General FAQs

How Can I Maintain My HVAC System?

A:Once you’ve settled into your home or office and are satisfied with your HVAC system, there are certain things that you can do to ensure that your system continues to run smoothly.

Some of the best tips that we’ve come up with over the years are as follows:

  • You should keep your HVAC filter fresh by changing it regularly. Depending on the type of air filter you use, you should change it every one to three months. If you live in an area with a lot of dust or pollution, you may need to change it more.
  • Cleanliness is important. It’s even more important for the outdoor portion of your unit. For any component outdoors, clean away as much dirt and debris as possible, and trim everything around the unit at least two feet back.
  • If you want to save energy (and money), choose a programmable thermostat. Any time you aren’t actively using your HVAC system—whether it’s because you’re sleeping or away from your home—you can allow the temperature to rise or fall depending on the season. If you allow to rise (summer) or fall (winter) by ten degrees for eight hours, you can cut energy costs by as much as 5%-15%.
  • Although you can handle basic maintenance on your own, you should have your HVAC unit serviced by a licensed professional at least one time per year. They can perform more complex tasks like checking combustion in gas and ensuring there are no leaks in your system.
  • If you’re thinking about installing a new HVAC system, ask your HVAC professional to perform Manual J calculations. These calculations ensure that you have the correct system installed in your home or business. If your system is too large or too small, it leads to several complications.
  • Always install carbon monoxide detectors to ensure you and your family’s safety.
  • If you use electricity to heat and cool your home, consider the geothermal option. While these systems cost a little bit more up front, you save money in the long run. They last longer, run more quietly, and use less energy.

What Elements Make a Good HVAC System?

A: A traditional HVAC system is typically made up of four parts: the furnace, the ventilation ductwork, the air conditioning unit, and the thermostat.

The thermostat is the element that helps you control the temperature of your home or business. When talking with a professional in the HVAC business, you want to hear them using the term “indoor air quality” (IAQ). Since a poorly installed HVAC system can cause a lot of problems, you want your professional to be concerned about the air quality to ensure the health of you and other occupants of the building.

ASHRAE, formally known as American Society of Heating, Refrigerating and Air-Conditioning Engineers, considers a building to be suitable if at least 80% of its occupants don’t experience discomfort.

What Are the Major Components of an HVAC System?

A: It’s important for you to have a good idea of what the different elements of an HVAC system are, what they do, and where they are located. A majority of people these days use a central HVAC system that heats and cools and their homes.

These central units are often called “split” systems. The reason for this is that the entire unit is not outside the home. Some components of the system are located inside, while others are located outside. Inside, you’ll typically find the furnace and evaporator portion of the air conditioner (usually in the basement, attic, or a closet). You’ll also find the blower indoors as well. Attached to the blower are the ducts that carry your cool or warm air throughout your home. When you look outside of your home, you’ll find the compressor and condenser for your unit. These are mounted inside a metal cabinet and feature a large fan.

One of the main alternatives to the split system is what is called a packaged system. In a packaged system, the components of your HVAC system are not split between indoors and outdoors. Instead, all of the components are packaged together into one unit that is found outside the home. These units are suitable for people who want to use as much space as possible inside their home.


AC Repairs

Should I Repair Or Replace My Air Conditioning Unit?

A: This depends on the condition, age, and repair estimate of your existing unit. If the cost of repairing your air conditioning system is high ($500 or more) and/or the unit is over 12 years old, you may need to consider replacing it entirely. A new air conditioning unit will be more efficient and reliable, reducing your utility bills. We provide service warranties to cover future repairs.

Are There Any DIY Solutions For HVAC Systems?

A: Sure! You can perform the basic maintenance of your HVAC unit on your own even with some online DIY guides. However, repairing air conditioning units is a sensitive job and should only be done by professionals. Attempting to fix your air conditioning unit could lead to breaking other components.

How Do I Know If My HVAC System Is Working Properly?

A: Normally, your HVAC unit will maintain the temperature of your home at a set point on your thermostat. If your set point is 74 degrees, but your thermometer reading varies by +/- 3 degrees or more, the unit may be malfunctioning. Check for abnormal sounds (clicking, banging, popping, squeaking, etc.) both at the condenser and the furnace. 

Even if the unit is maintaining the indoor temperature of your home, a dirty furnace fan wheel or clogged air filter causes extra-long cycle times and weak air flow which can eventually damage the system – costing you more money in your energy bill and potentially harming your health.

It’s important to shut down the system and schedule repair if you notice your HVAC unit is not working properly. Continued operation can result in costly damages, increasing the cost of repairs.

AC Maintenance

What Regular Maintenance Is Required To Keep My HVAC System Running Properly?

A: Installation of a central air conditioning unit varies with the brand and fluctuates some with the market, though most equipment and their installations cost between $3,000 to $7,000. Always ensure that there are no restricted air flows within your HVAC system. Three common culprits of air flow restriction are dirt, dust, and debris. It’s crucial for both outdoor and indoor units that all filters are cleaned regularly. 

In addition, the coils and heat exchanges must remain clean and clear of any blockages or restrictions. It’s strongly suggested to have your system serviced by a professional twice yearly.

How Often Should My Air Conditioning System Be Serviced?

A: Maintenance of your air conditioning system should be done at least twice a year. During the beginning of spring and about 6 months later. This will ensure that your heating and air conditioning system is prepared to operate efficiently during the summer months. Proper care of your HVAC system will also allow you time to tend to any potential issues with your heat and cooling unit.

Why Is It Important to Replace the Filters Regularly?

A: Changing your air filters regularly is the number one way you can maintain your HVAC system. The air filter is responsible for filtering out dust, pollen, and other particles to maintain high air quality inside the home. Also, when your filter is clogged the blower motor has to work harder to draw the air from your home. A system that’s straining to cool the house means higher energy costs for the homeowner and more wear and tear on the system. This will eventually lead to thousands of dollars in preventable repairs or an early system replacement.

How Often Should I Replace My HVAC Filters?

A: If your system utilizes disposable filters, it’s best to replace them each month. Washable filters also require cleaning each month. These monthly maintenance checks will ensure that your system operates at maximum efficiency. We recommend our AC maintenance service plan where our techs inspect and clean your system twice a year. Part of this service includes servicing the filters. These routine maintenance checks will keep your HVAC system operating smoothly year-round.​

AC Installation

How Much Does It Cost To Install A New Air Conditioning Unit?​

A: Installation of a central air conditioning unit varies with the brand and fluctuates some with the market, though most equipment and their installations cost between $3,000 and $7,000.

What Are The Types Of Air Conditioning Units I Can Install?​

A: Homeowners have many options for air conditioning equipment. The most common type of equipment is a central air system, but some homes require other types of HVAC equipment like ductless mini-split systems or window units.

Are There Any DIY Installation Guides?​

A: We do not recommend you attempt to install an HVAC unit yourself. To conduct an installation safely, special tools, training and education are necessary. A professional installer will guarantee the quality of the job. If you’re not careful, you can damage the equipment and injure yourself.​

How Long Does An AC Installation Take?​

A: A standard installation can usually take between 4 and 10 hours. The complete air conditioner and furnace system installation project ranges from 8 to 14 hours. We aim to complete entire installations in one day.

When Do I Need to Install a New AC System?

A: You should have maintenance inspections scheduled, from which your service provider may recommend a replacement. If you notice any strange noises, smells, or the unit simply doesn’t heat or cool as efficiently as it used to, these may be red flags that you need a replacement unit. If your system is over 12 years old, it’s usually time to think about a replacement.

Heating FAQs

How Does a Heating System Work?

A: The process begins with your furnace, which creates combustion gas. From there, this gas is funneled into a heat exchanger. The unit then takes the air from your home into the exchanger and warms it using the combustion gas. Finally, the air is expelled from the unit to warm your home or office.

Why Do I Need A Furnace Maintenance Contract?

A: Heating is vital to ensure the comfort of your family, employees, co-workers, or anyone else. A working, well-maintained heating unit will also help prevent unhealthy mold buildup caused by winter moisture. Especially with children, excessive exposure to cold temperatures can lead to an unnaturally high blood pressure and heart rate, which could cause many health problems.

How Can I Lower My Heating Bill?

A: When your heating unit is operating, be sure to check that all of your windows, doors are closed. Especially your fireplace vent. You can always try lowering the temperature on your thermostat by a degree or two. The slight drop won’t be too noticeable, and it will benefit your wallet in the long run. If you plan to go on vacation for more than a few days, you could even shut the heater off completely. You’ll also want to make sure the vents are clear of any dust buildup that might prevent heat from blowing out.

What Size Heating System Should I Get?

A: If you’re in the market for a new heating system, it’s important to get one that correlates directly with the size of your home or office. If your unit is too small, it will strain itself trying to heat the whole building. If it’s too large, its cycles will be shorter and more frequent, raising your heating bills. Let us help you choose the right unit today.

How Do I Prevent Damage To My Heating System?

A: Many heating unit dilemmas are the result of dirty filters. Over time, these filters become clogged, which lead to airflow issues throughout the home. Change your filter every 1-3 months. Sometimes dust particles get trapped deep inside the HVAC system; having routine unit maintenance should include deep cleaning of the vents and furnace coils. Another issue is the common wear and tear of the heating system over time. A typical unit will last 10-20 years. If your device is nearing that range, you may need to consider a replacement model.

What’s The Best Temperature To Leave My Thermostat On?

A: Although the answer is up to each person’s preferences, a good range to go by is 65-70 degrees in the winter. However, this is only for when you are inside of your home or office. When nobody’s around, lower the temperature by 10-15 degrees. It won’t impact anyone, and it’ll reduce your heating bill. When you get back, it (hopefully) won’t take too long to get back up to 70 degrees.

Commercial HVAC FAQs

How Much Does An HVAC System Inspection Or Repair Visit Cost?

A: The cost varies depending on your requirements. Call us today to discuss your HVAC problems and we will be able to give you a quote and schedule a visit.

What Is A SEER Rating?
A: SEER stands for Seasonal Energy Efficiency Rating. This ratio tells you high energy efficient your HVAC unit is. The higher the SEER, the more energy efficiency of the unit.
What Is Energy Management?

A: Businesses all over the world are increasingly turning to energy management systems to reduce the cost of heating and cooling their workplace. According to some estimates, over 35% of all US buildings with a surface area bigger than 100,000 square feet use energy management systems.  This helps them save a tremendous amount of money on heating and cooling expenses. Even relatively smaller businesses operating from a medium-sized building can benefit from energy management systems. Simply put, an energy management system allows you to centralize all your energy-related decisions. Centralized timers and sensors are used to better control all heating, cooling, and ventilation systems. A typical energy management system has one terminal to tell you how much energy is being consumed at any point of time and where you could avoid wasting energy. The best part – you can access all these info from any computer using a secure web login.

Are High-Efficiency Commercial HVAC Systems Worth The Investment?
A: Proper heating or cooling a commercial establishment is often an expensive operation. So much so that even a small difference in the energy consumption of your air conditioning and heating units can help your business save a lot on utility bills. Compared to the regular models, high-efficiency commercial HVAC systems can slash a huge chunk of your heating and cooling spending. Sure, they are also more expensive, but the initial investment can be easily recovered in the subsequent months because of substantially lower utility bills.
How Big A Role Does A Commercial HVAC System’s Size Play?
A: The size of an HVAC unit plays a key role on several fronts. If the unit is too small for your office, it will be unable to regulate temperature efficiently during extreme weather conditions. An inefficient system consumes more energy than it should, leading to fatter utility bills, among other issues. Similarly, if the system is too big, it will have difficulty reducing moisture from the air. This could make the air inside the office space humid and uncomfortable for your employees and clients alike!
What Is The Lifespan Of A Commercial HVAC System?

A: A commercial HVAC system requires hefty investment sizing up to several thousands of dollars. Once you spend that kind of money, you can definitely expect your equipment to last as long as possible. The lifespan of a commercial HVAC varies depending on the brand and specs of the layout. However, on average, a well-maintained commercial A/C unit can last up to 10-15 years with the furnace, heat pump, boiler, etc. lasting anywhere between 15 and 20 years.

How Do I Know It’s Time I Replaced My Office HVAC System?

A: If your HVAC unit is more than 5-7 years old and needed excessive repairs in the past couple of years, but with little or no improvement to show for, you should consider replacing it.  Even if you could somehow manage with the older unit by fixing the wear and tear from time to time, we don’t recommend it. Because, the older an HVAC system, the lesser its energy efficiency.  Rather than spending on unnecessary expenses, such as higher-than-normal utility bills and repair charges, it is in the best interest of your company to put that money into a new system.

Why Shouldn’t I Ignore The Regular Maintenance Of My Commercial HVAC System?
A: Most air conditioning manufacturers recommend regular maintenance of your commercial HVAC systems for a reason. Apart from prolonging the lifespan of the unit, regular maintenance also ensures round-the-clock optimal efficiency which is a must for any workplace. Ideally, you should have general maintenance done by experienced professionals at least once a year so they can conduct a thorough cleaning and optimize the system from the inside out. In the absence of regular maintenance, even a minor glitch could turn into a major issue over time and cost your business much more comparatively.

Customer Reviews

“Unbeatable customer service!!! We have just purchased a new house with four units. One of them wasn’t working correctly and I had no idea what to do. I called and spoke with Barrett who came right out and took a look. He knew immediately just by the sound something was wrong, even though the unit wasn’t very old. Barrett then called Kenny and we set up a time to have Kenny come out and run a diagnostic. This was not a unit that Sig Cox had sold or installed, or a brand they usually deal with. Not only did they go above and beyond to do the research and figure out the problem, but Kenny was also able to find out that it was under warranty and saved us over $700!!! He also installed a new thermostat that had been installed incorrectly and wired wrong. Since this was not a manufacturer they normally deal with the part did have to be ordered (which is totally understandable) and Kenny kept apologizing for what was only a one day delay. When the part came in he gave me a call and came right out and installed it. He was very thorough in explaining what the problem was, what he had done to fix it, and taking time to run the unit and making sure it was reaching the proper temperature. I was VERY impressed with high level of professionalism and knowledge these guys have as well as the outstanding customer service they have shown. It is so very rare to find such a remarkable company these days who is far beyond what we now consider to be the “norm”. I will always use Sig Cox from this point on and will recommend them to everyone. Thank you, Thank you!!!”

“I called 6 other companies when my AC stopped pushing air at 5PM. None of them seemed to want my business. When I got to Sig Cox, the guy who answered the phone was polite, knowledgeable, and was even trouble shooting with me before sending someone out. The agent got to my house in 30 minutes, troubleshoot, and fixed the problem in another 30. He even topped off the freon for free. The pricing was definitely agreeable. You’d get charged the same or more with any other company. Some of the best customer service I have seen. You should absolutely consider Sig Cox for you HVAC problems, I won’t be looking anywhere else.”

“Called John regarding an ac issue at a rental property. I wasn’t able to meet them at the house but they worked seamlessly with the renters to quickly identify the problem and resolve the issue. They have been providing inspections and maintenance services for me now for over a year. I really appreciate the high level of support I receive from Sig-Cox.”

“This company did some work for my mother-in-law, of which she was quite pleased, so she recommended them to us. We had a downstairs unit that just wasn’t putting out any cool air. They came by post haste and assessed the unit, gratis. Of course it was a compressor failure so we had to make the hard decision to buy a new unit or fix what we had. The advice we got from our man on the scene was honest and sincere.
Since we had an older unit that used the phased out Freon and compressors are ugh, expensive, we went with a new unit. We decided on the Amana since it had a lifetime warranty on the compressor and rated well in Consumer Reports.
A month later the other unit failed and we replaced that as well. Six Cog worked with us on the price, we were never hassled on the payment, nor did they demand any payment on the spot and never did I feel pressured into anything. The install was smooth, fast and highly professional. Both units fired up, granted a month apart, and the house was cool almost immediately.
This company has a great reputation from what I can garner in the community, and I’m here to tell you that I recommend them highly as well. Please note that this is first recommendation I have ever put online.”

“These people are amazing. After hiring Sig Cox the first time to fix my HVAC unit about a year ago, I was more than happy, to say the least. Then about a week ago I had them install a new HVAC unit for me. This is by far the best a/c repair company in Augusta GA. They are professional, timely, and really take care of their customers. I highly recommend them and proudly give them an A+ rating! Thank you all so much!”

My air conditiong system went out, Sig Cox was recommended so I called them. Technician Andrew came out, was on time, and he properly diagnosed the problem. He had the part ordered. When the part came in, Nolan installed the part perfectly. Both technicians were very professional and knowledgeable. I even talked to the owner of the company who is involve day-to-day with his company. Very nice people to deal and they really go beyond what’s expected to help you get things fixed. I highly recommend Sig Cox!! Ask for Andrew or Nolan, they know what they’re doing!!
