AC Installation Process Holbrook

Straightforward Installation From Start To Finish

First, we assess your home’s cooling needs and existing ductwork. This isn’t about selling you the most expensive unit—it’s about finding the right size and efficiency level for your specific situation. We measure your space, check your electrical setup, and recommend options that make sense.

Next comes the actual installation. We remove your old system, install the new air conditioner, and connect everything properly. This includes electrical connections, refrigerant lines, and ductwork modifications if needed. We protect your floors and furniture throughout the process.

Finally, we test the entire system to make sure everything works correctly. You get a walkthrough of your new AC system, including how to operate it efficiently and when to change filters. We don’t leave until you’re completely satisfied with how everything runs.

Everything Included For Proper Installation

Your AC installation includes complete system setup, not just dropping off equipment. We handle permits, electrical connections, refrigerant charging, and ductwork connections. You get a fully functional cooling system ready to handle Holbrook’s summer heat.

We also provide proper system sizing calculations. Too many contractors guess at what size unit you need, leading to short cycling, high humidity, and wasted energy. Dempsey Energy takes the time to calculate your actual cooling load based on your home’s size, insulation, and layout.

The installation includes startup testing and system commissioning. We verify refrigerant levels, test all electrical connections, and make sure your new air conditioner operates at peak efficiency. You also get guidance on maintenance through our Dempsey Comfort Club program to keep your investment protected.

Most residential AC installations take 4-8 hours, depending on your home’s setup and whether ductwork modifications are needed. If you’re replacing an existing system with similar ductwork, the job typically finishes in one day. More complex installations involving new ductwork or electrical upgrades might take longer. We provide a realistic timeline upfront so you know what to expect and can plan accordingly.
AC sizing depends on your home’s square footage, insulation levels, window placement, and ceiling height—not just total square footage. A unit that’s too small won’t cool effectively, while an oversized unit cycles on and off too frequently, wasting energy and creating humidity problems. We perform proper load calculations using industry standards to determine the right size for your specific home, ensuring optimal comfort and efficiency.
Yes, there are several options for homes without existing ductwork. Ductless mini-split systems are popular because they don’t require extensive ductwork installation and offer zone-by-zone temperature control. Alternatively, new ductwork can be installed, though this is more involved and costly. During the assessment, we evaluate your home’s layout and discuss the most practical and cost-effective cooling solution for your situation.
We handle complete removal and proper disposal of your old AC equipment as part of the installation service. This includes safely recovering refrigerant according to EPA regulations, disconnecting electrical and refrigerant lines, and removing the old indoor and outdoor units. You don’t need to worry about disposal fees or finding someone to haul away the old equipment—it’s all included in the installation service.
Most modern AC installations can work with existing electrical systems, though some upgrades might be needed depending on your home’s age and current setup. Older thermostats may need replacement to properly control new, more efficient AC systems. During the initial assessment, we check your electrical panel capacity and thermostat compatibility, explaining any necessary upgrades upfront so there are no surprises during installation.
Regular maintenance keeps your new AC running efficiently and extends its lifespan significantly. This includes changing filters regularly, keeping the outdoor unit clear of debris, and scheduling annual professional tune-ups. We offer our Dempsey Comfort Club membership program, which includes regular maintenance visits to keep your system in top condition. We’ll also explain basic maintenance tasks you can handle yourself to keep everything running smoothly between service visits.
