AC Installation

Installing a new air conditioning system is a major step toward reliable comfort. Proper installation impacts efficiency and lifespan, so careful planning is important. We begin by evaluating your home’s size, layout, cooling needs, and any existing ductwork. This assessment ensures the system you choose will provide consistent airflow and optimal performance while minimizing energy costs. We also help design a zoning system so you can control the different areas of your home. 

During installation, our technicians handle everything from ductwork inspection to equipment setup and calibration. We explain system features like energy-efficient components, programmable thermostats, and multistage compressors so you understand how to get the most from your new system. We can also identify where insulation is lacking and recommend solutions to improve your home's efficiency. 

AC Repair

When your AC stops cooling or starts blowing warm air, prompt, professional repair brings comfort back fast. Our professionals begin with a thorough diagnostic to pinpoint the cause, checking the following:

  • Airflow
  • Thermostat communication
  • Electrical components
  • Capacitors and contactors
  • Condensate drains
  • Coils
  • Refrigerant pressures

Our thorough team addresses common issues such as dirty air filters, mechanical complications, blocked condenser units, frozen evaporator coils, and low refrigerant due to leaks. Before any work begins, you’ll receive a clear explanation of what we found, your options, and upfront pricing. 

Our vehicles are stocked, so many fixes can be completed in one visit, followed by performance testing to verify safe operation and steady temperatures. We also share prevention tips — filter schedules, return vent clearance, and early warning signs — so small problems don’t become big ones. Serving Alpharetta, Roswell, Marietta, and nearby Atlanta neighborhoods, our local team offers convenient scheduling and urgent appointments when available to help you get comfortable sooner, without disrupting your day.

AC Maintenance

Regular maintenance helps prevent surprise breakdowns and keeps energy use in check during North Atlanta’s hottest weeks. Our tuneups typically include: 

  • 93-point diagnostic check
  • Put new batteries in your thermostat
  • Lubricate all moving parts
  • Recalibrate the whole system back to factory specifications
  • Clean the entire system
  • Install a standard air filter
  • Bust the crud in your drip pan — this eliminates odors and stops overflows 

These steps support steadier temperatures, quieter operation, and less strain on components — often extending system life. We will share practical, home-specific tips such as recommended filter types and change intervals, how to keep returns and supply vents clear, and settings that balance comfort with efficiency. Scheduling maintenance before peak heat can reduce midsummer stress and improve reliability. 

During maintenance, we can also spot wear or performance concerns. We will explain what’s happening, your options, and the related costs so you can plan rather than react. Whether your home is in Alpharetta, Roswell, Marietta, or a nearby Atlanta neighborhood, a simple tuneup can go a long way toward comfort, convenience, and peace of mind.

Ductless Split Systems

Ductless mini-splits deliver targeted cooling without the cost or disruption of new ductwork. They're ideal for bonus rooms, sunrooms, older homes, garages, finished basements and home offices in Alpharetta, Roswell, Marietta, and select Atlanta ZIP codes. 

Each compact indoor air handler pairs with an outdoor unit to cool specific zones, so you only condition the spaces you use. Homeowners love the whisper‑quiet operation, precise temperature control, and energy savings that come from eliminating duct losses and dialing in comfort room by room. Our ductless split system service handles everything from sizing and zoning to placement, line‑set routing, electrical connections, condensate management, and clean wall penetrations. 

After installation — usually in just one day — we can commission and test the system, then walk you through filter care, remote or app controls, and simple upkeep. 

When It’s Time for a New Air Conditioner

Even well-maintained air conditioners eventually reach the end of their lifespan. Replacement services evaluate your current system, determine the right upgrade, and install a new unit that meets your home’s cooling needs. We inspect ductwork and electrical connections, remove the old system, and install the new one.

Replacement services focus on efficiency, reliability, and long-term comfort. Our technicians provide clear guidance on system features, operation, and maintenance to ensure homeowners are confident with their new cooling solution. Replacing your AC at the right time keeps your home comfortable, reduces energy costs, and avoids frequent emergency repairs.
