A properly sized furnace in a Murphy home should complete a heating cycle in roughly 10 to 15 minutes, cycling on and off a few times per hour on a cold January night. When a system runs constantly or shuts off too quickly, it usually points to equipment that was never matched correctly to the house in the first place. Getting that match right is the foundation of every heating installation we perform.

Sizing and System Selection

The first stage of any installation happens before a single tool comes out of the truck. We perform a load calculation based on Manual J standards, which accounts for square footage, ceiling height, window count and orientation, insulation levels, and how tightly the home is sealed. A 2,000 square foot Murphy home with modern insulation may only need a 60,000 BTU furnace, while an older home with single-pane windows could require considerably more capacity.

Oversizing is one of the most common mistakes we correct. A furnace that is too large heats a home in short, aggressive bursts, then shuts down, leaving temperatures uneven and placing extra wear on components. Undersized equipment struggles to keep up during the coldest stretches. Founded in 1978, Bill Joplin's Air Conditioning & Heating has spent decades refining how we match equipment to the specific demands of North Texas homes.

Equipment Options We Install

Murphy homeowners have several heating technologies to choose from, and the right choice depends on your existing infrastructure, budget, and comfort priorities. We install and configure the following types of systems:

• Gas furnaces: The most common choice for homes with existing natural gas service, offering strong heat output and efficiency ratings measured in AFUE, often ranging from 80 to 96 percent.
• Heat pumps: An electric option that both heats and cools, well suited to the mild-to-moderate winters typical of our region and rated by HSPF for heating performance.
• Dual-fuel systems: A pairing of a heat pump with a gas furnace, switching automatically to the most economical heat source as outdoor temperatures change.

Each option carries different technical specifications that affect long-term operating cost. A 96 percent AFUE furnace converts nearly all of its fuel into usable heat, venting very little up the flue. A heat pump with a high HSPF rating moves heat rather than generating it, which can lower energy use during the shoulder seasons when Murphy sees its widest temperature swings.

Our Installation Process

Once the equipment is selected, the physical installation follows a defined sequence that protects both the system and your home. We treat every step as an opportunity to prevent the callbacks that come from rushed work.

1. Removal and inspection: We disconnect and remove the old unit, then inspect the surrounding ductwork, gas line, and electrical connections for any issues that would affect the new installation.
2. Placement and mounting: The new furnace or air handler is positioned, leveled, and secured to manufacturer clearances for safe combustion and airflow.
3. Connections: We complete gas, electrical, condensate, and venting connections, sizing each to code and to the equipment’s rated demand.
4. Ductwork verification: Undersized or leaky ducts undermine even the best furnace, so we confirm the system can deliver conditioned air properly to every room.
5. Startup and testing: We measure temperature rise, check gas pressure, verify safety controls, and confirm the thermostat cycles the system correctly.

This methodical approach matters because a heating installation is only as good as its weakest connection. A perfectly sized furnace attached to leaky ductwork or an incorrectly set gas valve will never deliver the comfort or efficiency it was designed to provide.
