Where can I get parts for my Carrier equipment?

We are your best resource for identifying and supplying the correct, current parts for your system, as well as pricing and availability.

Why can't I find the correct size furnace filter at my local home improvement store?

The filter shipped with your air conditioning unit is made from higher-quality materials than those of the disposable filters found in retail stores. For that reason, replacement Carrier filters can only be purchased through a Carrier dealer. However, keep in mind that Carrier filters are reusable, and can be washed by hand in cold water.

I need help troubleshooting a problem with my equipment.

We are glad to help you. Our trained an certified technicians can troubleshoot your problem and provide solutions and options. if it turns out that your air conditioning equipment cannot be repaired to your satisfaction, and you choose to buy a new Carrier system, we will give you 10% off parts and labor for the new Carrier equipment.

Where can I find literature about my system, such as owners manuals, installation guides and product specifications? We are your source for installation and product specifications.

Which equipment will best fit my home?

There are many factors that affect the sizing and specifications of your system, including square footage, insulation, window surface and configuration, geographic location of your home, duct sizing and arrangement, and many others. We can perform an in-home load analysis to determine which equipment combinations will perfectly suit your home and your family's needs.

What does my Carrier warranty cover?

Under the standard factory warranty, Carrier covers parts that fail during the warranty period due to defect in the part. The warranty does not cover labor. A warranty certificate was included with your homeowner information packet, and is specific to the model numbers, serial numbers and installation dates of your products. If you cannot find your warranty certificate, we can provide your with the information.

How does the Carrier 100% Satisfaction Guarantee work?

It's pretty simple. If within one year of the original installation, you are not satisfied with your new Carrier unit installed by Dallas Plumbing Company, we will first determine if there is a problem with the unit and adjust or repair it at no charge. If after that, you are still not satisfied, at your request, we will remove the Carrier system and either refund your original purchase price or replace it with a different Carrier system. It is your choice. If we replace it with a different Carrier system of greater value, you will only be required to pay for any additional cost of the new equipment. The same satisfaction guarantee will apply to any new Carrier equipment we install.

What is my repair warranty?

Repairs for air conditioning, heating and plumbing are warranteed for 30 days, including parts provided by Dallas Plumbing Company and labor. Labor is not included for repair of parts or materials provided by others. For example, we will warranty workmanship for our work on any make or model. That means, if there is any problem with our work, we will fix it at no charge to you. However, if we properly install a part provided by you, and the part proves to be defective, we will replace the part, but you will be charged for the labor and materials. Please give our trained staff a call if you have any questions about our warranties.

How much will a new system cost?

Your system cost will depend on a variety of factors, including the size of the structure, windows and insulation, ceiling height, location access and comfort preferences. We can give you a firm quotation on a system that will meet your needs affordably and efficiently.

Why is the SEER rating on the Energy Guide different than what my dealer quoted?

Each split system cooling unit has a nominal SEER rating. This rating can be increased with the upgrade of the indoor unit. The SEER rating of a system is derived based on the combination of equipment installed in the home. The outdoor equipment (heat pump or air conditioner), as well as the indoor equipment (evaporator coil and furnace, or air handler), play a vital role in the rating. Please call us for the information.

How can I talk to a factory engineer regarding a problem I am having with my Carrier equipment? Simply contact us as your engineering and technical resource.

What is the life expectancy of my unit?

Our products are among the longest lasting heating and cooling products available. For your specific equipment, there are many variables that affect life expectancy, and of course, the regularity of routine maintenance. We can take a look at your system and suggest a remaining lifespan.

I am an Architect and need application/specification information so that I can specify your HVAC products... where do I obtain this information?

We can provide you with the specifications, and can also set you up to access the information yourself. If you are seeking specifications on older equipment, so as to specify something similar, it will be helpful if you have the model and serial number available.
