Heat Pumps
Heat pumps are one of the most popular and efficient HVAC systems available today. They work by transferring heat rather than generating it, allowing them to cool your home in the summer and heat it in the winter. They are the most common system that we install, and for good reason.
Pros:
- Energy Efficiency: Heat pumps are extremely efficient, especially compared to traditional systems. This can lead to lower monthly energy bills.
- Heating & Cooling In One System: You get year-round comfort without needing a separate furnace.
- Environmentally Friendly: Because they use less energy, heat pumps reduce your carbon footprint.
Cons:
- More Expensive To Install: The upfront cost can be higher than traditional AC systems, though rebates and tax credits can help offset the cost.
Central AC Systems
Central air conditioning systems are a traditional and reliable way to cool your entire home using ductwork. They used to be the standard before heat pump technology became more popular, but we still see some homes with them around our area.
Pros:
- Whole Home Comfort: Central AC systems distribute cool air evenly throughout your home.
- Environmentally Friendly: Modern systems are much more efficient than older models and use improved refrigerants.
Cons:
- Cannot Provide Heating: You’ll need a separate heating system, like a furnace or heat pump.
- Not As Efficient As Heat Pumps Or Mini Splits: While efficient, they typically don’t match the performance of newer technologies.
Ductless Mini Splits
Ductless mini splits are becoming increasingly popular for their flexibility and efficiency. We see these more and more in homes and businesses, and are perfect HVAC solutions for a few different reasons. These systems consist of an outdoor unit connected to one or more indoor air handlers. Their ease of installation and lack of a need for ductwork has made them one of our favorite systems to install.
Pros:
- Energy Efficiency: Ductless systems are highly efficient and avoid energy loss through ductwork.
- Heating & Cooling: Like heat pumps, they provide both heating and cooling, giving you year-round comfort.
- Environmentally Friendly: Lower energy use means less environmental impact.
- Zoned HVAC: Each unit operates independently, allowing you to control temperatures room-by-room.
- No Ductwork Required: Perfect for older homes, additions, garages, or bonus rooms. Ductless mini splits are a great supplemental option for homes with perfectly working cooling systems, but need to provide some comfort for that addition!
Cons:
- Expensive To Install: Initial costs can be higher, but rebates and incentives are often available to reduce the investment.
Window Air Conditioning Systems
Window AC units are a simple and affordable option for cooling individual rooms. Almost everyone has seen one or used one at some point, and you probably already know some of the pros and cons. They are simple, cheap, and easy, but there is usually a reason for that.
Pros:
- Immediate Cooling: Quick and easy way to cool a space.
- Cheap To Install: Lower upfront cost compared to whole-home systems.
- No Ductwork Needed: Ideal for small spaces or temporary solutions.
Cons:
- Very Noisy: Can be disruptive, especially in bedrooms or living areas.
- Energy Wasters: Often lead to higher energy bills due to lower efficiency.
- Take Up A Window: Blocks natural light and outdoor views.
- Uneven Cooling: Typically only cools one area and struggles to distribute air evenly.
Choosing The Right AC System For Your Home
Each type of air conditioning system has its place, and the best option depends on your home, budget, and comfort goals. In most cases, we like to suggest the heat pump or ductless mini split system. These are going to provide year round comfort, and operate the most efficiently, leading to lower energy bills.
- Looking for maximum efficiency and year-round comfort? A heat pump or ductless system may be your best bet.
- Have existing ductwork and want a straightforward solution? Central AC or a heat pump could be a great fit.
- Need a quick, low-cost fix? A window unit can help in the short term. We don’t recommend this as a long term solution.
- Need HVAC for an addition, garage, or sunroom? We recommend a ductless mini split. No ductwork is needed and they can provide year round heating and cooling.
At Complete Comfort, we take the time to evaluate your home and recommend the best solution for your needs, not just the most expensive one.

Let’s make sure your home stays cool and comfortable all summer long.
In the past few years,
Your HVAC system has likely been working hard all winter long. A dirty air filter can restrict airflow, lower efficiency, and make your system work harder than it should. Changing it is as simple as removing the old filter, and replacing it with a fresh one.
The number one thing we recommend you do to get the most out of your HVAC system is to schedule routine maintenance. Spring is the perfect time to schedule air conditioning maintenance before the heat makes its way in.


The short answer is yes, a generator does need to be serviced, preferably once a year. If you have a whole-home generator, it sits outside and remains dormant most of the time. Every now and then, it will kick on if the power goes out, but for the most part, it’s not used unless it’s needed. For this reason, it can often go overlooked when it comes to scheduling regular maintenance. 
During the coldest months of the year, like we are experiencing right now, there can be challenges keeping every space in a home comfortable. Maybe it’s a single space, or an entire floor in your home. For homes and businesses in our area of Smyth County, Abingdon, Bristol, etc., we can see some brutal weather. It’s not unusual to have a room or a space that never seems to stay comfortable.
If you have a vented system like a furnace that uses ductwork, which is most common in our area, then there could be an issue with that heated air getting to every space in the home. With a system like this one, your furnace produces heat, and then it’s pushed through your vents. Most commonly, bedrooms and spaces that are furthest away from the furnace have been the problem areas.
It’s officially 2026, and now is the time of year when people make resolutions to improve themselves and their lives. This is usually some sort of plan to start working out more and dieting. It could also be finding a new career path, or completing a long-standing project. Well here at Complete Comfort, we specialize in home comfort, home power, and indoor air quality. In this article, we want to focus on some resolutions that will protect and improve your home!
In our area of Virginia and Tennessee, we have seen some NASTY weather in the past few years. Installing a standby generator is a great way to ensure your home has power no matter what the weather is like outside. Instead of losing power for days on end, a standby generator kicks right on and supplies your home with electricity.
Changing your air filter is a simple process, but an important step in making sure the air in your home is clean and the HVAC system is running smoothly. Unfortunately, it’s often a task that goes overlooked or forgotten, and can lead to problems.
Replacing your air filter keeps the air in your home clean and also helps promote better airflow. The purpose of your filter is to catch any particles that may be floating in the air. Dust, allergens, bacteria, mold spores, and more are floating around the air, and with a dirty filter, it will fail to prevent them from passing through.
