If your air conditioner is more than 10 years old, breaking down frequently, or struggling to keep up on hot days, it may be time to replace it rather than keep paying for repairs. Adon Complete Air Conditioning and Heating installs new air conditioning systems throughout McKinney and the surrounding Collin County area. We’ll help you choose the right system for your home, handle the installation from start to finish, and back our work with up to a 10-year labor warranty.
Signs It’s Time for a New AC System
Here are a few things to look out for:
- Your system is over 10 to 12 years old. Most central air conditioning systems last 12 to 15 years with proper maintenance. Once you approach that range, repair costs add up fast, and efficiency drops significantly.
- Your energy bills keep climbing. An aging system works harder to produce the same amount of cooling, which shows up directly in your electric bill. A new high-efficiency unit can substantially reduce cooling costs.
- You’re facing a major repair. If your compressor or evaporator coil needs replacing in an older system, the cost can approach that of a new unit. At that point, replacement is usually the smarter investment. Our AC repair team can help you weigh the options honestly before committing to anything.
- Your home never gets comfortable. If certain rooms are always too hot, no matter what you do, or your system runs constantly without reaching your set temperature, it may be undersized or failing.
What Type of AC System Is Right for Your Home?
There’s no one-size-fits-all answer when it comes to air conditioning installation. We install several types of systems, depending on what best fits the home.
- Central air conditioning. The most common option for homes with existing ductwork. A central system conditions the whole home from a single unit and is the most cost-effective choice for most North Texas homes.
- Ductless mini-split systems. The right choice for homes without ductwork, room additions, converted spaces, or homeowners who want zone-by-zone control. Our mini-split installation service covers single and multi-zone systems throughout the area.
- Heat pump systems. A heat pump provides both heating and cooling from a single system, making it an energy-efficient alternative to separate AC and furnace units. Works well in North Texas’s mild winters.
- Packaged systems. A compact option that houses all components in a single outdoor unit. Common in homes with limited indoor space.
Our technicians will assess your home and recommend the system that best fits your space, budget, and efficiency goals.
Our AC Installation Process
Here’s what to expect when you work with us. We start with a consultation to assess your home, take load calculations to determine the right system size, and walk you through your options before any decision is made. Proper sizing is critical, as an oversized system short-cycles and leaves your home humid, while an undersized one runs nonstop without keeping up.
On installation day, we remove the old equipment, install the new system, connect all electrical and refrigerant lines, thoroughly test the system, and walk you through the new unit before we leave. We don’t consider the job done until you’re fully satisfied.

We install all major air conditioning brands, including Trane, Lennox, Daikin, Mitsubishi, and RunTru. As a Trane Comfort Specialist and Mitsubishi-authorized dealer, we offer factory-trained installation and the full manufacturer’s warranty on every system we install.
