Why is there a Burning Smell When the Heat Turns On?

It is not uncommon for a burning smell to arise when a central heater unit turns on. It is not always a cause for concern, although there is ample enough reason to look into what’s going on. Here is a look at what a burning smell indicates when a heater is activated.

The cause of the burning smell

When a heater remains stagnant, it is common for a buildup of dust to accumulate. That dust will burn up and while it will not bring any harm, it does give off an odor. This is normal and not a cause for concern. The odor will generally go away within about an hour. If it does persist, then there may be another issue. But don’t be alarmed at the first sign of that smell.

Avoiding the smell

Some homeowners prefer to avoid that burning smell altogether and that can be accomplished. Annual maintenance on a heating system or furnace will complete the process of cleaning the inside of the heater. This can reduce the dust that typically burns up when a heater is activated. There may be a slight smell, but it will be significantly less. It also helps to have a new air filter installed as this is another way of mitigating a burning smell. A filter that is dirty could allow the smell to linger.

When it’s time to worry

There are instances when a burning smell is not a normal sign. If the burning smell persists, then something is amiss. There are several reasons why this occurs. The insulation on the furnace wiring could be melting and this happens when there is an electrical problem. The best solution is simply turning off the heater and calling a professional HVAC repair service.

Other smells that could be problematic

An electrical issue will emit a smell that is similar to burning plastic. This is definitely a cause for concern. If there is a musty smell that is reminiscent of mold, then it could mean that your unit has accumulated too much bacteria. This could be caused by a dirty air filter or a fungus growth on the evaporator coils. And if there is the smell of sulfur or rotten eggs, it means something is amiss with one of your gas appliances. If this happens, leave the home immediately and contact the gas company.

If you experience any of these issues, contact the team of professionals at Air Necessities for the best HVAC service Columbia, SC has to offer.

The Best Air Filters and How Often To Change Them

All air filters are not the same for your AC unit as there are differences every homeowner should know. It is also important to change the air filter regularly as it will improve air flow and quality throughout the home. Here is a look at some helpful hints on air filters and how often they should be changed out.

Air filter varieties

It is important to know the different types of air filters used in HVAC units. The most commonly used filter is the fiberglass variety. It has an appearance very similar to finely woven fabric. There is also a pleated filter available for use and these are woven a little tighter than fiberglass.
Electrostatic filters are considered the best option and elicit a static charge when in use. The charge actually works to trap various types of contaminants.

Changing air filters

It is critical to change out the filters in a timely manner. A fiberglass filter should be changed every one or two months depending on the frequency of use. Pleated filters last a little longer and can go for about six months before changing. There are factors that influence when a filter should be changed and they include usage, location and manufacturer’s instructions.

Benefits of changing filters

There is a long list of benefits that come with regular changing of air filters. It is something that all homeowners can do on their own and helps out in a number of ways. Here is a look at the benefits of changing out an air filter in your HVAC unit on a regular basis.

• Extends life of AC unit – Using a dirty air filter could introduce various types of damage to the unit. This is a form of preventative maintenance that can be done with relative ease. There are other methods of preventative maintenance done by professionals, although this is a simple fix that could pay dividends.

• Enhances air quality – A filter that is clean will ensure that the air that is moved throughout the home will be clean and fresh. This will provide a healthier environment, especially for those who have allergies or any type of respiratory condition.

• Lowers costs – The cost of operating an HVAC system will be reduced because less energy will be used. This could lead to overall energy savings of 10 to 15% on regular cooling bills.

Why it’s Important to Have Annual Service on Your Air Conditioner

Most people take their air conditioning for granted in the summer months. A flick of a switch or push of a button sends cool air whisking throughout a home. But there is a lot more involved beyond just that simple action. Here is a look at why annual maintenance is a major part of ensuring your AC unit works whenever you want to use it.

Energy Efficiency

This is the major buzz word for air conditioners. Having an energy efficient AC unit means you will pay much less every month and that is something every homeowner can get behind. There are subtle adjustments and minor replacements a technician can complete to improve the efficiency of your unit. Annual service also involves a simple cleaning which can go a long way in terms of efficiency.

Improved Air Quality

When an AC unit is not cleaned out regularly, it can become filled with a variety of contaminants. Things like dirt, dander from pets, and dust can accumulate and make its way into the air that runs throughout your home. This can be considered a detriment to your family’s health while clean air ducts will provide excellent air quality for your entire family.

Reduced Repairs

One of the main tasks of annual service is to identify minor issues before they turn into major ones. Preventative maintenance will reduce the overall number of repairs needed on a unit. The type of repair needed during regular maintenance will likely cost less as well.

Increase Life of AC Unit

AC units are not built to last forever, although annual maintenance can keep them operating for as long as possible. Even if that is two or three years longer than normal, that is still two or three more years without having to upgrade to a new unit.

More Reliability

When a professional technician provides annual service, your system just becomes more reliable. That is due to the fact that every working part is checked for reliability. That makes the system function at its most optimum level and can give you peace of mind all summer long.

Enhances Comfort

An AC unit that is not properly maintained could produce higher levels of humidity. There is nothing comforting about coming inside on a hot summer day and quickly feeling all sticky or clammy. Your home should be a place of comfort in the summer months and annual maintenance can go a long way in sustaining that.

What to Expect During HVAC Replacement

Having a new HVAC system installed for a home is something that should not be overwhelming to homeowners. There is a step-by-step process that is followed by formidable HVAC replacement companies. Here is a look at what to expect when you decide on a new HVAC unit.
old HVAC outside unit

Price quote

The first thing a homeowner should expect is to get a quote on how much the replacement will cost. And remember that the lowest price is not always going to provide the best service. Be prepared to know what you are going to pay upfront and make sure there are no hidden fees or unexplained costs.


A price quote should also come with an in-home inspection that includes a load calculation, assessment of ducts, windows, crawlspaces and attics when applicable. This all goes into the process of making the right recommendation for your home. An HVAC technician should ask you a fair amount of questions before making a recommendation as it’s important to get the right model for your home.

Removal of old unit

When removing the old unit, be sure to get an exact quote on how much this will cost and how long it will take. Some HVAC replacement does not need to use all new parts as ductwork could be used from the previous unit. Find out exactly what needs to be removed and you should also receive an explanation for each step in the process.


This is a major type of installation which will need furniture to be moved out of the work areas. A company should also take protective measures and cover the floor so that it does not get damaged during the installation process. There is also no exact time frame for installation. It will depend on the size of the home, unit location, possible ductwork installation and other similar factors.


Once the unit is installed, it should be tested to be sure it is functioning correctly. All the connections need to be double and triple checked. The technicians should show the homeowner all the ins and outs of your new system. This includes maintenance and operation as well as simple procedures like changing out the air filter.

There is a team of professionals in Columbia, SC that will walk you through every step of HVAC replacement. At Air Necessities Heating and Cooling it is our goal to provide top quality service, expert advice and affordable prices.

Ways To Tell If Air Conditioning Is Efficient

You do not have to an HVAC professional to know there is an issue with your air conditioning. There are warning signs that every homeowner can look for in an effort to ensure their AC is running right. Here is a look at some of the easiest and most common ways to tell if your AC unit is as energy efficient as it can be.

Air Conditioner

Same Temperature In Every Room

One telling sign that there is an issue with your AC unit is a fluctuation in temperature from room to room. It is not normal for rooms to have warm or cold spots. This could be a result of poor maintenance or a buildup of dirt and dust in your ductwork. The best way to avoid this type of problem is to maintain your HVAC unit on an annual basis.

No Humidity Throughout House When AC Is On

It’s not difficult to recognize humidity as it provides a warm, uncomfortable feel. It is like a stickiness that should not exist when an AC unit is functioning properly. Efficient air conditioning units are able to control the humidity throughout a home. A unit’s evaporator coils should be cold enough to take all the moisture out of the air before releasing it into the home. When coils are failing or refrigerant is low, the unit has to work harder, thereby reducing its efficiency.

Utility Bills Stay The Same

This warning sign is probably one that every homeowner can identify with as it is definitely eye-catching. A less efficient air conditioning unit translates into an increase in energy bills because the unit has to work harder to cool a home. The summer months will cause an obvious uptick in utility bills but the bills should be relatively close on a monthly basis. When there is a noticeable difference, it’s time to get your unit checked out by a professional.

HVAC Unit Is Near A Decade Old

Age has a lot to do with how efficient an air conditioner performs. There are modern innovations that are infused with new parts, so the availability of higher-quality components has increased greatly from what they were a decade ago. Newer models are just more efficient and for older models to keep pace, they need to be properly maintained. If your unit is around or more than 10 years old, it may be time to upgrade at least some of the parts.

Spring & Summer Energy Savings and Cooling Tips

Spring & Summer Energy Savings and Cooling Tips

With spring in full effect here in the greater Columbia, SC area, summer will soon arrive. Are you still trying to figure out how to ease the strain on your utility bills from the increase in temperature this spring and summer? Good news for you, the Air Necessities Heating and Cooling team is here to help! You can save energy by taking advantage of the warmer weather and preparing your home for the SC heat and humidity. Keep reading below to learn how to cut energy costs this spring and summer while keeping your Columbia, SC home cool and comfortable. 

Reprogram Your Thermostat

If you have a programmable or smart thermostat, it’s important to stay on top of reprogramming it as the seasons change. If your thermostat is still programmed for the winter season, now is the time to change it! Programmable thermostats allow you to schedule the temperature in your home allowing for your HVAC system to operate as efficiently and effectively as possible. This means you can have your thermostat set to its desired temperature while you’re home and let your HVAC system ease up while you’re away.

Use Ceiling Fans Efficiently

During the warmer months, your ceiling fans can be a great help when it comes to cooling off your Columbia, SC home. Running a ceiling fan counterclockwise creates a cooling effect that makes your home feel cooler and more comfortable without having to lower your thermostat. Only turn your fans on if you are in the same room as them and want to ease up on your AC unit while still feeling cool. If used while you’re not in the same room or they are constantly left on, this can actually use more energy than needed which can increase your energy bill. Be sure to use your ceiling fans wisely and efficiently for best results. 

Prepare Your Cooling System

Since your air conditioner will likely need to be used every day this spring and summer, it’s important to make sure that it’s working properly and efficiently before heavily relying on it. It’s important to schedule professional air conditioning maintenance as soon as possible. Maintenance helps to ensure that your AC unit is working properly and will be effective throughout the spring and summer season. If anything is wrong with your cooling system, it’s best to find out now rather than later when you need it the most. 

Keep the Heat Out

Lastly, make sure you are doing everything in your power to keep the heat out of your Columbia, SC home. One thing you can do to ensure heat it kept outside and the cool air is kept inside during the spring and summer is to make sure your insulation is sufficient. Leaky insulation can cause cool air to escape and warm air from the outside enter your home. In addition to making sure your insulation is sufficient, be sure to close your windows and blinds when the sun is the brightest to help prevent the heating effect direct sunlight can have on your Columbia, SC home.

Follow the below tips to help you prepare your air conditioner for the hot and humid weather ahead of us here in the greater Columbia, SC area.

Change Your Air Filters

You’ve heard it before but it can never be said too much, changing your air filters is one of the most important things you can do for your HVAC system. Dirty air filters clog your HVAC system and decrease the quality of your indoor air. This is not only bad for your health, it’s also bad for your air conditioning system since your AC unit has to work harder to compensate for the clogged air filters. We suggest checking them once a month and changing them out once every one to three months. Your home comfort will improve as well as the efficiency of your HVAC system. 

Clean Around Your Outdoor Unit

During the fall and winter months, it’s normal for debris, dirt, and dust to collect on top of your outdoor unit. We suggest cleaning the outside of your air conditioner to prevent any cooling issues this spring and summer. In addition to dusting off your AC unit, it’s important to clear away any plants, bushes, trees, or yard décor that are within a few feet of your unit. Ensuring a clear space around your outdoor unit will keep your AC unit running efficiently and effectively all spring and summer long while keeping your Columbia, SC home cool and comfortable. 

Schedule Professional AC Maintenance

Finally, be sure to call your local HVAC contractor ASAP to schedule professional AC maintenance. Regular heating and air conditioning maintenance is the best and most effective way to take care of your HVAC system.

Or maybe they have a company in mind that they had a terrible experience with. Either way, hearing recommendations from your friends, family, and neighbors is a good place to start your search. 

Read Reviews & Ask for References

Once you have a list of potential HVAC contractors from word of mouth research, now it’s time to add a few more to your list from online research. Online resources such as google, yelp, Facebook, etc. are all great places to go to read reviews. Not all reviews are 100% truthful but the majority of the time, you can get a good idea of what kind of company you are working with. If majority of the reviews are good, you are most likely looking at a good HVAC contractor. The same can be said with a majority of bad reviews – the HVAC company is most likely not great. Do as much research as you want, there are a lot of HVAC companies and reviews to look up!

Ask for Professional Licensing & Experience

Finally, don’t be afraid to ask for license numbers, certifications, trainings, education, and experience. A trustworthy heating and air conditioning shouldn’t have any issue showing you their license number or giving you information on their experience as well as any certifications they have. Ask if their service team does any continuing education or training to better themselves?

How to Avoid a Furnace Emergency This Winter

How to Avoid a Furnace Emergency This Winter

With the cold weather here in the greater Columbia, SC area, we are relying on our heating systems now more than we have been in the past months. As the temperatures continue to drop and get colder, you don’t want to experience a furnace emergency or a complete heating system breakdown in the middle of winter. This can be not only extremely uncomfortable, but also quite stressful for you and your family. To help you prevent a furnace emergency from happening this winter, here are a few things you should do:

Avoid Performing Repairs on Your Own

If you think that your furnace is in need of a quick repair, it’s important to call in the experts for help. Your heating and air conditioning system is a complex system which requires a licensed and experienced professional to inspect it. Avoid performing any kind of furnace repair on your own. Without proper training, you could easily perform the repair incorrectly which could result in your furnace being out more than intended and increase the cost of the repair needed. 

Replace Your Furnace Sooner Rather Than Later

When your furnace gets old, they become less and less energy efficient. In addition, they become more likely to breakdown. If you are unsure how much longer your furnace can last, contact the professionals here at Air Necessities Heating and Cooling to take a look at it.
