Central Air Conditioning Installation, Replacement, and Repair
Ralph Mann & Sons handles every aspect of central air conditioning for Connecticut homeowners and businesses — new system installation, full replacement of aging equipment, AC repair, and annual maintenance to keep your system running at peak efficiency all summer long. This is not a one-size-fits-all operation. Every project starts with an in-home visit, an honest assessment, and a plan designed around your specific home.
Central air conditioning works by circulating refrigerant between an outdoor condenser unit and an indoor air handler, pulling heat out of your home's air and delivering cooled, conditioned air through a duct system to every room. Ralph Mann & Sons installs, repairs, and services every component of that system.
The repair service covers diagnosis of airflow problems, refrigerant issues, compressor faults, electrical component failures, and thermostat malfunctions. Homeowners who are unsure whether to repair or replace receive an honest assessment during the consultation — not a push toward the more expensive option.
This page covers traditional ducted central air conditioning. For homes without ductwork or rooms that need independent climate control, visit the Ductless Mini-Splits page. For heat pump alternatives to central AC, see Heat Pump / Hybrid Systems.
What Ralph Mann & Sons Delivers
on Every Installation
A new central air conditioning installation from Ralph Mann & Sons is a complete project — from the first conversation to the moment you adjust your thermostat for the first time.
Here is exactly what is included:
Warranty coverage for both equipment and labor is reviewed during the consultation. Ralph Mann & Sons provides AHRI-certified matched system documentation confirming your equipment's rated efficiency and performance.
110 Years of Connecticut HVAC Experience Behind Every Installation

Their team has worked in every type of Connecticut home, from new construction to century-old properties, and they have seen every duct configuration, equipment challenge, and installation scenario the state has to offer.
Ralph Mann & Sons holds a BBB A+ rating (accredited since 2008), NATE certification, AHRI membership, and Connecticut state licenses for heating, home improvement, plumbing, and electrical contracting. They are also affiliated with IGSHPA, GeoExchange, and the Connecticut Heating and Cooling Contractors Association.

Signs Your Central AC System Needs Attention
Central air conditioning systems show clear signals before they fail completely. Catching those signals early is the difference between a straightforward repair and an emergency replacement on the hottest day of the year. Ralph Mann & Sons technicians diagnose the problem first — then recommend the right solution.
Watch for these signs:
Repair or replace? A system over 15 years old with recurring issues or a repair cost that exceeds half the value of a replacement is usually worth replacing. Ralph Mann & Sons gives homeowners a straight answer.
What Changes the Day Your New Central AC System Starts Running
Every room in your home reaches the same temperature. The system manages humidity automatically, so that heavy, sticky feeling that builds up during a Connecticut summer disappears. It runs quietly in the background. You stop thinking about it which is exactly the point.
Upgrading from an older, inefficient system to a new high-efficiency central AC unit can reduce monthly cooling costs by 20 to 40 percent, according to the U.S. Department of Energy. A properly installed and maintained central air conditioning system lasts 15 to 20 years. Ralph Mann & Sons offers annual maintenance programs to protect that lifespan and keep the system running at rated efficiency.

Central AC, Ductless Mini-Splits, and Heat Pumps
Which One Fits Your Home
Not every home needs the same solution. Ralph Mann & Sons installs and services all three systems and helps homeowners choose the right fit based on their home's layout, existing infrastructure, and comfort goals.
| Feature | Central AC | Ductless Mini-Split | Heat Pump |
|---|---|---|---|
| Best for | Whole-home cooling | Room-by-room or no-duct homes | Year-round heating and cooling |
| Ductwork required | Yes (or installed new) | No | Depends on system type |
| Comfort coverage | Whole home, one system | Zone by zone | Whole home |
| Energy efficiency | High (SEER2 rated) | Very high | Very high |
| Ideal scenario | Replacing or upgrading existing system | Additions, older homes, specific rooms | Replacing both heating and cooling |
If your home does not have existing ductwork, that is not a barrier to central AC. Ralph Mann & Sons designs and installs a new duct system as part of the project when the home calls for it.

Central AC Installation Process
Getting a new central air conditioning system installed is a clear four-step process. Ralph Mann & Sons outlines the complete plan — including pricing — before any work begins.
1
In-Home Consultation
A trained technician visits your home to discuss your cooling needs, review any existing HVAC setup, and assess the space — including whether existing ductwork is adequate or a new system is needed.
2
System Design & Proposal
The team completes a Manual J load calculation to determine the precise system size your home requires. They design the duct layout and zone configuration, select equipment matched to your home's needs, and provide complete pricing before any commitment is made.
3
Permits & Installation
The team acquires every required permit and coordinates all municipal inspections with Connecticut authorities — mechanical, gas, and electrical. Licensed technicians complete the installation and integrate your smart thermostat. The home is left clean and the system fully operational the same day.
4
Commissioning and Customer Walkthrough
The team runs full startup testing and safety verification before the job is considered complete. The walkthrough covers how to operate your new system, what maintenance it requires, and the specifics of your equipment and labor warranty.
