Questions & Answers

Customer Questions

Is Carrier a good brand of air conditioner?

Carrier is one of the top brands on the market, offering a versatile range of air conditioners. Units offer advanced features, high efficiency and low noise levels. While their systems are more expensive than others, Carrier products are guaranteed to last.

Is Carrier worth the cost?

Carrier has some of the most expensive air conditioners, so many homeowners wonder if Carrier AC units are worth the price. Knowing why Carrier products are more expensive can help you decide if they're worth it, so here are some reasons:

Quality is the first reason. Carrier uses quality components and great designs to build lasting air conditioners that don’t typically require a lot of repairs.

Name is another important factor. When you buy Carrier, part of what you're paying for is the name. It’s like the difference between buying brand name and off-brand shoes: they might be made in the same factory, so what you're really paying for is the reputation and prestige.

One final thing to keep in mind is that no matter what air conditioner brand and model you buy, something that can be just as important is the contractor you buy it from and hire to install and maintain it.

How long will my Carrier A/C last?

Carrier says their air conditioners are designed to last between 10 and 15 years, and the 10-year warranty backs up this assertion. However, it is possible to get more than 15 years from a Carrier air conditioner, especially if you have a higher-end Infinity model that’s sized properly for your house, installed professionally, maintained annually, repaired when needed, and run at optimal temperatures.

What is the average life of a Carrier air conditioner?

Carrier air conditioner is one of the most reputable brands of AC. A Carrier air conditioner can last up to 15 to 25 years. This depends on different factors, but you can expect your carrier AC to function for at least two decades if you properly maintain it.

What company makes Carrier air conditioners?

Carrier was founded in 1915 as an independent company manufacturing and distributing heating, ventilating and air conditioning (HVAC) systems, and has since expanded to include manufacturing commercial refrigeration and foodservice equipment, and fire and security technologies. As a unit of United Technologies Corporation, Carrier today operates 67 manufacturing facilities on six continents. Over 60,000 employees in more than 170 countries research, develop and manufacture Carrier air conditioning equipment and related technology.

Gsha are the best! They are punctual precise and the best guys for our heating and ac needs. Ive used them for over 7 years and have referred them to everyone.

Noel Martinez
Rated 5 out of 5

Incredibly good service. They came to provide a quote within 24 hours, and provided several efficiency options across several OEMs. After we quoted six other companies, GSHA had the best pricing, so we went with them. They showed up the next day, demoed the old system and installed the new furnace and A/C in one day. We couldn’t be happier. The quote provided was exactly what we paid; no secret add ons. They deserve all the stars.

Scheduled on line for our yearly AC cleaning and checkup. Service Tech showed up on time. We even received a text 15 minutes prior to his arrival stating he was in route along with the tech’s name. We talked briefly, asked if we were having an problems. He then performed the the cleaning and service. Very professional. After using several other companies over the years, GSHA Services is truly the best.
