Why would I replace my HVAC system?
Let’s face it: older systems are less efficient than HVAC units put out today. In fact, even a system installed as few as ten years ago could be 60% less efficient than the replacement you would receive. Certain parts for older models are more expensive to replace than simply replacing the entire system. When faced with an expensive repair, it’s good to compare prices. Utility costs can go down with the installation of a new system, and the offset in prices between a replacement part and a new HVAC system could mean it’s cheaper to simply replace the system.
What will be involved in taking the old system out?
Many different parts of the HVAC system will be inspected when the employee comes out to replace the unit or perform the pre-replacement inspection for a quote. These include the ductwork (importance of good ductwork explained in “What happens when the new HVAC system is installed?”), the wires, the thermostat, grills, drain pans, evaporator coils, insulation, piping, flue piping, chimney liners, slabs, and the filter. There are many other pieces that are often inspected, but we are simply making sure that nothing else needs to be replaced or repaired before the new HVAC system is installed in the home.
What happens when the new HVAC system is installed?
It depends on whether or not this is the first HVAC system the house has had. If this is the first system, some items that may be needed include wires, ductwork, and chimney lining. By far, the most important component of the things needed when installing a new system is the ductwork, which is often made of either metal or fiberglass. The duct work must be the correct size to ensure that each room is supplied the right amount of air via the supply duct, and the right amount of air is taken away via the return ducts.
How much will I end up spending on this?
The price is often dependent upon what kind of supplies you’ll need and the quality of the pieces. Condition and type of duct work in the home is something else to take into consideration when thinking about how much to budget for the repairs or replacements. Often, employees will be willing to help you figure out exactly what kind of piece you can purchase on your budget and make sure you get the best quality you can. If you need a thermostat, wires, and some new duct work, it might be worth thinking about installing the new pieces in order of importance: duct work first, and then the wires, then the thermostat. You can budget according to that if need be.
There are so many different HVAC systems! How do I pick the right HVAC unit for my home?
The first thing to consider when picking the HVAC unit for the replacement is to think about the size of the current unit. When receiving a quote for what kind of HVAC would be best, consider asking about other issues too. Will the new unit create any uneven temperature spots from room to room? Would an EMC be a good thing to have, even if I don’t have allergies? (Note that the EMC is used to keep allergens outside for those who have ragweed and pollen allergies, among others, that come from outside). It is also a good idea to make sure you know how much you’re going to end up spending over the lifetime of the replacement. Will the savings from the more efficient unit offset the cost over time, or is it going to end up costing more?
I've had issues with my Indoor Air Quality (IAQ) before. Should I be concerned about that now?
It is worth noting that the EPA (Environmental Protection Agency) has said that exposure to pollutants can be up to 100 times worse inside than outside. However, with newer systems, they are better equipped to protect your home from outside pollutants and keep them outside. They will also help keep the air inside your home from being poluted for as long as they trap the particles in the filters in the HVAC system. Having a system that helps keep the IAQ under control can lead to improved health, even if only by a little.
I've replaced my HVAC system. How long can I expect it to last before I need to replace it again?
The number of years you can expect an HVAC system to last with regular inspections and cleaning can surprise you. An air conditioner should last you between 12 and 15 years while a gas furnace can last between 20 and 25 years. Of course, this is all contingent on whether or not you are taking good care of your HVAC system. As long as the regular inspections, preventative measures, and are making sure any repairs are taken care of when needed are done, you can expect those numbers to be good for your system.
