Owner Randy came to assess condition of the unit and determine unit was in need of replacement. This unit was 27 years old. Explained the changes in the coolant currently used and provided 2 different manufacturers and prices. On day of repair, the crew came and were friendly, informative and diligent. Unit and all associated work which included tubing, insulation and wiring and clean up were all completed by 3PM. I Highly recommend Rand-Aire

Randy Miller and his crew do an exceptional job. He is very professional, efficient, friendly and always answers his phone or gets back to you quickly. Can't recommend Randy Miller's RandAire Mechanical Contractors enough. They installed and maintained our 15-16 HVAC systems at our industrial building for 40 years.
Frequently Asked Questions About Rand Aire Mechanical Contractors Inc
Where can I get parts for my Bryant equipment?
Your experienced Bryant dealer is the 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 Bryant unit is made from higher-quality materials than those of the disposable filters found in retail stores. For that reason, replacement Bryant filters can only be purchased through a Bryant dealer. However, keep in mind that Bryant filters are reusable, and can be washed by hand in cold water.
I need help troubleshooting a problem with my equipment.
Your Bryant dealer is excellent at troubleshooting, and is glad to help you. In addition, Bryant also provides a network of troubleshooting technicians at Bryant Distribution centers across the country. Should your dealer encounter a situation that requires additional factory help, just ask him or her to contact their Bryant Service Manager for assistance.
Where can I find literature about my Bryant products?
Our thorough Service and Support section has complete information with downloadable manuals and guides. Just use the search tool to locate the right literature for your model.
Which Bryant 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. Your Bryant dealer 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 warranty cover?
Under the standard factory warranty, Bryant covers the parts, and your installer covers the 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, your Bryant dealer will also be able to provide you with the information.
How much will a new system cost?
Please contact your local experienced Bryant dealer for pricing. Each independent experienced Bryant dealer establishes his or her own equipment and labor prices.
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. Your dealer has access to the equipment specifications and can provide you with the actual combination rating for your system.
How can I talk to a factory engineer regarding a problem I am having with my Bryant equipment?
Simply contact your local Bryant dealer, who is your experienced engineering and technical resource.
What is the life expectancy of my unit?
Dependable Bryant products are among the longest lasting heating and cooling products available. For your specific equipment, there are many variables that affect life expectancy, especially including the regularity of routine maintenance. Contact your local Bryant dealer for insight into the remaining lifespan of your system.
