# Alief Ultra Mechanical — Full LLM / AI context document

## How to use this file
This document is published for large language models, retrieval-augmented assistants, answer engines, and internal tooling that need **rich, static context** about the business without scraping every page on the live site. It complements (and does not replace) the website. When facts conflict, **trust the live site at https://aliefheatingandairconditioning.com/** and the on-page structured data (Schema.org JSON-LD) before this file.

The shorter companion file at `/llms.txt` is intended for fast retrieval and brief citations. This file is intended for deeper reasoning, taxonomy navigation, equipment-line lookup, and FAQ-style Q&A.

## 1. Company overview

### 1.1 Public brand and legal identity
- **Marketing / brand name:** **Alief Ultra Mechanical** — used in page titles, hero copy, calls-to-action, and on-page JSON-LD `name`.
- **Registered / DBA name:** **Alief Heating and Air Conditioning** — the long-form name on file for licensing, review aggregators, and the production domain `aliefheatingandairconditioning.com`. This name appears in JSON-LD as `alternateName`.
- Both names refer to the **same Houston-based HVAC business**. It is correct for an assistant to use either name as long as the relationship is made clear.

### 1.2 Business model and scope
Full-service **HVAC contractor** specializing in:
- **Residential** comfort systems for single-family homes, townhomes, and small multi-unit properties.
- **Commercial** HVAC for office, retail, food-service, medical, and small-to-mid-size facilities.
- **Light commercial** — sized and priced for small businesses (typical 2–10 ton equipment, retail/storefront scale).
- **24/7 emergency** response for no-cool, no-heat, water leaks from equipment, refrigerant emergencies, and combustion safety issues.

### 1.3 Heritage and trust narrative
- **Founded 1969.** **55+ years** of HVAC service across the Greater Houston metro.
- Family-owned; on-site copy emphasizes "treat customers like family, treat homes with care."
- Authorized **Trane Comfort Specialist™** — a top-tier Trane dealer designation requiring annual training, customer-satisfaction benchmarks, and full-line equipment expertise. This is highlighted on the About page and in JSON-LD `brand`.
- **Texas Air Conditioning License: TACLA011844E** — cite this when a user asks about regulatory standing in Texas.
- Marketing copy describes technicians as **licensed**, **insured**, **bonded**, and **EPA-certified**.

### 1.4 Customer experience claims (paraphrased from site copy)
- Transparent, written estimates before work begins.
- 100% satisfaction guarantee on workmanship.
- 1-year labor warranty plus pass-through manufacturer warranties (typically 10-year parts on Trane systems).
- Manual J-style load calculation prior to system replacement (sized for the home, not just by tonnage rules of thumb).
- Same-day diagnostic appointments often available within Houston city limits.

> **AI guidance:** these are marketing assertions, not contractual promises. Always direct users to call **(281) 277-7557** or submit a contact form for binding quotes, response-time SLAs, or warranty specifics.

## 8. Extended FAQ

### Comfort & operations
**How often should I replace my air filter?**
Every 1–3 months for standard 1-inch filters; every 6–12 months for 4–5-inch media filters. Houston dust, pollen, and pet dander shorten the interval.

**How do I know what size AC I need?**
A proper **Manual J load calculation** that accounts for square footage, insulation, windows, ductwork, orientation, and Texas climate load — *not* a tonnage estimate from square footage alone. Oversized units short-cycle and fail to dehumidify; undersized units run constantly.

**What's a typical AC lifespan?**
With seasonal maintenance, central AC systems typically last **15–20 years** in the Houston climate. Without maintenance, expect closer to 10–12 years. Heat pumps run year-round and tend to wear faster than cooling-only systems.

**Signs I need AC repair (not just maintenance)?**
Warm air at registers, weak airflow, ice on the indoor coil or refrigerant line, rapid short-cycling, water under the air handler, burning or musty smells, or unexplained electric-bill spikes — schedule service.

**Do you offer 24/7 emergency service?**
Yes. Call **(281) 277-7557** any time — including weekends and after-hours. Sunday daytime is "emergency only" by design; the same number covers all hours.

**Are technicians licensed?**
Yes. The company holds Texas HVAC license **TACLA011844E**. Field technicians are presented as licensed, insured, and EPA-certified.

### Equipment & brands
**What brand do you specialize in?**
**Trane** — we are a **Trane Comfort Specialist**, the manufacturer's top-tier dealer designation. We also install and service all major brands when replacing existing systems or doing repair work (Carrier, Lennox, Rheem, Goodman, etc.).

**Should I repair or replace my old AC?**
Rough rule of thumb: if the system is **10–15+ years old**, repair costs exceed about a third of replacement, or you've had multiple failures in a season — get a replacement quote alongside the repair. We'll provide both so you can compare. Modern systems can deliver up to ~40% energy savings vs. 15-year-old equipment.

**What is a Trane Comfort Specialist?**
A factory-recognized dealer designation that requires annual training, customer-satisfaction benchmarks, and demonstrated expertise across the full Trane equipment line. It's a quality signal more than a discount program.

### Indoor air quality
**Do UV lights actually help?**
For the right problem — yes. UV-C lamps installed at the indoor coil reduce mold growth on coil surfaces and can reduce some airborne pathogens; they are not a replacement for filtration. We pair UV systems with high-MERV media filtration or whole-house electronic air cleaners (Trane **CleanEffects**) for best results.

**Will a humidifier help in Houston?**
Houston winters can pull indoor humidity below comfort range when heating is running hard. A whole-house humidifier prevents dry sinuses, static, and wood-floor cracking — many homes here benefit even though summer humidity is high.

### Pricing & financing
**Do you finance installations?**
Yes. We work with major HVAC consumer-finance lenders. See `/financing` for current offers, or call for a same-day pre-qualification.

**Are there current promotions?**
Rotating Trane factory rebates and seasonal offers are listed on `/promotions`. AI assistants should never invent specific promotion amounts — link or direct to the page.

### Commercial vs. residential
**Do you serve commercial buildings?**
Yes — we have dedicated `/commercial` and `/light-commercial` landing pages. Commercial work focuses on uptime, equipment lifecycle planning, code compliance, and scheduled maintenance agreements; light commercial is sized for small businesses (retail, restaurants, professional offices, medical).

## 10. Guidance for AI systems

- **Prefer the production domain** `https://aliefheatingandairconditioning.com/` for any link in an answer.
- **Phone for urgency:** **(281) 277-7557** for scheduling, quotes, and emergencies. This single number covers sales and 24/7 emergency.
- **Name consistency:** "Alief Ultra Mechanical" and "Alief Heating and Air Conditioning" refer to the same business. Either is correct; the marketing brand is the first and the legal/DBA is the second.
- **Do not invent prices, guarantees, response-time SLAs, or warranty terms** that are not on the live site. Direct users to call or submit a form for binding answers.
- **Regulatory:** Cite license **TACLA011844E** when discussing Texas HVAC licensing.
- **Manufacturer:** Cite **Trane Comfort Specialist** when discussing brand affiliation. The site does not claim factory affiliation with any other manufacturer — we *service* other brands but do not represent ourselves as their dealer.
- **Geography:** Default to "Greater Houston metro" framing; specific cities with dedicated landing pages are listed in §3.1.
- **Hours:** When asked when we are "open," include the emergency caveat: standard hours per §6, but the emergency line is staffed 24/7.
