The 411 on Your HVAC System

We know HVAC is confusing, and there are many unknowns when it comes to your heating and cooling. Here are some details to get you up to speed on making the best decisions about HVAC installation in Indiana. 

Factors Impacting the Cost of a New HVAC System

One of the best ways to save on your new HVAC system is to talk to certified dealers like All Pro Heating and Air. We have many resources, rebates, tax credit info, and special promotions happening all the time. 

An additional factor that will determine how much to spend on your unit is the size of your home. Smaller homes will likely only need one unit to keep the home comfortable year-round. Larger homes will likely need two and three systems to ensure they don’t get too cold or too warm in different areas of the house. 

How good are the seals and your windows? This can be an important factor to consider when wondering whether you need a new system. Window and door seals should be installed properly or repaired, so your HVAC unit doesn’t end up running all the time to keep up with the temperature that’s been set. Escaping warm or cool air is a sure way to place too much unnecessary demand on your unit.

Your ductwork matters as well. Did you know that ductwork needs to be designed to fit the needs of your home? This factor will determine the climate in each room and whether or not it’s working in the most energy-efficient way possible. In new home builds, designed ductwork can average about $2000-$3000 depending on the size of your home.

If your home is “difficult,” meaning installers will have to get creative to get the job to work properly, that can impact your overall cost. The trouble with this factor is you might not know about it until the job is underway. Many times these things can be detected early when working with a top-notch crew who can foresee problems and troubleshoot those before that work begins. 

Anatomy of Your HVAC System

FURNACE – A furnace includes four main components. 

  1. A burner that delivers the fuel 
  2. Heat exchangers. 
  3. A blower to deliver warm or cool air. 
  4. A flue that acts as an exhaust of sorts. 

AIR CONDITIONER – An air conditioner transfers heat from the interior of your home and moves it outside. Most homes have what is called a split unit system where an interior evaporating heat exchanger works with a condensing unit heat exchanger located on the exterior of you your home. 

HEAT PUMP –  The heat pump type system is popular among homes in mild climates but can be used anywhere. This is when the system uses outside air to heat or cool a home according to the season. 

AIR HANDLER – A system that uses a heat pump to circulate air throughout the home via an air handling unit. These systems are often used in commercial properties and aren’t as popular for residential customers. Traditional systems usually have all the internal pieces needed that an air handling unit provides when missing the circulating air components. 

DUCTLESS SYSTEMS – Ductless systems are ideal for heating and cooling one room at a time without having to run or design air ducting to and from the unit. Much less hassle for homes that can go that route. 

THERMOSTAT –  Thermostats are placed in two classifications: A traditional stat or a connected control stat. A traditional stat means it can be controlled manually, with some having some programmable options. A control stat can work with other smart features in your home to control the interior climate. 

Maintenance Schedule According to Season

The reason we stress the maintenance of your systems is two-fold. First, a healthy system means you won’t have problems in the middle of the cold tundra! Second, a healthy system will ensure you extend the life of your HVAC unit costing you less overall. HVAC repairs are costly.
