Complete AC Replacement Services

Everything Included, Nothing Extra

Your AC installation includes professional load calculations to ensure proper system sizing. Many cooling problems stem from incorrectly sized equipment, so getting this right from the start saves you money and frustration later.

All necessary permits and inspections get handled as part of our service. Massachusetts has specific requirements for HVAC installations, and navigating those regulations is part of what you’re paying for.

The installation covers new refrigerant lines, electrical connections, condensate drainage, and any ductwork modifications needed for optimal airflow. You also receive manufacturer warranty coverage plus labor warranties on the installation work itself. This gives you multiple layers of protection for your investment.

How long does AC installation take in most homes?

Most residential air conditioning installations take 4-8 hours for a straightforward replacement. If you’re adding central air to a home that previously used window units or upgrading from an older system that requires electrical work, expect a full day. Complex installations involving new ductwork or electrical panel upgrades can take 1-2 days. The timeline depends on your home’s current setup, the type of system being installed, and whether any unexpected issues come up during the work. A good contractor will give you a realistic timeframe upfront and keep you updated if anything changes.

What size AC unit do I need for my home?

AC sizing depends on much more than just square footage. Your home’s insulation, window placement, ceiling height, and even which direction it faces all affect cooling needs. A proper load calculation considers these factors to determine the right capacity. Most homes need between 1.5-5 tons of cooling capacity, but installing the wrong size causes problems. Oversized units cycle on and off too frequently, wasting energy and failing to control humidity. Undersized units run constantly and never reach comfortable temperatures. Professional contractors use Manual J calculations to get sizing right, which is why estimates over the phone or based solely on square footage aren’t reliable.

Can I install a new AC unit myself?

AC installation requires specialized tools, refrigerant handling certification, and knowledge of electrical and mechanical systems that most homeowners don’t have. You’ll need to pull permits, handle refrigerant safely, make electrical connections, and ensure proper drainage. Mistakes can damage expensive equipment, create safety hazards, or void manufacturer warranties. Most importantly, improper installation leads to poor performance, high energy bills, and premature system failure. The money you might save on labor gets eaten up quickly by these problems. Professional installation also comes with warranties on the work itself, giving you recourse if something goes wrong.

When is the best time to replace my air conditioner?

Spring and fall offer the best combination of availability and pricing for AC replacement. You’re not competing with emergency calls during peak summer heat, so contractors have more flexibility with scheduling. However, don’t wait if your current system is showing signs of failure like frequent repairs, rising energy bills, or inability to maintain comfortable temperatures. Emergency replacements during heat waves cost more and limit your equipment options. If your AC is over 10-12 years old and needing repairs, replacing it before it fails completely gives you time to research options and potentially take advantage of rebates or financing offers.

How much does AC installation cost in Massachusetts?

AC installation costs in Massachusetts typically range from $3,000-$8,000 for most residential systems, depending on the equipment chosen and complexity of installation. Basic replacement of an existing central air system costs less than adding AC to a home that never had it. High-efficiency units, ductless systems, and installations requiring electrical upgrades or extensive ductwork modifications cost more. The cheapest option usually isn’t the best value when you factor in energy efficiency, reliability, and warranty coverage. Get detailed written estimates that break down equipment and labor costs, and make sure all necessary permits and inspections are included in the quoted price.

What maintenance does a new AC system need?

New AC systems need regular filter changes every 1-3 months depending on the filter type and your home’s conditions. Annual professional maintenance includes cleaning coils, checking refrigerant levels, inspecting electrical connections, and testing system performance. Keep the outdoor unit clear of debris, leaves, and vegetation that can block airflow. Many homeowners join maintenance programs that include priority service, discounts on repairs, and regular tune-ups. Proper maintenance extends equipment life, maintains efficiency, and catches small problems before they become expensive repairs. Most manufacturer warranties require proof of regular maintenance to remain valid, so keeping up with service protects your investment.
