Residential Heating and Cooling Services


Mini-Split Installation

Mini-split systems can provide heating and cooling without requiring the same type of ductwork used by traditional central HVAC systems. They can be a practical option for certain homes, additions, individual rooms, and retrofit projects.

Dot N Sons Heating & Air installs mini-split systems with Wi-Fi capabilities, giving homeowners convenient control over their home's heating and cooling. We also offer advertised flat pricing on select mini-split packages, generally around $2,900–$3,000 installed with Wi-Fi, depending on the project.


Furnace Changeouts

An aging furnace can become a concern when it no longer provides consistent heating or has become inefficient. A furnace changeout replaces the existing unit with a new system that is appropriate for the home.

Dot N Sons Heating & Air provides furnace changeout services for homeowners who are ready to replace older heating equipment. If you are unsure whether replacement is the right choice, a same-day estimate can help you begin evaluating your options.


New AC Installation

A reliable air conditioning system can make a major difference during warm weather. When an existing AC system is outdated or a home needs a new cooling system, professional installation can provide a path toward dependable comfort.

Dot N Sons Heating & Air provides new AC installationsfor residential homeowners. We can discuss your home's needs and help you determine what type of installation is appropriate for the property.


New Construction HVAC

New homes require heating and cooling systems that are considered as part of the construction process. Dot N Sons Heating & Air provides HVAC installation for new construction, helping residential projects establish heating and cooling systems from the beginning.

Whether you are a homeowner planning a new residence or involved in a residential construction project, we can discuss the HVAC requirements and available options.


HVAC Retrofits

An HVAC retrofit involves upgrading the heating and cooling system in an existing property. This can be an option for homeowners who want to modernize an older HVAC setup without treating the project like a new construction installation.

Retrofit solutions can include replacing outdated equipment or introducing newer heating and cooling technology into an existing home. Dot N Sons Heating & Air can help homeowners explore available options based on their property's existing configuration.
