You’ve decided it’s time for a new HVAC system. The quote is in. The date is set. But now you’re wondering—what actually happens next?
At H&H Heating and Air Conditioning, we believe you deserve complete transparency. This guide walks you through the full installation process so there are no surprises.
The Consultation: What Happens Before We Quote
Every successful installation starts with a thorough in-home assessment. We evaluate your existing system, ductwork condition, insulation levels, window placement, and how you use each room.
Manual J Load Calculation: Why It Matters
This is the step many contractors skip—and it’s the most important one. A Manual J calculation is the ACCA industry standard for determining exactly how much heating and cooling your home needs. It considers your square footage, ceiling heights, windows, insulation, sun exposure, and Richmond’s specific climate data.
Why does proper sizing matter? About half of all HVAC systems are sized incorrectly. An oversized system short-cycles—running briefly, shutting off, then starting again. This creates humidity problems (your home feels cool but muggy), uneven temperatures, higher energy bills, and premature equipment failure. An undersized system runs constantly but never reaches comfortable temperatures.
We’ll also discuss efficiency ratings (SEER2, AFUE, HSPF2), equipment options, and help you choose what fits your budget and comfort goals. Every H&H consultation is free, no-obligation, and pressure-free—because our technicians don’t work on commission.
Installation Day: What to Expect
Most residential installations take 4-8 hours for a straightforward replacement. Full system installations may take a full day.
Our crew arrives, reviews the job with you, and protects your floors, walls, and furniture with drop cloths and coverings before any work begins. We safely remove your old equipment—including EPA-required refrigerant recovery—then install your new indoor and outdoor units, refrigerant lines, condensate drainage, electrical connections, and thermostat.
What can extend the timeline? Ductwork repairs, electrical upgrades, difficult access locations, or unexpected issues discovered during removal.
Testing, Calibration & Your Walkthrough
Installation isn’t complete just because equipment is in place. We perform pressure testing, verify refrigerant charge, check electrical connections, measure airflow throughout your home, and test all safety controls.
We’ll walk you through operating your new system, explain filter maintenance, and program your thermostat. We also handle warranty registration—most manufacturers extend coverage from 5 to 10 years when equipment is registered within 60 days.
What Affects Installation Cost
System Type: Central AC with gas furnace, heat pump, dual-fuel, or ductless mini-split—each serves different needs and budgets.
Size and Efficiency: Larger homes need larger systems. Higher efficiency ratings (SEER2, AFUE) cost more upfront but save 20-40% on utility bills long-term.
Ductwork Condition: This is often the biggest variable. Leaky ducts can reduce efficiency by up to 30%. We’ll assess your ductwork and only recommend work that’s truly needed.
Installation Complexity: Equipment location, electrical requirements, and home layout all factor into the final price.
Not sure what’s right for your home? We’ll give you honest options—not a sales pitch. Our Price Match Guarantee ensures competitive pricing without sacrificing quality.
How to Prepare for Installation Day
A little preparation goes a long way toward a smooth installation. Start by clearing the areas around your indoor and outdoor units—move any stored items, furniture, or debris so our team has easy access to work. If you have pets, plan to keep them secured in a separate room or with a friend for the day since doors will be open and equipment will be moving through your home.
Keep in mind that your heating or cooling will be off for several hours during installation, so dress accordingly or have fans or space heaters available if needed. We ask that you be available at the start of the job so we can review the work with you, and again at the end for your system walkthrough and any questions you might have about operating your new equipment.
