AC Installation Process Whitman

Here's How Your Installation Actually Happens

First, we calculate the proper size unit for your home. This isn’t guesswork – it’s based on your home’s square footage, insulation, windows, and layout. Getting this right prevents most of the problems you hear about with AC systems.

Next, we handle the permits and ensure everything meets local codes. You don’t have to worry about paperwork or inspections – that’s all taken care of as part of the process.

The installation itself is methodical. We protect your floors and belongings, install the indoor and outdoor units with proper clearances, run refrigerant lines, connect electrical, and test everything thoroughly. Before we leave, you know exactly how to operate your new system and what to expect for maintenance.

Most residential AC installations take 6-8 hours for a straightforward replacement, or 1-2 days for new installations that require additional electrical work or ductwork modifications. The timeline depends on your home’s specific requirements and whether you’re replacing an existing system or installing central air for the first time. We provide a clear timeline during the initial consultation so you know what to expect. We work efficiently while ensuring every step is completed properly – rushing an installation almost always leads to problems down the road.
The right size depends on several factors beyond just square footage – including your home’s insulation, window placement, ceiling height, and local climate conditions. A proper load calculation takes all of these into account to determine the correct tonnage for your specific situation. Many contractors skip this step and just estimate based on the old unit or square footage alone, which often results in oversized systems that waste energy and don’t control humidity properly. We perform detailed load calculations for every installation to ensure optimal performance and efficiency.
Yes, AC installations in Whitman typically require permits, especially for new installations or major replacements that involve electrical work. The permit process ensures your installation meets local building codes and safety requirements, which protects you and maintains your home’s value. We handle all permit applications and scheduling of required inspections as part of our installation service. This takes the administrative burden off you and ensures everything is completed properly according to local regulations.
A properly installed system cools your home evenly without excessive cycling on and off. You should notice consistent temperatures throughout different rooms and reasonable energy bills relative to your usage. The outdoor unit should be level and have proper clearance, refrigerant lines should be insulated and secured, and electrical connections should be tight and properly protected. We test all systems thoroughly before completion and provide you with documentation of the work performed, including any warranty information and operating instructions for your new equipment.
Quality installations rarely have immediate problems, but when issues do arise, you want a contractor who stands behind their work. We provide comprehensive warranty coverage on both parts and labor, and our Dempsey Comfort Club members get priority scheduling for any service needs. With over 12,000 customers in our system, we have detailed records of your installation and can quickly diagnose any issues. We’re a local company that’s invested in long-term customer relationships, not just one-time transactions.
Spring and fall typically offer the best scheduling flexibility and sometimes better equipment pricing, since it’s outside peak demand season. However, if your current system is unreliable, don’t wait for the “perfect” time – Massachusetts summers can be brutal, and emergency installations during heat waves are stressful and more expensive. We can often accommodate installations year-round, and our experienced team works efficiently regardless of season. If you’re planning ahead, early spring gives you the most options for scheduling and equipment selection.
