Choosing the right contracting company.

When it’s time for a new furnace or air conditioner where do you start? Is there that big of a difference between contracting companies? How do you choose a company that is going to do the best job?

How do you know you are getting the best deal? Is there more value in one company vs. another? Listed below are some of the important things that you should look for when choosing a contracting company that will give the best value for your dollar, both in the short and long term of your investment.

First and foremost is the company licensed and insured, and are they going to pull a permit on your job? This is extremely important for both parties involved in any transaction of this magnitude. Once a permit has been pulled, a city or county inspector must come out and verify that the job has been installed to operate safely, and up to current code requirements. But an inspector can only judge the job by what is visible, and just because it passes inspection does not mean that furnace or air conditioner was installed correctly.

The details that cannot bee seen are what determine how efficiently operate and how long the system will last. This is one corner that must not be cut in order to save money. So to help insure that these details don’t get missed, you want to look for HVAC contracting companies that meet the following criteria:

Does the HVAC company employ NATE (North American Technician Excellence) certified technicians? NATE training put an emphasis on the small and hidden details that go into making a furnace or air conditioner perform properly. When NATE certified technicians are the ones doing the actual work, the odds dramatically increase in your favor that the installation process will end with much better results. The best quality and most efficient furnace or air conditioner available will NOT operate to desired efficiency or last the expected lifespan when the smallest details are missed. This is where a lot of companies will cut corners to save money.

Does the contractor follow ACCA (Air Conditioning Contractors of America) quality installation guidelines? Do they complete a Manual J load calculation to make sure you get the correct size of equipment? Do they evaluate the capacity of your duct work to make sure it is capable of efficiently handling the equipment they are proposing to provide optimum comfort? Here again this goes into the quality of the installation process. Under sizing or over sizing heating and air conditioning equipment are the biggest causes of comfort problems in homes.

Not only do they have to consider the home itself but all of the duct work as well. Corners that are cut during this part of the process to save money be noticed by inefficient operation and short equipment lifespan but also by uncomfortable living spaces. Does the company use sub-contractors or do they have company employees? Here is another place that quality control is difficult to manage and the all important details that can’t be seen are left undone.

Will they protect your home while doing the work? Do their employees wear shoe covers or put down tarps to protect your floors? Clean up all trash and properly dispose of all old furnace or air conditioner? Service after the sale: Many people do not put nearly enough emphasis on this part of the equation. How long has the company been in business? How much longer will the company be in business? Will you be able to reach them if you need them in the future?

Do they offer you guarantees on there work, performance of the equipment, comfort of your home, craftsmanship, etc.? These are all components that go into a successful installation and there are a very limited number of HVAC contracting companies around that can meet them all.

Littleton Heating and Air Conditioning is proud to be able to say that we meet all the above criteria and more. We believe that all of our customers should receive the best possible quality in every one of our installations at the fairest price available.

Why "Manual J Load calculations"

- "Winter Heat Loss and Summer Heat Gain".

Heat gain means during the summer the heat comes into your home thus it's called a gain. During the winter the heat inside your home transfers to the outside thus it's referred to as heat loss. Think about it. Heat always transfers to a colder area, Heat gain for the summer and heat loss for the winter.

Every home should have a calculation done and in accordance with Manual "J" and in accordance with ACCA'S (Air Conditioning Contractor's Association) standards. To be eligible for utility and goverment rebates, and incentives will require this to be done.

Furnace or air conditioner size, (BTU requirement), is based on the type of construction of your home. The insulation it has or will have in the walls or attic, whether the attic is ventilated, The windows single-double-triple pane plus there type, The infiltration of air through your doors, windows, receptacles, ductwork, in general is the home getting above average of infiltration, and how hot or cold it gets in your area. All these things add up to the size of heating and air conditioning unit you must have to maintain your comfort.

Every area has an outside temperature and inside temperature, taken by the hour and season from the weather 10 year average. This is called the Design Temperature. Say a weather 10 year average is 95 degrees outside and a 75 degree inside your dwelling, that would be a 20 degree difference. The air conditioning requirement, (BTU's), would be calculated on it's "Design Temperature" and the grains of moisture.

Sometimes the outside temperature may exceed say the 95 but that is not the normal and your unit is not sized with that in mind. If you sized for the maximum occurrences of less than 1% of the year then you would be oversized at lesser temperatures and could cause a moisture problem.

That's one of the reason's that a larger air conditioner will not remove as much moisture as an undersized unit. A certain amount of running time is very important. When air is discharged from you grille it is very close to 100% humidity level. Think about it, when it rains, (the air is cooled then the moisture (rain) is removed you get 100% moisture level.

Heating does the same thing but in reverse. To dry of air can cause a dryness condition not only for your tongue and groove walls but for you as well may be chapped lips. That's where a humidifier comes into play. Heating also has a design temperature for it's calculation.
