“When we started the business in 1978 the foundation of the company was built on the primary objectives of providing quality service and installations at a fair price. We receive specialized training and continue our technical education throughout our careers, allowing us to offer better products, better knowledge, and better service! I want our customers to be comfortable in their homes and comfortable doing business with us. Come home to comfort with Hauser Heating & Air Conditioning.” Sincerely, Roy Hauser Company Founder

"Hauser inspected an upscale furnace we bought from them. They said nothing was wrong ? including a fan one of their competitors said was going out. 2 weeks later when we first used the furnace, Hauser had to replace the fan. They said they could not predict a fan going out! Apparently their competitors can. We were a few days past our warranty, but Hauser agreed to replace under warranty (parts, not installation). They charged $1,792 for a 20 - 30 min installation, an effective labor rate of $3,600/hr. Numerous calls were ignore except business person explained that this is not an hourly rate, just the price they charge for this installation. This is greedy and unethical. They use linguistic obfuscation, calling it an ?installation fee? ? independent of an hourly rate. It is immoral: a grifter?s flim-flam shell game. An annual labor rate of $7.5 M is not reasonable by anyone?s standards. "

Heating and Air Conditioning questions, answered by experts

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

Yes, high-efficiency models reduce environmental impact with lower energy use.

When a compressor gets overheated in central air systems or heat pumps, it can still cool your home for a while until it eventually gives out. If the compressor is chronically overheated and no one addresses the root cause, it will create an incredibly expensive problem when your entire HVAC system breaks down and stops working altogether.

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.
