Tips

The health of your HVAC system is vital to the comfort inside your home. The HVAC both heats and cools the air to keep the temperature comfortable. It’s located both inside and outside the house which means each portion needs different attention. If you fail to stay on top of maintenance, you’ll experience high energy bills, poor air quality, and a possible system breakdown. Fortunately, these things are avoidable for the most part if you regularly inspect your unit on your own and with the help of a professional. Inspection on your own is preventive. There are small things you can do as a homeowner that will go a long way in energy and financial savings. Hiring a professional HVAC contractor adds to your arsenal. Professionals can come in and ensure that parts are clean, free from obstruction, and working correctly. Unless you are a professional, a little guidance will go a long way. That’s why we created this maintenance checklist. It’s designed to help you know what and how often your equipment needs to be cleaned. We’ve even articulated when you should hire a service professional. The more you know, the better your system will run.

HVAC Components

It’s hard to know how to keep your unit healthy if you don’t understand the different components of your HVAC system. The HVAC system is both inside and outside the home and is comprised of many working parts. Damage to one could lead to problems with another. The below illustration provides you with general information and locations for the different parts. We’ve also listed their function and how they work. This knowledge is essential to the preventive treatment you will need to keep the unit healthy all year long.

Air Duct

Supplies the air throughout the home. Issues with the duct will cause the equipment to overwork and can lead to higher energy bills.

Evaporator Coil

Set your thermostat to use the AC and the evaporator coil kicks in to cool the air. If you experience problems with this component, you won’t have cold air.

Air Handling Unit

The connection between the duct and the hot/cold air is the air handler. It contains the blower and both heating and cooling elements.

Filter

Filters trap particles from clogging the machine. Also, they help maintain healthy air quality. If it’s clogged, you could have issues with various components.

Refrigerant Tubing

Metal tubing connected between the inside and outside unit. They carry the refrigerant needed to bring the air temperature down.

Blower

The blower is the power force needed to push the air into the duct. Once the air is heated, the blower will kick in to get the cycle going.

Fan

Vital to keeping the compressor from overheating, the fan on your outdoor unit pushes the hot air out and away. If they stop, the system could break down.

Compressor/Compressor Coil

The compressor and the compressor coil work in tandem. Their primary function is transferring the refrigerant from inside to outside and back again.

When Should You Inspect Your HVAC Unit?

Knowing when to have your unit inspected will help you save time and money. A few times a year the weather in Middle Tennessee is beautiful, but we can experience hot summers and cold winters. Get your system checked at the recommended time and you won’t experience a hiccup in your service.

Air Conditioning

Once a year, inspect your air conditioning system in the early spring. You want to catch maintenance issues and fix problems before the system starts working in overdrive to keep your home cool.

Heating System

Maintenance checks in the early fall keep your furnace running smoothly. When the temperature dips below freezing, the unit will be primed and ready to keep you and your home warm.
