EXCELLENT Based on 441 reviews Posted on JAMES DODGETrustindex verifies that the original source of the review is Google. Alex was outstanding very friendly and knowledgeable great jobPosted on CRAZY CAT LADYTrustindex verifies that the original source of the review is Google. Tucker came out today for my spring maintenance and he was phenomenal. I have been getting maintenance checks from Zapp twice a year and I haven’t had a tech come out as great as Tucker in years. Tucker took the time after to explain everything to me and show me pictures of everything. Other techs just come and go and I don’t hear a word from them. It’s nice to have someone actually explain what they did and what is going on with my system. I will definitely be requesting Tucker from now on.Posted on JESSICA DOWDLETrustindex verifies that the original source of the review is Google.

Everyone has been wonderful. Today 2/26/24 as scheduled John , Mike , and Caleb did a FANTASTIC JOB, removing our old package unit and installing our New Package unit. They were prompt , knowledgeable, courteous, answered all our questions.They did a great job of cleaning up the area and the new unit is working perfectly.

Looking to replace your HVAC system this season?
It’s a big investment, and understanding what goes into the price can make the decision a lot less stressful. Below, we break down how much an HVAC system should cost, what affects pricing, and how to get a realistic quote for your home so you can plan with confidence.
Our goal is to help you understand your options so you can make confident decisions that keep your home cozy, efficient, and worry-free year-round.
If you’re not sure where to start, you can dive into our “How Much Should an HVAC System Cost?” guide and use our online quote tool to get a ballpark estimate for your home before you ever schedule a visit.
Regular maintenance is key to keeping your HVAC system performing at its best. It helps prevent unexpected breakdowns, supports system longevity, and keeps your home’s air healthier and safer.
Efficiency: A well-maintained system runs smoother, cuts energy waste, and helps lower your utility bills.
Longevity: Cleaning and tuning equipment reduces wear, helping your system last years longer.
Safety: Professional inspections identify electrical issues, clogged components, gas or refrigerant problems, or failing parts before they become hazards.
Comfort: Proper airflow, refrigerant charge, and system settings help reduce hot and cold spots, so your home feels more evenly comfortable in every room.
Fewer Breakdowns: Regular checkups catch small problems early, which means fewer surprise “no heat” or “no cooling” days when the weather is at its worst.
Better Air Quality: Filter changes, coil cleaning, and clearing dust and debris out of the system help cut down on allergens, dust, and musty odors in your home.
Priority Service & Savings (for plan members): Maintenance plan customers get two visits per year plus access to priority scheduling and potential discounts on repairs, making it easier and more affordable to keep everything running smoothly.
For ongoing peace of mind, many Dahlonega homeowners enroll in our maintenance plan, which includes two professional checkups each year—one for cooling, one for heating. During each visit, our technicians clean, inspect, and tune your system, identify early issues before they become expensive problems, and make sure your home stays comfortable through every season.
If you’d like to learn more about what’s included or see if our club membership plan is right for your home, feel free to give us a call. We’re always here to walk you through your options and answer any questions.
If your system is blowing warm air when it should be cool, cool air when it should be warm, making strange noises, or just struggling to keep up, our expert technicians deliver fast, accurate diagnostics and repairs.
We handle both heating and air conditioning repair—from minor comfort issues to major HVAC problems—so you’re not left shivering in the winter or uncomfortable in the summer.
Whether it’s your central air conditioner, heat pump, or furnace, we’ll find the root cause (not just the symptom) and walk you through clear options to get your home comfortable again.
We repair all major brands and tackle issues like:
Frozen coils
Faulty thermostats
Weak airflow or hot/cold spots
Heat pump or AC not cooling
Furnace not heating
System short-cycling or shutting off randomly
From routine AC repair to more complex HVAC system failures, our goal is simple: fix the issue right the first time and restore reliable comfort as quickly as possible.
Evaporator coils are one of the most common places for unwanted buildup inside an HVAC system.
As warm air passes over the cold coil surface, moisture naturally collects—creating an ideal environment for mold, bacteria, and biofilm.
We install a UV light system that shines a safe, continuous ultraviolet beam directly onto the coil area, helping keep it clean and preventing organic growth before it starts.
Our technicians size and position the light for your specific equipment so it actually treats the surfaces that need it most. This keeps your system running more efficiently, reduces musty odors, improves airflow, and helps protect your indoor air quality.
A clean coil also means your system doesn’t have to work as hard, which can extend its life, lower your energy use, and help you get more value out of your HVAC investment.
Indoor air quality plays a huge role in your family’s comfort and health—especially in Dahlonega, where mountain pollen, humidity, and seasonal temperature swings can take a toll on your home’s air.
Dust, allergens, pet dander, mold spores, and even VOCs from everyday cleaners can circulate through your HVAC system and settle inside your ductwork and coils.
Over time, this buildup doesn’t just affect the air you breathe—it can also impact system efficiency and create hidden odors or moisture problems.
We offer a range of indoor air quality solutions designed to keep your home’s air clean, balanced, and healthy. These solutions aim to reduce airborne contaminants, control humidity levels, and improve the overall comfort of your living space.
Our indoor air quality services include:
Whole-home air purifiers
Media filters and high-performance filtration
UV light systems for coil cleaning
Dehumidifiers and humidifiers
Duct cleaning services
Solutions for reducing odors, bacteria, and mold growth
Whether you’re dealing with allergy flare-ups, persistent dust, uneven humidity, or a system that just doesn’t smell as fresh as it should, we can help you choose the right IAQ upgrades to make your home feel cleaner and more comfortable every day.
