What Proper AC Installation Gets You

Your home stays consistently cool without the constant cycling, humidity problems, or sky-high energy bills that come with poorly installed systems. You get even temperatures in every room, lower monthly costs, and the confidence that your system won’t leave you sweating during the next heat wave.

When your AC is sized and installed correctly, you’re not dealing with short cycling that wears out components early. You’re not calling for repairs every few months. You’re not wondering if today’s the day your system finally gives up when it’s 90 degrees outside.

The right installation means years of reliable cooling, energy savings that actually show up on your bill, and one less thing to worry about during those brutal Norfolk County summers.

How We Handle Your Installation

We start with a proper load calculation to determine exactly what size system your home needs. This process is not based on guesswork or simply replicating the system you previously had. We measure your space, check insulation, evaluate windows, and calculate the actual cooling requirements for your specific home.

Next, we inspect your existing ductwork and electrical connections. If modifications are needed, we handle them before installation day. We protect your floors and furniture, then remove your old system and install the new equipment with attention to proper refrigerant lines, drainage, and airflow.

After installation, we test everything thoroughly. We verify temperatures, check airflow at each vent, and walk you through your new system’s operation. You get warranty information, maintenance recommendations, and direct contact information for any future questions.

What's Included in Every Installation

Every AC installation includes proper load calculations, not estimates based on square footage alone. We evaluate your home’s specific cooling needs, including insulation levels, window placement, and heat sources that affect comfort.

You get professional removal and disposal of your old equipment, plus any necessary electrical or ductwork modifications. We handle permits when required and promote all work that complies with local codes. Our installations include proper refrigerant line sizing, condensate drainage, and thermostat setup.

We clean up completely before we leave. We leave no debris, no damaged landscaping, and no mess for you to deal with. You also receive operation instructions, warranty documentation, and information about our Dempsey Comfort Club for ongoing maintenance and priority service.

Most residential AC installations take 6–8 hours for an upfront replacement. If we’re modifying ductwork, upgrading electrical panels, or dealing with challenging access, it might extend to a full day or require a second visit. We always give you a realistic timeline upfront based on your specific situation. Emergency installations get priority scheduling, and we often complete same-day service when you need cooling restored quickly during heat waves.
The right size depends on your home’s specific characteristics, not just square footage. We perform Manual J load calculations that factor in insulation levels, window types, ceiling height, and heat sources. Most Avon homes need between 2 and 5 tons of cooling capacity, but we’ve seen 1,800 sq ft homes need different sizes based on their construction and orientation. Oversized units short-cycle and create humidity problems. Undersized units run constantly and never reach comfortable temperatures.
Yes, we handle permit applications when required by local codes. Most AC replacements in existing homes don’t require permits if we’re using the same electrical connections and ductwork. However, if we’re upgrading electrical panels, modifying gas lines, or making structural changes, permits are necessary. We know Avon’s requirements and handle the paperwork so you don’t have to deal with town offices or inspection scheduling.
Absolutely. We install both central air systems with new ductwork and ductless mini-split systems, depending on your home’s layout and your preferences. Ductwork installation involves running supply and return ducts through basements, crawl spaces, or attics. Mini-splits offer room-by-room control without ductwork modifications. We evaluate your home’s structure and discuss options that work within your budget and comfort goals.
All our installation work comes with warranty coverage on both equipment and labor. Equipment warranties vary by manufacturer, typically 5–10 years for major components. Our installation labor is warranted for one year. If problems arise, we respond quickly to diagnose and resolve issues. Dempsey Comfort Club members get priority scheduling for service calls and maintenance. We stand behind our work and want your system performing properly for years.
Installation costs vary based on system size, efficiency rating, and installation complexity. We provide detailed estimates after evaluating your home’s specific requirements. Factors affecting cost include ductwork modifications, electrical upgrades, equipment access, and the efficiency level you choose. We explain all costs upfront with no hidden fees or surprise charges. Higher efficiency systems cost more initially but often pay for themselves through lower energy bills over time.
