HVAC Systems We Install



  • Split Systems With Furnace and Air Conditioner

    A traditional split system pairs an outdoor air conditioner with an indoor gas or electric furnace. This is the most common HVAC installation for homes with existing ductwork and natural gas service.

  • Heat Pump Systems

    A heat pump system handles both heating and cooling with one outdoor unit and an indoor air handler. Heat pumps are efficient through most Maryland winters and are a strong HVAC installation option for all-electric homes.

  • Dual Fuel Systems

    Dual fuel systems pair a heat pump with a gas furnace. The heat pump runs during mild weather, and the furnace takes over in deep cold, combining efficiency with dependable heat.

  • Ductless Mini-Split Systems

    Ductless systems provide zoned heating and cooling without ductwork, making them ideal for additions, finished basements, garages, and older homes.

  • Packaged Units

    Packaged systems house heating and cooling components in a single outdoor cabinet. They are useful in homes with limited indoor space for equipment.

Our HVAC Installation Process



Load Calculation

We calculate both heating and cooling loads based on square footage, insulation, windows, orientation, and air leakage. Accurate sizing is the foundation of any successful HVAC installation because oversized and undersized systems both waste energy and reduce comfort.

Ductwork Design and Evaluation

For homes with existing ducts, we inspect for leaks, poor sizing, and missing insulation. For new construction or additions, we design duct layouts that deliver balanced airflow to every room.

Fuel, Electrical, and Venting Planning

We confirm gas supply, electrical capacity, and venting requirements for the equipment you select, and identify any upgrades needed before installation day.

Equipment Selection and Pricing

We explain system options at different efficiency levels, covering comfort, humidity control, noise, and operating cost. You receive clear pricing for each HVAC installation option before making a decision.

Installation, Startup, and Testing

Our team installs the outdoor and indoor equipment, refrigerant lines, electrical connections, venting, drainage, and thermostat. We then charge the system, measure airflow and temperature performance in both heating and cooling modes, and complete safety testing on all gas appliances.

Efficiency, Comfort, and Indoor Air Quality



  • Understanding Efficiency Ratings

    SEER2 measures cooling efficiency, AFUE measures furnace efficiency, and HSPF2 measures heat pump heating efficiency. Higher ratings reduce monthly energy use, and we help you balance upfront cost with long-term savings during HVAC installation.

  • Variable-Speed Equipment

    Two-stage and variable-speed systems run longer at lower output, providing more even temperatures, quieter operation, and better humidity removal during Maryland summers.

  • Zoning Options

    Zoning systems use dampers and multiple thermostats to control temperatures in different areas of the home independently, which is helpful in multi-story homes with uneven heating and cooling.

  • Air Filtration and Humidity Control

    HVAC installation is an ideal time to add upgraded filtration, whole-home dehumidifiers, or humidifiers to improve indoor air quality and comfort year-round.

Frequently Asked Questions About HVAC Installation in Upper Marlboro, MD



  • How much does HVAC installation cost in Upper Marlboro, MD?

    HVAC installation cost depends on system type, size, efficiency, ductwork needs, and any gas or electrical upgrades. An in-home evaluation provides accurate pricing for your home.

  • How long does HVAC installation take?

    Replacing a complete heating and cooling system with existing ductwork usually takes one to two days. New construction or projects requiring new ductwork may take longer.

  • What type of HVAC system is best for a Maryland home?

    Split systems with a gas furnace, heat pumps, and dual fuel systems all work well in Maryland. The best choice depends on fuel availability, energy costs, and your home's layout.

  • Should I replace my furnace and AC at the same time?

    If both units are aging, replacing them together ensures matched components, better efficiency, and savings on labor compared to separate installations.

  • What size HVAC system do I need?

    The correct size is determined by a load calculation that accounts for your home's square footage, insulation, windows, and air leakage, not by square footage alone.

  • Do I need new ductwork for HVAC installation?

    Existing ductwork can often be reused if it is properly sized and in good condition. Leaks, damage, or poor design may need to be corrected for the new system to perform correctly.

  • Do I need a permit for HVAC installation in Prince George's County?

    Yes, HVAC installation typically requires mechanical permits and inspection. A licensed contractor handles the process.

  • What is a dual fuel HVAC system?

    A dual fuel system pairs a heat pump with a gas furnace, using the heat pump in mild weather and the furnace during colder temperatures for efficient, reliable heating.

  • Can HVAC installation improve indoor air quality?

    Yes. Adding upgraded filtration, dehumidification, or fresh air ventilation during HVAC installation can reduce dust, allergens, and excess humidity.

  • Are there rebates for HVAC installation in Maryland?

    Qualifying high-efficiency equipment may be eligible for EmPOWER Maryland rebates and federal tax credits. Eligibility should be confirmed before purchase.

  • How long does a new HVAC system last?

    Furnaces typically last 15 to 20 years, air conditioners 15 to 20 years, and heat pumps 12 to 15 years with proper maintenance.
