Reliable Cooling That Actually Works

Your old AC system picked the worst possible time to quit. The forecast shows another week of 90-degree days, and you’re already dreading the electric bill from running that ancient, inefficient unit.

A properly installed air conditioning system changes everything. You’ll walk into a consistently cool home every day, regardless of what Massachusetts weather throws at you. Your energy bills drop because modern, correctly sized equipment doesn’t have to work overtime to keep up.

The difference between a quick installation and a professional one shows up in your monthly utility costs and how long your system lasts. When your AC installation is done right the first time, you’re not calling for repairs every summer or dealing with rooms that never quite get cool enough.

Professional AC Installation Process

Straightforward Installation, No Surprises

We start with a thorough assessment of your home’s cooling needs, checking square footage, insulation, windows, and existing ductwork. This isn’t a quick walkthrough – proper system sizing prevents most future problems.

Installation day begins with protecting your floors and furniture. We remove your old equipment safely, install the new indoor and outdoor units, and connect all electrical and refrigerant lines. Every connection gets tested for leaks and proper operation.

Before we leave, we test the entire system under actual operating conditions, show you how everything works, and program your thermostat. You’ll have our contact information for any questions, and we’ll schedule your first maintenance visit to keep everything running smoothly.

Complete AC Replacement Services

Everything Included, Nothing Extra

Your AC installation includes proper system sizing calculations, all necessary permits, professional installation of indoor and outdoor units, electrical connections, refrigerant lines, and condensate drainage. We handle the permit process and ensure everything meets local codes.

Quincy homes often need modifications to accommodate newer, more efficient equipment. We’ll upgrade electrical connections if needed, modify ductwork for better airflow, and ensure proper clearances around outdoor units. Older homes sometimes require creative solutions, and we’ve seen it all.

Every installation comes with thorough testing, system startup, and a complete walkthrough of your new equipment. We’ll explain maintenance requirements, show you how to change filters, and answer any questions about operation or warranty coverage.

Most residential AC installations take 6-8 hours for a complete system replacement. This includes removing the old equipment, installing new indoor and outdoor units, connecting refrigerant lines, electrical work, and thorough testing. Larger homes or installations requiring electrical upgrades might take longer. We’ll give you a realistic timeline during our initial assessment and keep you updated throughout the day. Weather conditions can occasionally affect outdoor work, but we plan installations to minimize any delays.
System size depends on your home’s square footage, insulation quality, window placement, ceiling height, and local climate factors. A system that’s too small won’t keep up on hot days, while an oversized unit cycles on and off too frequently, wasting energy and failing to remove humidity properly. We perform detailed load calculations using industry-standard methods to determine the right size for your specific home. This prevents the comfort and efficiency problems that come from guessing or using outdated rules of thumb.
Yes, most AC installations in Quincy require permits, especially when replacing equipment or modifying electrical connections. We handle the permit application process and ensure all work meets local building codes and Massachusetts energy efficiency requirements. The permit process typically adds a few days to the project timeline, but it protects you by ensuring proper installation and maintaining your home’s compliance with local regulations. Skipping permits can cause problems during home sales or insurance claims.
Energy savings depend on your current system’s age and efficiency compared to the new equipment. Replacing a 10-15 year old system with a high-efficiency unit typically reduces cooling costs by 20-40%. Homes with very old equipment or improperly sized systems often see even greater savings. Modern systems also provide better humidity control, which means you’ll feel comfortable at higher thermostat settings. We can estimate potential savings based on your current system and usage patterns during our consultation.
New equipment comes with manufacturer warranties covering parts and sometimes labor for several years. Our installation work is also guaranteed, so if there’s an issue with our workmanship, we’ll return to fix it at no charge. Most problems with new systems stem from installation errors, which is why we test everything thoroughly before considering the job complete. As Dempsey Comfort Club members, you’ll also get priority service and discounted maintenance to prevent problems before they start.
Yes, we install both traditional central air systems and ductless mini-split systems depending on your home’s layout and your preferences. Ductless systems work well in older homes where adding ductwork would be disruptive or expensive. Mini-splits also allow zone control, so you can cool specific rooms without conditioning the entire house. We’ll assess your home’s structure and discuss the pros and cons of each option to help you choose the best solution for your comfort needs and budget.
