Phase 1: Pre-Installation Preparation – Setting the Stage for Success
Proper installation starts well before our crew arrives. This phase lays the foundation for years of reliable comfort, and the decisions made now will ensure a smooth process.
Choosing the Right System: Sizing and Type
Many homeowners mistakenly believe bigger is better when choosing a furnace. In reality, the right size is the only size that matters.
Proper furnace sizing starts with a Manual J load calculation. This involves precise engineering that considers your home’s square footage, insulation, windows, occupancy, and the local Texas climate. The ACCA Manual J standards guide this process to perfectly match the furnace to your home.
An oversized furnace will short-cycle, wasting energy and wearing out parts faster. An undersized furnace will run constantly trying to keep up, leading to high bills and premature failure.
When choosing between gas and electric furnaces, your home’s setup and local energy costs are key factors. Gas furnaces are a great choice in McKinney and Collin County, where natural gas is available. They typically cost less to operate and handle our cold snaps well. Electric furnaces can be highly efficient, but monthly bills depend on local electricity rates.
You’ll also hear about SEER2 ratings for newer systems, which help you understand energy efficiency. If you’re wondering whether your current system is ready for retirement, check out our guide on Signs Its Time for a Furnace Replacement.
Getting permits and scheduling your installation is part of our service. McKinney, TX, and most of Collin County require mechanical permits (and sometimes electrical or gas permits) to ensure installations are safe and up to code. We handle all the necessary paperwork and filing for you.
Once the paperwork is sorted, we’ll schedule the installation. Most replacements take four to eight hours, and we’ll provide a specific timeframe for your situation.
Homeowner’s Pre-Installation Furnace Installation Checklist
Your preparation helps ensure a smooth installation day:
Clear the work area around your existing furnace. We need at least five feet of clearance on all sides for installation and future maintenance.
Create a clear path from the entry to the furnace location. We’ll be carrying heavy equipment, so a clear path prevents damage and helps us work efficiently.
Secure pets and children for their safety. Please keep them away from the work area, tools, and equipment.
Plan for parking if you have preferences. A heads-up about any parking quirks helps us be better neighbors.

Key Steps in a Professional Furnace Installation
Installing your new system involves several key steps from our furnace installation checklist designed for safety, efficiency, and reliability. For a comprehensive look at our process, visit our Key Steps in Furnace Installation page.
Placing the new unit requires precision. The furnace must sit on a solid, level surface with at least five feet of clearance from combustible materials for safety and proper air circulation.
Electrical connections are made according to the National Electrical Code (NEC) and local regulations. We secure all wiring, ensure proper grounding, and seal electrical openings to prevent air leaks.
For gas furnaces, the gas line connection is critical. We connect supply lines with meticulous attention to detail, install a drip leg (sediment trap), and perform comprehensive gas leak testing.
Venting and flue pipe installation ensures the safe expulsion of combustion byproducts. We install the flue pipe with the correct slope and clearances and seal all ductwork connections to prevent carbon monoxide leaks.
High-efficiency condensing furnaces require a condensate drain line, which we install with a trap and overflow safety switch to prevent water damage.
Finally, thermostat wiring connects the command center to your new system, ensuring it communicates perfectly for precise temperature control.
These detailed steps reflect our comprehensive approach, which you can learn more about in our Heating Installation Steps We Take guide.
Your Complete Furnace Installation Checklist: From Start to Finish
This critical testing phase separates a professional installation from a rushed job. Our furnace installation checklist includes comprehensive safety and performance checks to ensure your system is ready to keep your family comfortable and safe.
Critical Safety and Performance Checks
Once physical connections are made, our technicians perform a thorough examination. This critical phase can take an hour or more.
Gas leak testing is our first and most critical safety check for gas furnaces. We use sensitive electronic detectors to check every joint and fitting for even the tiniest gas leaks, ensuring your home’s safety.
The combustion analysis measures how cleanly your furnace burns fuel. Using digital analyzers, we check for safe levels of oxygen, carbon dioxide, and especially carbon monoxide (CO) to prevent dangerous situations.
Electrical safety checks are vital. We verify that every wire is secure, the electrical load is correct, and all grounding is in place to prevent fire hazards.
Airflow verification ensures optimal comfort and efficiency. We measure the volume of air your system moves and perform a static pressure test to see how hard it works to push air through your ducts. High static pressure is inefficient and causes unnecessary wear.
These checks align with industry standards like the ACCA Quality Installation Standard, ensuring your installation meets the highest professional benchmarks.
System Startup and Final Testing
Next, we start up the new system to put it through its paces.
For systems with cooling, refrigerant charging is done with precision. We measure superheat and subcooling to ensure the system has the exact amount of refrigerant for optimal performance.
The temperature split test proves the system is working as designed. We measure the air temperature entering and leaving the furnace to confirm it’s transferring heat efficiently. For AC, a 16-22°F temperature difference between return and supply air indicates proper cooling.
Thermostat verification ensures the controls communicate perfectly with the furnace. We test all modes, settings, and programmable features.
System cycling involves running the furnace through multiple on-and-off cycles to check for smooth startups and listen for any unusual sounds. Any issues are addressed immediately.
Finally, we handle the final cleanup. All debris is removed, protective coverings are taken up, and the work area is left tidy.
This level of thoroughness is possible because our team invests in continuous education, as reflected in the fact that our HVAC installers complete 100 hours of training every year.
