Heating and Air Conditioning Repair

At Killman Heating & Air, we understand that you can experience problems with your HVAC system at any time of day or night. This is why we respond promptly to repair calls. Our service technicians are qualified to work on all makes and models of HVAC equipment.

HVAC Installation and Replacement

If your HVAC system is beyond repair, turn to our experts for new HVAC installation. We’ll calculate the right size system for your house to make sure it will operate effectively and efficiently for many years to come. We treat your home like it is our home. We’ll also remove your old system and clean our workspace so there is minimal disruption to your home. 

Seasonal Maintenance Visits

Regular maintenance help to keep your HVAC system running at its best, similar to changing the oil and brake pads in a car. Schedule your maintenance services in the early spring and fall to help keep your unit clean and running well. We’ll make minor adjustments and keep an eye out for potential repair issues.

Ductless Heating and Cooling

Not all homes have adequate room to accommodate bulky ductwork. Ductless systems are often a terrific solution in such circumstances. Our experts can help you decide if ductless HVAC is right for your home. If so, we can provide you with a quality installation and any other services you might need.

Indoor Air Quality Improvements

Problems with your home’s air quality can cause a wide variety of health and comfort issues. With our indoor air quality solutions, you can feel better in your home and enjoy fewer asthma and allergy symptoms. We carry and install products that include air purifiers, dehumidifiers, and ventilators.

Light Commercial HVAC Service

Our HVAC services aren’t limited to residential clients. We also have the expertise to help local small businesses keep their HVAC systems running at their best. If it’s time to replace your heating or cooling equipment, our experts can help you select the perfect system for your space and deliver a professional installation.
