Above all else, the right company begins with the measurements. The size of a system must be calculated based on the square footage of your home, insulation, windows, orientation, and infiltration rate. If the system is too large, it will frequently turn on and off, shortening its life; if it is too small, it won’t be able to do the job. Beware of anyone who quotes a system based on the old size.

Then there is the duct system itself, which merits similar treatment. Ductwork that leaks or is inefficient can cause a large portion of the air that your system works hard to produce to be lost, which is why it is necessary for a reputable contractor to inspect the entire system instead of just replacing equipment. The houses in Salt Lake City go through both cold winters and warm summers, and therefore discussing heat pump systems and other alternatives for heating and cooling is worth considering.

Credentials provide some measure of comfort. Find a contractor who is licensed, insured, and certified. Check whether he is a professionally certified contractor, such as one certified by the North American Technician Excellence (NATE).

The owner must demand a detailed and comprehensive written proposal, including the type of equipment, ratio of efficiency, labor done, cost of permits, and overall cost. Contractors provide more than one choice, so the owners can compare cost vs. efficiency. When all of these items are put together in one number, it may require additional questions.

Warranties may be difficult to understand. Equipment usually comes with a manufacturer warranty, while labor warranties come separately and have a different duration, perhaps just two years. The homeowner should find out how long labor warranties are and what they include, as a long manufacturer warranty does not mean much if the cost of labor has to be borne by the homeowner.

Post-installation support is important as well. Does the contractor provide maintenance plans, emergency support, and fast scheduling? A good relationship with one company allows proper maintenance of the system for many years.

The subject of efficiency and cost over time merits mention as well. These units are measured in their annual fuel utilization efficiency rating and seasonal efficiency rating, respectively, which makes the initial investment higher, but could result in savings each month on your electricity bill. Ask about any estimates on operation costs, and if financing is an option should the project be out of reach. Finally, pay attention to how the contractor communicates. Punctual callbacks, clear explanations, and being helpful in answering questions are all good indications, since these traits typically repeat themselves in the process of the work done.

Choosing the best HVAC contractor in Salt Lake City requires some research on your part, but the results will be worth it.
