Our Services

Air Conditioning Repair, Replacement and Installation

A cooling system that runs continuously, leaks water, or produces warm air may have mechanical, electrical, or airflow problems. Our air conditioning services in Baltimore County include diagnosing faulty equipment, installing new units, replacing aging systems, and performing seasonal inspections.

AC Repair

A failed capacitor, refrigerant leak, or damaged fan motor can interrupt cooling. We inspect electrical components, refrigerant lines, coils, and thermostat controls to identify the fault and recommend appropriate repairs.

AC Installation

Installing a new air conditioner requires proper equipment sizing and suitable connections. We evaluate cooling demand, insulation, ductwork, electrical capacity, and placement before proceeding with installation for your building.

AC Replacement

Older air conditioners may struggle with uneven temperatures, repeated breakdowns, or increasing energy consumption. We assess existing equipment and discuss suitable replacement units, efficiency ratings, and any necessary installation modifications.

AC Maintenance

Seasonal inspections help identify dirty coils, blocked drains, and worn electrical components. Our technicians examine filters, refrigerant operation, condenser equipment, and drainage systems to identify potential cooling performance issues early.

Emergency AC Repair

A sudden cooling failure can make indoor temperatures uncomfortable, especially during summer. Our emergency technicians investigate urgent air conditioning problems and perform necessary repairs through our 24/7 service availability.

Heating Repair and Installation for Different System Types

Heating equipment can develop problems with ignition, circulation, electrical controls, or airflow. Some faults prevent the system from starting, while others reduce its ability to warm the building. Our heating equipment services cover repairs, installations, replacements, and routine servicing for compatible systems.

Indoor Air Quality and Humidity Control Equipment

Indoor conditions can be affected by airborne particles, moisture levels, and limited ventilation. D&R Home Service offers indoor air quality services involving compatible purification, filtration, humidification, dehumidification, and ventilation equipment for residential and commercial buildings.

Whole-Home Air Purification

Whole-home air purifiers can help reduce certain airborne particles and contaminants circulating indoors. We assess existing HVAC equipment and discuss compatible purification devices, installation requirements, and available filtration options for properties.

Humidifier Installation

Dry indoor air can become noticeable during colder months when heating equipment operates frequently. We assess compatible whole-house humidifiers and discuss installation requirements for managing moisture levels throughout your property.

Dehumidifier Installation

Excess humidity can contribute to condensation, damp surfaces, and uncomfortable indoor conditions. We evaluate moisture concerns and discuss compatible whole-house dehumidifiers that may improve humidity management within the building.

HVAC UV Light Installation

UV-C equipment can be installed in compatible HVAC systems for specific applications. We assess placement options, equipment suitability, and installation requirements for directly illuminated cooling coil surfaces within existing units.

HVAC Air Filtration

Different air filters provide varying particle capture efficiency and airflow resistance. We review existing equipment, discuss suitable MERV ratings, and identify compatible filtration options for residential and commercial HVAC systems.

Ventilation Services

Limited air exchange can allow indoor pollutants to accumulate over time. We review building ventilation requirements and discuss compatible mechanical equipment for introducing outdoor air and removing stale indoor air.
