It is very important to choose the right heating and air conditioning contractor for your office. For a professional contractor, you don’t only hire him to install the HVAC system; you also want to be sure he knows how to maintain and service it properly. HVAC contractors should be licensed as well as bonded and they should have a complete record of previous work completed and insurance coverage for HVAC. When you hire a contractor, you should ask a few questions so you can get to know him and his companies better.

* How often is your HVAC system serviced? Are there new technicians coming in on a regular basis or do you have a “one-stop-shop” where you get all your services from? HVAC contractors recommend having a technician come in once per year and have the furnace serviced, cleaned and checked on a yearly basis. They suggest scheduling an appointment for the same day each year for an in-house checkup or perhaps every other month. This kind of routine maintenance will ensure that the furnace and ductwork are in good working order.

* How are your heating and cooling system serviced? New technicians usually start by checking the condition of the blower fan and then check the condition of the air ducts. If you do not have your ducts inspected, ask the contractors you are considering to come out and take a look at them. Ask them to identify the problem areas and give you an estimate of what it will cost to make those repairs.

* Are you using a fossil-based fuel or an energy-saving version? Most HVAC contractors recommend an energy-efficient version of HVAC because the older versions were inefficient and used more heat than the newer models. Some contractors may even recommend heating and cooling systems to replace your old heating and air conditioning system with a more efficient model. Before installing a more energy-efficient HVAC, however, you should still ask the contractor to come out and inspect your current system first.

* Are you using a duct system? Most HVAC contractors recommend installing a new, more energy-efficient heating and ventilation system rather than replacing your existing ductwork. Ask the contractor if they would call on their technicians to inspect your ducts and to install a more energy-efficient HVAC.

* Are you getting your air quality certified? Many HVAC contractors offer a free inspection of your heating and cooling system. They would also call on you to go on a tour of their facility to personally witness their certification. Certified air quality should meet the EPA’s Health Safe Air Quality standards.

* Are you using a gas furnace or a natural gas one? Most HVAC contractors prefer to use a natural gas furnace because they believe it has a higher efficiency rating. However, some states have regulations that mandate the use of a furnace that burns oil. Before opting for a new HVAC, you might want to research the pros and cons of each type. Some gas furnaces require special ventilation permits while others are easier to integrate into existing heating and cooling system.

Hiring a good HVAC contractor to work with your existing HVAC system is a very important decision. Do your homework when it comes to choosing a contractor. Be sure to ask how long they have been in business, the services they offer, and how much experience they have with the type of equipment you need to be installed. If you get all the facts before you start working with your HVAC contractor, you will be able to rest assured that your heating and cooling system will be installed properly and efficiently, and no poorly installed system would ruin your home.
