Many people have no idea what the letters HVAC stand for. They stand for Heating, Ventilation, and Air Conditioning. So an HVAC contractor knows a lot about indoor environmental comfort. HVAC system design is a part of mechanical engineering, and it depends on several disciplines that include heat transfer, fluid mechanics, and thermodynamics.
For small buildings and residential homes, contractors usually estimate the capacity in square feet and then select the appropriate size HVAC system. For large buildings it takes a team of mechanical engineers and building service designers to design, and specify the HVAC system. Then specialty mechanical contractors fabricate and commission the HVAC system. So you can see it is much more complicated for large commercial buildings.
You want to be sure that your heating and air conditioning system is properly designed and correctly installed for optimal efficiency. This is because your HVAC system is likely the biggest use of energy in your home. You should receive a free consultation with the contractor or with an HVAC specialist.
They will help you select an HVAC system that is energy efficient and fits in with your lifestyle. It is crucial that your unit is properly sized based on the square footage of your home. A unit that is either too big or too small will not be efficient. Most contractors offer a flexible financing option to help you pay for an installation if needed. Also you should receive factory warranties on your equipment.
A good HVAC contractor will offer a comprehensive service agreement that yoa can sign up for. You will receive regular checkups of your HVAC system in the spring before the summer heat rolls in and again in the fall before the frigid winter temperatures settle in. Service agreement customers benefit from priority service, cash discounts, and extended warranties.
Regular maintenance will extend the life expectancy of your equipment. The service tech can find and fix small problems before they become expensive large problems. These regular checkups will reduce utility bills, reduce repairs, and protect your investment.
