Discomfort in the home

The heating and cooling system of your home is very complex. It must be efficient enough to properly cool your home during hot summers and warm it during cold, winter months. The vents are properly placed throughout the home to achieve the most comfortable temperature settings. Additionally, the thermostat allows homeowners to further control the temperature for optimal comfort. It can be difficult to know when to replace your HVAC system. Replacing it can be expensive and an extensive process, so understand the signs that a replacement is needed.

Your homes temperature should be comfortable. It should match your needs. If you find that your thermostat is not achieving your settings, the problem could be with your HVAC system. A thorough HVAC inspection can identify the problem and a recommendation may be made for a full replacement. Sometimes, just your heater or air conditioner may need to be replaced.

It may be especially important to replace your HVAC system if it is not properly heating the home. You may find alternative ways to cool the home, such as with window air conditioners or portable fans, but failing to properly heat the home can result in further damages. For example, extreme winter cold can freeze the plumbing pipes in the home, causing them to burst.

Older system
Just as with all of your homes other appliances, your HVAC system and air conditioners have a time limit. You may need to replace your home?s heating system if it is more than 12 to 15 years old, requires frequent repairs, does not supply sufficient warmth, cycles on and off irregularly, consumes increasing amounts of energy, and emits unusual noises. You will notice that the age of your HVAC unit is the most common cause of replacement.

Higher utility bills
When your HVAC or AC unit begins to not work properly, it produces more energy in an attempt to properly cool or heat the house. The air conditioner, for example, may be on for longer periods of time, without actually cooling the house. This often results in higher energy usage and thus, higher utility bills. If you notice a sudden increase in your home?s heating or cooling bills, it may be time for a HVAC replacement. A qualified HVAC company can determine your utility and energy uses.

One of the benefits of replacing your low efficiency HVAC unit is that HVAC units and air conditioners are made with much higher efficiency ratings today. Furnaces with AFUE ratings between 90% and 95% are considered high efficiency furnaces. These units can cost more up front, but can save money and energy over time and usually have advanced features. With heating and cooling accounting for about 48% of the energy use in a typical home, it is the largest energy expense for most homes and a new unit can significantly reduce the costs.

Constant needed repairs
Even newer HVAC units can require repairs. Although most repairs are required from lack of maintenance, frequent repairs can also indicate that you need a new HVAC unit. Keeping up with preventative maintenance, regular maintenance, and cleanings can prolong the replacement of the HVAC unit. However, once you find that you are regularly calling your experienced electrician out for a service, you may want to consider replacing your HVAC unit.

Funny smells
Considering that your HVAC unit is connected to your air vents, you will breathe in anything that the unit outputs. If you notice funny or abnormal smells from the vents, you will want to have your unit inspected immediately. The smells can be toxic and can be harmful for regular breathing. It can also be an indication that it is time to replace your units.

Most homeowners attempt to prolong the life of their HVAC units. This, however, can be a mistake. Older and poorly functioning HVAC units do not properly heat or cool the home. They also can cause drastic increases in utility bills. Additionally, homeowners may notice that there are funny smells from the unit and that they are regularly calling out an HVAC technician, which can get to be very expensive.
