Complete AC Replacement Services

Everything Included, Done Right

Your AC installation includes proper system sizing, professional installation, and complete testing. We handle permits, disposal of old equipment, and any necessary electrical work to bring everything up to code.

Many Hanover homes built in the 70s and 80s need ductwork modifications or electrical upgrades for modern AC systems. We handle these details as part of the installation process, not as surprise add-ons that inflate your bill later.

You also get access to our Dempsey Comfort Club for ongoing maintenance and priority service. This means your new system stays running efficiently and you have someone to call who already knows your setup if you ever need service.

How long does AC installation take in my Hanover home?

Most residential AC installations in Hanover take one to two days, depending on your home’s setup and whether any electrical or ductwork modifications are needed. Straightforward replacements where existing ductwork and electrical are adequate typically finish in one day. Homes requiring new ductwork, electrical upgrades, or complex installations may need a second day. We’ll give you a realistic timeline upfront based on your specific situation, and we work efficiently to minimize disruption to your daily routine while ensuring everything is installed correctly.

What size AC unit do I need for my home?

The right AC size depends on your home’s square footage, insulation, window placement, and several other factors – not just square footage alone. Many contractors skip this step and just guess based on your old unit, which often leads to problems. We perform proper load calculations to determine exactly what capacity your home needs. An oversized unit will cycle on and off frequently, wasting energy and not removing humidity properly. An undersized unit will run constantly and never cool your home adequately. Getting the sizing right from the start saves you money and keeps you comfortable.

Do you handle permits and inspections for AC installation?

Yes, we handle all necessary permits and coordinate any required inspections as part of your AC installation. Hanover and Bristol County have specific requirements for HVAC installations, especially when electrical work is involved. We know the local codes and what inspectors look for, so you don’t have to worry about navigating the permit process yourself. This is included in our service – you won’t get hit with surprise permit fees or have to take time off work to meet with inspectors. We manage these details so your installation stays on schedule and meets all local requirements.

What happens to my old AC unit after installation?

We remove and properly dispose of your old AC equipment as part of the installation service. This includes the outdoor condenser unit, indoor evaporator coil, and any old ductwork that’s being replaced. Refrigerant is recovered according to EPA regulations, and metal components are recycled when possible. You don’t have to worry about hauling away heavy equipment or finding a disposal facility that accepts refrigerant-containing appliances. The job site is left clean, with old equipment gone and any debris from the installation cleaned up before we consider the job complete.

Will installing new AC require electrical work in my home?

Many AC installations in Hanover require some electrical work, especially in older homes. Modern AC units often need different electrical requirements than older systems, and some homes need dedicated circuits or electrical panel upgrades. We evaluate your existing electrical setup during the initial assessment and tell you upfront if any electrical work is needed. Since we handle both HVAC and electrical work, we can complete everything as part of the same project rather than requiring separate contractors. This keeps the project coordinated and ensures all work is done to code.

How do I maintain my new AC system after installation?

Basic maintenance includes changing filters regularly and keeping the outdoor unit clear of debris, but professional maintenance is essential for keeping your warranty valid and your system running efficiently. Our Dempsey Comfort Club provides scheduled maintenance visits where we clean coils, check refrigerant levels, test electrical connections, and catch small problems before they become expensive repairs. Members also get priority scheduling if service is ever needed. Regular maintenance typically extends system life by several years and keeps energy costs lower by maintaining peak efficiency. We’ll show you what you can do yourself and handle the technical maintenance that requires professional tools and expertise.
