Hvac Installation Cost

Before we talk of the cost of installing a HVA c system in a house, we should first take into account the factors that require consideration. All the factors together will decide the cost of installing a HVAC unit.

First of all HVAC systems can be broadly divided in to two categories - Roof-Mounted HVAC and Split HVAC.

In roof mounted systems both the heating and cooling components are present in one cabinet. They are also called "gas packs" if your heater is using natural gas to heat up the house. They are quite difficult install. You should have proper space in the roof to place them. The space should also be able to support the weight of the unit. A platform is built on the roof to place it. A drain pipe for the unit must be run along the roof to prevent it from corroding. Usually a crane is used to lift the unit on the roof top. Once placed on the roof, a team of installation workers work together to install it.

The spit HVACs are more efficient than roof top counterparts. Here the two components for heating and cooling are separated from each other. Installing a split system can require some changes to be maiden the house for the necessary lines to be run.

The size of the unit is very important for efficient cooling. Do not buy a big system it will not make you more comfortable as the popular notion goes. It will often cycle and off and start again. This will lead to steeper utility bills. It will drain the rooms completely of humidity, thus giving you a damp feeling. Frequent on and off will also produce greater wear ad tear of the machine. Mark, in order to ensure that both temperature and humidity are at perfect levels, an HVAC system should run for around 30 minutes at a time. On the other hand if you buy too small a system it will run too long,each cycle.

A very easy calculation will help you compute the size of the HVAC needed for your house. A rule of thumb is 20 BTUs per square foot. So, a 1000 square foot room would need 20,000 BTUs to cool or warm it efficiently. This formula assumes that you have foolproof insulation and you live in a moderate climate. However speaking practically, all units have some degree of energy loss.

You can opt for both single-staged and multi-staged system. A single-staged system has one speed that is designed for maximum comfort. They run in full speed even in seasons when they don’t have to. The multi-staged ones have more than a single speed. They adjust speeds according to needs. These cost more upfront but help in energy saving in the long run.

You can also buy HVACs with zoned systems. These machines will heat and cool rooms that need it. Dampers in the ducting block airflow in rooms that are not in use. They divert the airflow only to occupied rooms. This is also an energy saver. It will pile up the cost even more if you want to buy a separate humidifier and a second-stage filter. The latter is very useful to remove pet dander from your indoor air. It will effectively remove aerial contaminants from the air you breath indoors.

The duct is very important part of a HVAC system. If you are just replacing an older HVAC system with a new one then you do not need to make new ducts for it. All you need to do is check it for repairs. But if you have to make new ducts then it is a big job. It will almost double up the installation cost. The installer will need to decide the size and design of the duct based on the dimensions of your house. Calculating the duct size is a very important and a critical job. It includes a whole lot of calculations. A properly sized duct will ensure that the air is being efficiently circulated throughout your home. Besides ducts you also need vents in the right places which will send out and take in air from the rooms. Vents can be placed in ceilings or in floors. As for floor vents you have to keep in mind that these are not getting guarded by carpet or furniture. Blocked vents will not cool rooms effectively. The duct and vents of a house play a very effective role in giving perfect cooling comfort. All ducts lose2% to 5% of your energy. However if there is a leakage in the duct almost 50 % of the conditioned air will be lost to the surrounding. Before installing the HVAC, the contractor should carefully inspect the ducts for leakage and other damages. These should be mended immediately. Sometimes if your new unit has a different size to your old one, your ducts will also require to be remade.

Wiring the thermostat is also a part of HVAC installation. It is not a critical job but the thermostat need to be placed in a proper place so that the sensors are exposed for an accurate reading of the temperature. If it gets blocked by any furniture then it will not get a good reading and will not perform efficiently.

There are various types of thermostat. For instance, the manual ones of yesteryear, they are not considered efficient today. But they do not need batteries to be changed every month. Programmable thermostats are more efficient than manual thermostats. You can schedule temperatures for particular phases of the day or week. Say, for instance, in summer you can set it to stay off till you are in the bed. It will start to cool the house, when you get up along with other members and move around the house. In winter you can program it to shut off when you are away from the house. It can be set to start an hour before you reach home. By that time the temperature inside will become comfortable. You can adjust these thermostats from remote locations with mobiles apps or web applications.

The factors that we discussed will boost he functionality of your HVAC. But having them will increase your buying and installation charges. On an average a for a 1,000 square foot home, the cost of an HVAC system is $6,000 to $12,000. This will include a new air conditioner, a new furnace, and laying new duct work. For bigger homes with complex design, the charges will shoot up. If you only want to replace the air conditioner of your HVAC then you will need to shell out $3,000 to $5,000 for a 2,000 square foot home. In case of a furnace it will be around $2,500 to $7,500 or more. However if you do not need ducts to be made, just installing the system will do, then the cost could be between $1,000 and $3,000.

Tax rebates were available for buying HVACs. Unfortunately, federal tax credits were stopped in 2013 for residential units. State governments can offer you tax rebates if you buy high –efficiency systems.
