What Proper Installation Gets You

When your AC installation is done right, you get consistent temperatures in every room. No more hot spots upstairs or freezing cold downstairs. No more sky-high electric bills because someone installed the wrong-size system.

The difference between a rushed installation and a proper one shows up in your monthly utility bills. When technicians take time to calculate load requirements and install everything correctly, your system doesn’t work overtime trying to cool your home.

What's Included in Installation

Your AC installation includes proper equipment sizing, professional installation of indoor and outdoor units, and complete system testing. We handle electrical connections, refrigerant lines, and ductwork modifications as needed for your specific home.

Dover’s mix of colonial and contemporary homes often requires custom solutions. We work with existing ductwork when possible or recommend improvements that enhance overall system performance. Each installation includes thorough cleanup and debris removal.

You receive warranty coverage on both equipment and installation work. We also explain your new system’s operation and maintenance requirements. Many customers join our Dempsey Comfort Club for ongoing maintenance that keeps warranties valid and systems running efficiently.

How long does AC installation take in Dover homes?

Most AC installations in Dover take one to two days, depending on your home’s specific requirements. Straightforward replacements where existing ductwork is adequate are typically complete in one day. Homes requiring ductwork modifications, electrical upgrades, or complex layouts may need two days. We’ll give you a realistic timeline during the initial assessment so you can plan accordingly. Weather delays are rare since most installation work happens indoors, but we’ll communicate any schedule changes immediately.

What size AC system do I need for my Dover home?

The right AC size depends on your home’s square footage, insulation levels, window placement, and ceiling heights. Dover’s older homes often have specific characteristics that affect cooling requirements. We perform detailed load calculations rather than using simple square footage rules that lead to oversized systems. Oversized units cycle on and off frequently, wasting energy and failing to remove humidity properly. Undersized units run constantly and never obtain comfortable temperatures. Proper sizing assures efficient operation and consistent comfort throughout your home.

Do I need permits for AC installation in Dover?

Yes, Dover requires permits for most AC installations, especially when electrical work or significant modifications are involved. We handle the entire permitting process, including applications, inspections, and code compliance. Dover’s building department has specific requirements for equipment placement, electrical connections, and refrigerant handling. Using licensed contractors who understand local codes prevents delays and ensures your installation meets all safety standards. We coordinate with inspectors to schedule required visits without disrupting your daily routine.

Can you install AC in older Dover homes without existing ductwork?

Absolutely. Many Dover homes built before central air conditioning became standard can accommodate modern AC systems. Options include installing new ductwork, using existing heating ducts if they’re adequate, or installing ductless mini-split systems. Ductless systems work particularly well in older homes where running new ducts would be invasive or expensive. We evaluate your home’s layout and recommend the most practical solution that provides effective cooling without major structural modifications. Each approach has advantages depending on your specific situation and budget.

What's the difference between cheap and professional AC installation?

Professional installation includes proper equipment sizing, code-compliant electrical work, and thorough system testing. Cheap installations often skip load calculations, use inadequate electrical connections, or rush through testing procedures. These shortcuts lead to higher energy bills, frequent repairs, and premature equipment failure. Professional installers also handle permits, warranties, and follow-up service. We use quality materials and take time to confirm everything works correctly before leaving your home. The upfront cost difference is minimal compared to the long-term problems caused by poor installation.

How do I maintain my new AC system after installation?

Regular maintenance includes changing filters monthly during peak season, keeping outdoor units clear of debris, and scheduling annual professional tune-ups. Our Dempsey Comfort Club provides scheduled maintenance that keeps your system running efficiently and maintains warranty coverage. Professional maintenance includes cleaning coils, checking refrigerant levels, testing electrical connections, and identifying potential problems before they cause breakdowns. Dover’s seasonal temperature swings and humidity levels require attention to both cooling and dehumidification components. Proper maintenance extends equipment life and maintains energy efficiency throughout your system’s lifespan.
