Straight pricing

What moves the number.

No mystery math. Four things decide what a comfort system costs, and we walk every one with you before the quote lands.

System & efficiencyThe equipment your load calculation calls for, and how efficient you want it to run. Right-sized always beats oversized.
Ductwork & accessThe condition of your existing ducts, and how easily the furnace or air handler can be reached. Tight crawlspaces and attics take longer.
Your existing setupMatching the electrical and refrigerant lines already in place, and hauling the old equipment out clean.
Timing & seasonFlexible scheduling in the off-season costs less. A no-heat or no-cool emergency can be met, priced plainly.

Whatever the mix, it lands as one flat number, in writing, and it does not move.

Good to know

Questions, answered

Getting started
Do you charge for estimates?+
No. Written estimates for installs, repairs, duct work and comfort plans are always free, we visit, measure, talk through the options, and email you a clear, itemized quote with no obligation.
How soon can you start?+
Most estimates go out within a day, and typical projects are scheduled within one to two weeks. For urgent retrofits, before a move, a sale or an event, just tell us the date and we'll do our best to fit you in.
What does “upfront flat pricing” mean?+
Before any work begins, we give you one clear, flat price to approve, prep, materials and labor included. No hourly meter, no surprise add-ons at the end. You always decide before we start.
What should I do before you arrive?+
Nothing heroic. Clear a path to the furnace or air handler, note what the system is doing and when, and keep pets comfortable, we bring shoe covers and leave rooms as we found them.
Do you charge extra for evenings or weekends?+
No. The flat price for a job is the price. Weekdays or Saturday makes no difference, and there is no service call fee, you pay for the fix, not the visit.
Can you give a price over the phone?+
A realistic range, yes. The flat number lands after the assessment, in writing, before any equipment is ordered, that part never varies.
What happens during the free assessment?+
Load calculation, duct check, equipment health readings and a conversation about how you actually live in the house, then a plain-English plan with one flat number per option.
How fast can you get here?+
No-heat and no-cool calls jump the line, usually same-day. Planned work books within the week, with a live arrival text instead of a four-hour window.
Equipment, sizing & efficiency
What brands do you install?+
We are an American Standard partner and a Ruud Pro Partner, and we install major-manufacturer equipment we can still get parts for in fifteen years, matched to your house rather than a quota. Have a preference? We quote it.
How do you size a system?+
A room-by-room Manual-J load calculation, windows, insulation, orientation, the lot. Sizing from square footage alone is how houses end up clammy or short-cycling.
Will a new system lower my bills?+
Usually, and we will show the math honestly, efficiency ratings, your rates, realistic run hours. If payback is thin we say so, sometimes duct sealing is the better first move.
Do heat pumps really work here?+
San Antonio is near-ideal heat pump country, mild winters, real rebates. Cold-climate models heat comfortably well below freezing, with backup heat for the rare arctic week.
Do you handle permits and rebates?+
Both. Permits pulled and inspections met on every install, and we file the utility rebate and tax-credit paperwork with you before we leave.
What filter should I buy, honestly?+
A properly sized media filter beats any gadget, we write your exact size on the cabinet and put it in your file. Members get theirs swapped at every tune-up.
Comfort, ducts & the Care Plan
Why does one room never match the thermostat?+
Ducts, almost always. Leaky, crushed or unbalanced runs starve the far rooms. Sealing and balancing usually fixes it without touching the equipment.
Which temperature is right for my home?+
Tap through the Comfort Studio above, the whole page takes on the mood of each degree. Then set your real thermostat with us during the assessment.
Is the Care Plan worth it?+
For most homes, yes: an annual inspection, free scuff and touch-up visits, priority scheduling, and 15% off future projects typically pay for the membership the first time you use it, and keep every finish looking new.
