For many homeowners, the search for a reputable HVAC company can be a difficult and frustrating one, whether to install a system or to come out and do a Furnace repair on an existing one that isn't performing as it should be. While there are many businesses out there that will offer their services, finding one that will provide the best quality service for your money can be real challenge. You certainly shouldn't go for the cheapest service available, but you shouldn't have to break the bank, either. You will want to consider reputation, as well as other factors, for example you should visit online sites like in your research so you can make up your own mind based on testimonials. Here are a few more things that you should look at when searching for a reputable HVAC company:

Certified Technicians

The first thing you should look for during your search for a reputable HVAC company are certified technicians. While you may search online and find an HVAC company's website, like, for example, double-check the qualifications that their employees have. Every technician should have NATE certification; or certification in North American Technician Excellence. This certification ensures that they are properly trained in their specialty, which in your case of course will be HVAC systems. You should also look for other certifications, such as BPI specialists for residential sales staff. Comfort Institute members will also demonstrate industry excellence. Most smaller companies do not have actual engineers on staff; having them is an absolute must for any commercial project and will give added assurance that any home HVAC system is of the correct size and can properly heat and cool a residence. It also helps to know if your HVAC company has been around for awhile; established, reputable companies will have certifications while companies that are new and less experienced may not. Look for details on the various certifications that are issued to HVAC technicians in your state. Referrals Don't simply read online reviews when researching an HVAC company. While we don't mean to take anything away from those reviews - they can certainly help lead you to a good company - you will want to be extra thorough in your search since repairing or installing an HVAC system is such a huge project. Try to find a company that has referrals. Talk to friends and family members who have made use of the HVAC company you are interested in; you can also ask local organizations for referrals to reputable companies. If a company gets consistently good references, they are worth considering.


As with referrals, a good HVAC company should be able to provide you with references upon request. If they have consistently satisfied customers, they should have no problem sharing with you a few people you can call. When you do call an HVAC company's references, there are a number of things you should keep in mind to ask. First, ask what the job the company performed. Ask if it was completed on time, and if they kept to the budget. Then, ask how well the job was done. A reputable HVAC company should have glowing reviews from any references they provide.

Home Evaluations

A good HVAC company won't be able to quote you a price until the workers have done a thorough inspection of your heating and cooling system. While many companies will be happy to quote you a cost over the phone, how reliable can this number be if they don't know exactly what type of work you will need done? They will not be able to quote you a proper price if they don't know what type of equipment you have, how old it is, how well-taken care of it has been, and if anything needs to be replaced. A good HVAC company will look at everything that affects the way your system operates; from windows, to ducts, to the heaters and air conditioning units themselves.

Energy Efficiency

Another thing a good HVAC company will have is a knowledge of all the latest in energy-saving technology. When you are redoing your heating and cooling systems, energy-efficient technology can potentially save you thousands of dollars over the years. Less than reputable businesses will often avoid talking about this, as they are not properly trained to install more up-to-date equipment. A top-quality HVAC company may cost more at the outset than a cheaper one, but the savings you will have on your energy bill in avoiding costly repairs down the road will more than make up for that upfront payment. Look for ENERGY STAR products, as they have been certified by the United States Environmental Protection Agency and will help save you money in the long run, as well as being better for the environment. Additionally, homes that have ENERGY STAR certified products often qualify for tax rebates and other benefits.

Licenses and Insurance

A reliable HVAC company needs more than certifications; they should have all of the necessary licenses from your state and local government, as well as all of the insurance and worker's compensation documents. This may seem obvious, but you would be surprised at how many less-than-reputable HVAC companies cannot furnish this documentation. The documents that cover the company should cover everyone, from the management on down to each and every one of the technicians. If a company is unable or unwilling to provide you with this information, you should definitely reconsider making use of their services.

Proper Contracts

As with any big job you are looking to have done in your home, an HVAC contractor should have all the necessary contracts for you to sign. After they have evaluated your home, suggested all of the necessary work and equipment purchases, and given you a quote, they should be able to write all of this into an airtight contract that you both will sign. Having a proper contract will avoid any issues down the road, which is why the less reputable HVAC companies will often try to avoid them. A proper contract will also spell out exactly how the company will receive payment and when; any company that won't tell you this could be attempting to scam you later on.

Stay Local

In most cases, your best bet is to stay local when looking for an HVAC company. For example, companies like Castle Home Comfort based in Illinois are able to service 15 local areas near to their office. You want one with a physical office you can visit so that you can meet with your potential technicians beforehand. They will be able to put any concerns you may have to rest, while explaining fully the type of work that you will need done. You can find more info about them here.
