When the hot summer months approach and you find yourself always standing in front of the fun to keep cool, you dream of installing air conditioning to cool down your entire house.

While it’s not a usually complicated task, it is always good to have a professional HVAC contractor to do the necessary preliminary work and ensure that it is done perfectly. To deliver the efficiency and the cool comfort you are expecting in your new construction, every system installation should include the following standard prerequisites.

1. Sizing

The air conditioning unit must be a perfect match for the particular cooling needs of a custom home in Houston, Texas. The correct sizing does not refer to the physical size of the unit, but to its ability to maintain the cool comfort of your home.

For the perfect results, air conditioning functioning capacity must correspond to the degree of heat the house gains within a similar time span. An undersized air conditioning unit runs virtually continuously as it struggles to meet thermostat settings which may result into high operating costs.

On the other hand, as was mentioned on YouthfulHome.com home improvement journal a larger air conditioning unit with a greater capacity for the home will cycle on and off all the time producing a loud disruptive noise and wasting energy.

2. Efficiency

An air conditioning contractor will do a load calculation taking into account the shape, size, orientation, and the climate of your home to determine the proper unit. The best air conditioning unit should be the least expensive to run and the most energy efficient.

This factor is determined by looking at the EER (Energy Efficiency Ratio) and SEER (Seasonal Energy Efficiency Ratio) ratings of cooling units.

3. Air Sealing and Insulation

The efficiency and cooling performance of an air conditioning unit are directly related to the wholeness of a structure. An HVAC expert may conduct a blower door test to determine the actual amount of air leakage and locate the points of leakage.

Additionally, he will assess the quality of insulation in the attic and inside walls and perhaps advice on the levels according to the current standards of the Department of Energy.

4. Ductwork

Most new homes in Houston, Texas have ducts and vents already installed. However, in few cases, you may need to do ductwork to provide the air conditioning unit with a flow system.

Air Conditioner System Warranties

A newly installed system comes with a warranty which may vary depending on the manufacturer. Generally, warranties vary between 5 and 15 years. It covers the parts and equipment in the machine.

It is also important to learn that there is a contractor’s warranty too. This covers the labor for air conditioner system repairs and any additional work such as wiring the unit to the home, casing the air conditioner in a protective metal among other services.
