Hamstra Value:

What makes us different? All the HVAC companies in town can sell you units and ductwork and they can all install them, but it is the service they provide you that makes all the difference.

Below is a list of what makes us different from the competition. It is because of these value added services that we have never once advertised in 23 years of being in business. We have grown into one of the largest HVAC companies in Southern Arizona simply by word of mouth. How many other HVAC companies out there can say that?

• The highest quality HVAC products in the industry - We do not attempt to cut cost or cut corners by selling customers inferior products. All the materials we use to complete HVAC installs are top shelf products that have been chosen for their quality. We primarily sell and install Trane/American Standard and Lennox air conditioning equipment. Both these brands are consistently rated as the most reliable and highest performing in the industry by consumer reports.
• Superior Engineering - Our customers receive the best performing, quietest, and most reliable HVAC systems on the market. This is due to our superior knowledge of the engineering and duct design process. We guarantee that our HVAC systems will produce an indoor temperature of 75 degrees when it is 105 degrees outside. This is a claim that most other HVAC companies cannot make and is a standard that most would not even attempt.
• Our customers come first - A lot of other companies claim they have great customer service, but we actually live up to this claim. If you are not satisfied with our products or services, we will do everything in our power to make it right. In the "Guarantees" section of this website you can view all of our satisfaction guarantees. Find another company that has the confidence in itself to make you these same promises.
• Professionalism - We deliver on our promises and fulfill all of our commitments. Hamstra owners and managers are constantly receiving positive feedback from builders about the company's professionalism. Also, we execute a preparation and quality inspection process for each and every job that is unmatched by competitors. Our installation coordinators work hand in hand with builders and customers to make sure the job is done right and that all of the customers needs are met.
