a dealer for and install most. Not sure which you own? The next section shows where to look.
Amana is a Daikin brand, built at Daikin's campus in Waller, Texas, near Houston. CityLine Air Conditioning supplies and installs Amana air conditioning and heating systems across Dallas-Fort Worth as an Amana dealer. We service existing Amana equipment too.
Amana repair and installation »
We diagnose, repair and maintain Daikin-branded residential HVAC equipment. Daikin is also the parent company of Amana and Goodman, but that does not mean every part is interchangeable. We'll check your exact model before recommending repairs or ordering components.

Carrier and Bryant are sister brands under the same parent company, Carrier Global. We repair and service both, from air conditioners and heat pumps to furnaces. We'll check which repair parts are available for your model.

Trane and American Standard are both made by Trane Technologies, and we service both. Our technicians diagnose cooling, heating and airflow problems, then lay out the repair options based on your equipment's model and condition.

Lennox is headquartered in Richardson, where we're based. We repair and maintain Lennox heating and cooling systems, including equipment installed by other contractors. We do not install new Lennox systems, but we can price Amana equipment if replacement is the better option.

Goodman is part of the Daikin family, alongside Amana. We repair and maintain Goodman air conditioners, furnaces and heat pumps throughout DFW. Before recommending a fix, we use your model and serial numbers to check compatibility and parts.

If your brand or model is not listed, call (972) 776-4455 with the model number from your equipment label. We'll confirm coverage before you schedule a visit.
Not sure what brand or model you have? Look for the manufacturer's data plate on your outdoor AC unit or indoor furnace or air handler. A photo of its model and serial numbers helps our office identify the equipment before your appointment.
Check the exterior cabinet of the outdoor unit first. Indoor furnaces and air handlers also have equipment labels, sometimes inside an access area. Photograph only labels you can see safely. Do not remove electrical or service panels to find them.
The model number identifies the product family and configuration. Depending on the manufacturer, it can also help a technician determine cooling capacity and compatible components. In HVAC, one ton of cooling equals 12,000 British thermal units per hour, not equipment weight.
The serial number often helps identify when equipment was manufactured, but the format varies by brand. Age is useful when weighing repair against replacement, alongside condition, repair history and the availability of compatible parts.
Call (972) 776-4455 with the brand, model and serial number, or email a clear photo of the label to info@citylineairconditioning.com. We'll check available parts before making any repair promises.
Replacing an air conditioner or furnace is a major decision, regardless of brand. Before signing an installation estimate, make sure the contractor can explain system sizing, equipment compatibility and the checks performed after installation.
Ask how the contractor determined your home's heating and cooling load. A proper assessment considers more than the size of the old equipment, including insulation, windows and the home's layout. An oversized AC can cycle off too quickly and struggle with humidity control.
A central split AC relies on compatible outdoor and indoor equipment. Ask for both model numbers and, where applicable, an AHRI-rated system match. This helps you compare the tested efficiency and ensures the components are specified to work together. The AHRI certificate is the public record of that tested pair, and you can look it up in the AHRI Directory.
Ask how the installer verifies refrigerant charge, airflow and overall system operation at startup. The checks should follow the equipment manufacturer's instructions. A clear commissioning explanation tells you how the new system will be tested before the job is complete. Ask to see the readings in writing.
A good estimate should answer these questions before installation day. If a contractor can't, ask why before you sign. Explore AC installation and replacement or furnace installation and replacement to compare equipment options.
HVAC rebates depend on the current utility program, the customer's eligibility, the equipment and sometimes the installing contractor. The brand alone does not determine whether an air conditioner, heat pump or furnace qualifies. Check current requirements before choosing a new system.
Oncor's Take A Load Off, Texas program supports eligible energy-efficiency projects through participating service providers. Available measures, approval and funding can change. We take part in Oncor's efficiency work, which requires before-and-after photos of each project, so ask us whether your installation qualifies.
Based on: Oncor's current program rules and the system's efficiency rating
If your home receives natural gas from Atmos Energy, its Mid-Tex appliance rebate program offers rebates on qualifying high-efficiency furnaces. Eligibility depends on the equipment, installation date and application requirements, and payment depends on available funds. Annual fuel utilization efficiency (AFUE) expresses how efficiently a furnace converts fuel into heat.
Based on: Atmos Energy Mid-Tex terms, July 2026 to June 2027 program year
The federal tax credit for HVAC upgrades ended for systems installed after 2025, and Texas's planned home energy rebates haven't opened yet. Programs checked October 2026.
Manufacturer promotions and utility incentives follow different rules. A manufacturer offer may be restricted to participating dealers and models, while a utility program may require specific efficiency ratings, installation practices and approved service providers. We'll review any documented incentive with your replacement options, but qualification and payment are determined by the program.
Yes. Carrier, Trane and their sister brands, Bryant and American Standard, are all ones we repair and maintain across DFW, including systems other contractors installed.
No. We service Lennox equipment, but new Lennox systems are sold through Lennox's own dealers, and we're not one. We can price an Amana replacement instead.
The manufacturer's warranty stays with your equipment and its registration. Our repair work is covered by our 365-day money-back guarantee, once we've had a chance to make it right.
No. You can switch brands, but the new outdoor and indoor equipment must be compatible, rated together and sized for your home.
It depends on your house rather than on us: its heating and cooling needs, the ductwork and your budget. We install Amana systems and price the packages that fit.
Office hours 8 AM to 6 PM, with phones answered around the clock.
