An HVAC unit is a serious expense. You want to make the most out of the system you have so that you don't need expensive repairs or a replacement. Here are some ways to extend the life of your HVAC system.

1. Clean the Ducts
When you turn the HVAC system on, you need the air to get through to every part of your house. If your home has poor circulation, your HVAC system will need to work harder. Clean the ducts regularly and pay attention if you notice that one room in particular doesn't seem to be getting the same amount of air.

2. Utilize Sunlight/Curtains
Sometimes it's best to use the tools you naturally have at your disposal. One of those things is the sun. Let the sunshine into your home in the winter to help add some natural warmth. In the summer, be sure to shut the curtains to keep the sun out. You can even find curtains specifically designed to keep the sun and its heat out of your home.

3. Use Fans
In the summer, there are more ways to cool off in the summer that don't involve the air conditioner. Try turning a fan on instead of the HVAC system. You should especially consider this if you only need to cool off one little part of your home. The fan doesn't use nearly as much energy, so your bill will be lower. Since the fan is helping cool the home, the HVAC system won't have to work as hard.

4. Clean Around the HVAC System
If your HVAC unit is outside, you want to make an effort to prevent debris from getting caught in the system. This debris can cause it to work harder, get clogged up or even become damaged. Clean twigs and leaves that you find around it. You should also be sure to keep your gutters clean.

5. Get an Automatic Thermostat
It's a good idea to change the thermostat when you leave your home for the day. There's no need to keep the temperature super comfortable when no one is there. The only problem is that it can be hard to remember to do this every day. Let the thermostat remember for you. Buy an automatic thermostat. You can set the days and time you want to change the temperature. You can also set it up to change the temperature back late in the day. Many of these thermostats even let you control the temperature from your phone.

6. Upgrade Insulation in Your Home
Every home has insulation. Insulation is material that goes into your walls to prevent outdoor air from getting into your house. Insulation is generally made out of foam, fiberglass or cellulose. You should also patch up any holes you notice in your home. Get windows that also help keep the outside air out.

7. Clean the Filter
Your HVAC system has a filter. This filter collects the bad stuff that it sucks in. When the filter becomes full, these materials will start to be dispersed throughout the air in your home. This can be bad for your lungs. Breathe in good air by cleaning the filter regularly. Most units have a light to let you know when it's time to clean the filter.

8. Get Regular Professional Maintenance
Call the professionals at Dave Broussard A/C & Heating to schedule an appointment. A professional will perform a tune-up and keep your unit running properly. Schedule your appointment before the winter and summer seasons.

9. Change the Temperature by One Degree
One degree can make a serious difference in your utility bills without drastically changing the temperature in your home. Since you aren't working your HVAC system as hard, it's going to last longer as well.

10. Don't Use the HVAC System
You don't need to use the HVAC system every single day. If the weather is nice, consider opening the windows instead. You can also make a point to wear lighter clothes while in the home.

Using these tips will help you make the most out of your HVAC system. Dave Broussard A/C & Heating does everything from HVAC installation and repair to maintenance in Broussard, LA. We also conduct indoor air quality tests. Contact us to schedule an HVAC inspection today.


Modern gas furnaces have an electronic ignition that starts the burning process. Older furnaces, though, have a standing pilot flame. The pilot flame ignites natural gas entering the furnace, leading to your home being heated. The pilot flame can occasionally go out, requiring it to be restarted. Here are the steps to doing so safely.

Turn Up the Thermostat
Before getting started, turn your thermostat up to a setting that will turn the furnace on. 80 degrees is sufficient. Also, make sure the thermostat mode is set to "HEAT." This will cause the furnace to turn on once you have restarted the pilot light.

Locate the Pilot Light and Controls
Take off your furnace's lower cover. There are two common types of controls. One control method has a gas valve with "Pilot," "On," "Off" and a reset button. The other control method has a knob with "Pilot," "On," "Off" and no reset button, but the knob can be pressed. In either case, turn the control to the "Off" position.

After turning the pilot light control to "Off," you need to wait five minutes before doing anything else. This gives time for any lingering gas to clear away.

Dave Broussard A/C & Heating helps people with furnace issues in the greater Broussard area. If the remaining steps don't fix your furnace, we stand ready to help.

Relight the Pilot Light
You need either a long match or a butane BBQ grill lighter. Turn the control setting to "Pilot." If you have a reset button, push it. If you have the other control system, then press the knob. You can then place a lit match or ignited lighter just above the pilot light, reigniting it.

You'll want to keep the knob or reset button pressed for about 30 seconds. If this doesn't relight your pilot light, repeat the above steps.

No matter how skilled a technician is, repair is not always the best option for a furnace. When the appliance is old, breakdowns become more likely. If you're frequently repairing the furnace, then it probably needs to be replaced. Here are two general rules on how to know whether you should repair or replace your furnace.

Is It Over 15 Years Old?

If your furnace is over 15 years old, you should replace it. An old furnace is likely to break down again after being repaired because of its old age. Furnaces are designed to last 15 to 20 years with good routine maintenance. If the appliance hasn't been tuned yearly, then it might need to get replaced before the 15-year mark.

One of the major problems with an old furnace is higher energy bills. You probably don't want to be surprised one month by your energy bill doubling or tripling. It's best to have the furnace replaced before it begins giving you grief.

Are Repair Costs More Than Half the Price of a Replacement?

If repair costs are more than half the price of a replacement, you should replace the furnace. This is especially true for an old furnace. You don't want to risk having to pay for another repair the following year before having to pay for a replacement shortly after. Many high-quality furnaces come with a manufacturer's warranty. And if you pay for professional maintenance once a year, they are unlikely to need expensive repairs.

It's heating season in Broussard, LA, which means you're likely looking for ways to keep your home comfortable while saving on your energy bill. One of the questions our customers most frequently ask our technicians at Dave Broussard A/C & Heating is whether we recommend allowing their furnace fan to run continuously. Read on to learn whether keeping your furnace fan in the "on" position is an efficient way to heat your house.


The Stack Effect

Hot air is lighter than cold air. Therefore, the heated air in your home naturally rises when the cooler air falls to lower levels. This phenomenon is called the stack effect. Continuously running your furnace fan allows air to circulate throughout your house, thereby balancing the warm and cool air. We offer furnace fan inspection, repair, and installation services to keep your home comfortable.



Impact on Your Electric Bill

You're likely wondering if running your furnace fan continuously will affect your electric bill. If your furnace has an Energy Star rating, it's equipped with a variable speed motor that's designed to run continuously, adding only a few additional dollars to your energy bill. Older models may add an additional $10 to $12 to your monthly heating bill. Over time, running your furnace fan continuously will likely cause your energy bill to decrease as a result of achieving a more consistent desired temperature throughout your house.



Consistent Heating for Single-Story Homes

The stack effect mostly applies to homes that have rooms on more than one level. Nevertheless, you should opt to continuously run your furnace fan if you live in a single-story house. Your residence likely experiences different temperature zones from sunrise to sunset. Operating your furnace fan will provide more balanced heating throughout the day and night regardless of how much sun exposure each room in your home receives.
