Some of you may be wondering what HVAC stands for and how it operates in your home. HVAC stands for Heating, Ventilation, and Air Conditioning. It is the machine responsible for keeping your house warm when it is cold and cool when it’s hot outside. It also controls the humidity in your home, keeping unwanted moisture outside and keeping you comfortable. An HVAC system is made up of two components, an indoor and outdoor unit. There are several different types of HVAC units that run on different power sources, but regardless of which unit type you choose, it won’t last forever.
Whether you are prepared for it or not, at some point you will have to replace your home’s HVAC system. Maybe you want something more energy efficient or your system stops working. There is no ideal time to replace your HVAC system, but in this article, we are going to discuss what you can expect when the time comes.
The pre-installation process usually begins when you call us. Unfortunately, most of the time it is because you need a repair that turns into a replacement. HVAC systems have a shelf life and with advances in technology, some parts or refrigerants can no longer be found. We will happily send one of our technicians to inspect your unit and make recommendations for a new unit based on the size of your home and your heating and cooling needs. We will do our best to give you options that fit within your budget. We know this is a large purchase and want you to be informed of your options. Once we start the process, we will schedule a day to remove your old unit and install the new HVAC. The installation date will be based on availability of the equipment. Our goal is to make the transition as seamless as possible so that you won’t have to suffer through uncomfortable temperatures.
HVAC Installation Day
It is finally install day! It could not get here fast enough because that late summer Tennessee heat is getting intense. Something to remember is installation can be an all-day or multiple-day task. Existing equipment must be removed, new equipment is brought in, and adjustments or parts might need to be installed to ensure the new unit fits and runs properly. We might need access to additional areas of your home other than where the HVAC unit will be installed, such as thermostat and registers. Furniture or other items will need to be cleared out of the way. When we arrive, we will review the project with you and check that we have everything needed for the installation. All installation processes can vary, but below is a sample.
- Removal of old equipment. We will disconnect the ductwork, wiring, drain, and gas or exhaust fan (if applicable). Then hook up new ductwork and seal all the connections.
- Hook up new lines and wiring and check for gas leaks. Rework the exhaust vent and gas line if needed. Clean any existing line and replace filters.
- Check the system. Check for any other potential leaks and test the vacuum pressure.
- Add refrigerant and service valves.
- Disconnect and remove the old unit.
- Set and level equipment pad. Set the HVAC unit on risers to protect from snow and other yard debris.
- Install the new unit. This includes connecting any wires, lines, or insulation that might be needed.
Once both parts of the system have been installed, we will test the new unit.
- Pressure and vacuum test are performed.
- Gas pressure (if applicable) is tested.
- Temperature rise—does the temperature rise and lower in your home?
- Check the furnace to ensure it is venting properly.
- Test safety devices that cut the power to the HVAC unit.
- Measure pressure and airflow.
- Add any additional accessories that were added on.
- Charge the unit with refrigerant.
- We will review your system with you and ensure you know how to operate it properly, as well as any problems to alert us to in the future.
Continued HVAC Maintenance
Now that you are comfortable in your home, you should continue some routine maintenance to care for your new unit for years to come. HVAC systems are an investment—you can extend the life of your purchase by taking quality care of it.
- Schedule annual inspections of your HVAC unit. The technician will check filters, fluid levels, wiring, the ductwork, for any leaks, and the surface the outdoor unit is on.
- Replace indoor filters every one to three months based on the dust or pet hair in your home.
- If there are ceiling fans in your home, make sure they are set to a warm or cool setting.
- Keep the area around the units clear of any clutter or debris. Think leaves or plants outside and dust, insulation, or household items inside, especially if the unit is in an attic.
- Check windows or doors for any drafts that might be letting your warm or cool air out.
- Use window coverings to help protect from the glaring sun during summer months.
