Category Archives: Selecting Contractors


You should begin your search for an HVAC contractor with asking friends and associates for recommendations. One of the most important forms of advertising for small businesses is word of mouth. Ask friends if they have used a contractor in the past, who they have used , and if they had a good experience with the company. Contractors are more likely to work harder if they know you have a connection with an existing network they are associated with and that if you do not have a good experience, the news may travel back to the people who gave you the recommendation.

As soon as you have began interviewing contractors, you should make sure to ask several questions to ensure they will provide the support you will need in the future.


How long has the contractor been in business for? You would probably want to chose a contractor who has established a successful track record. An established record provides two benefits. One is the likelihood that the contractor has made their clients more happy than not. Another is that the contractor shouldn’t have any problem providing references who can substantiate a good record.


Always request and check multiple references. A survey 2,000 homeowners, it was found that only 25% of homeowners checked their contractors’ references. These people who did check references were much happier with the ending results. When calling references, be sure to confirm that the hired the contractor in question and whether or not they were satisfied with the contractor’s work. Also, make sure to ask if the contractor finished the project on time and on budget, and if they would willingly recommend this contractor to others. Be aware of references who give lukewarm recommendations, or are unwilling to discuss a contractor. People are reluctant to give bad reference about someone they may work with again in the future.


A reputable contractor will provide a load calculation which take into account many factors that will affect how much heat your home needs. They will need to  come to your home to collect this data to help determine the correct size of the new furnace. Be wary of contractors who don’t perform these calculations, or simply plan to replace the old furnace with the same capacity.


Always be sure a contractor is properly licensed. In the US, HVAC licensing is determined at the state rather than at local or national level. Not all states require HVAC contractors to be licensed and may have a License board, a Contractors Board, or possibly another department will have jurisdiction. It is important to track down the department responsible to find out whether or not your contractor needs to be licensed, or whether they have the appropriate license. You should also check to see if your contractor is properly insured.


Call the town clerk in your city or town and ask if you will need a permit for the work you need done.


People decide to purchase new heating or cooling equipment for all different reasons. They may be selling their current home, and the buyer may have asked that the furnace or air conditioner be upgraded as a condition of the sale. It could be that they are building a new house. The existing equipment may be broken beyond repair, or they may be upgrading their heating or cooling system as an investment to reduce utility bills. Choosing a new furnace or new air conditioner can be an intimidating process no matter what your reason. There are nearly a hundred brands, and thousands of models on the market including high-efficiency models, fully, featured models, and budget models. There are also upflow, downflow, and horizontal models. it is difficult for many to make an informed decision and to make matters worse, you can expect to spend anywhere between $1,000 to $5,000 or more by the time you have your new furnace is installed and working.

People commonly make the decision to let someone else handle all of these choices by calling the first contractor in the yellow pages, provided they find a reputable HVAC contractor by their first call. This can make the process easier, although this is not always the case.

Here is an overview of how the HVAC market works, and how you can identify a reputable HVAC contractor.


Upgrading or installing a new furnace requires the help of a fully qualified and licensed HVAC contractor. This is not a do-it-yourself job and here are some typical steps to follow for selecting a contractor:

1 IDENTIFY and contact at least three or more contractors

2 SET UP an appointment with each of them to visit your home to inspect your current furnace, and collect a wide range of information including how many windows your home has and which direction they face, and how thorough the insulation of the home is, etc. The contractor uses this information to calculate the load, or the correct capacity for the furnace that would be installed in the home.

3 RECIEVE a written estimate from each contractor and make sure it breaks out the different charges that the contractor expects to encounter, including how much the furnace itself will cost and how much for labor and any other work that is recommended.

4 BIDS that are submitted could vary from each of the contractors. If a bid that’s submitted dramatically differs from the other bids, ask the contractor to explain the difference. They may have noticed something the other contractors missed.

5 MAKE SURE the contractor is properly licensed and insured, and ensure the warranties are properly spelled out. You may want to have your lawyer look at your contract. Make sure you get what you think you are going to get at the end of the process.

Some HVAC contractors and companies represent only a single brand or furnace manufacturer and this has its advantages and disadvantages. The contractor has most likely gone through some sort of specialized training offered by the manufacturer. You may have some additional leverage, since you may be able to approach the manufacturer with complaints. If you are getting estimates from a contractor who represents only one brand, be sure to get several other estimates from other contractors to make sure their recommendations are equivalent to the same equipment.

Make sure to ask the manufacturer if they will send a technician to solve any problems if your furnace isn’t working properly after it’s installed. Most manufacturers will expect the contractor who installed the furnace to deal with this issue. This is another reason you should choose a contractor carefully. Although, many people have been able to  appeal to the manufacturer for redress of a concern, usually after quite a bit of persistence.
