Frequently Asked Questions - HVAC in Lewisville, TX
These are the questions we hear most from homeowners in Lewisville, Carrollton, and the surrounding North Texas towns, answered plainly and without the sales pitch. If your question isn't here, call (844) 761-3596 and we'll answer it.
Pricing & Cost FAQs
Most HVAC repairs in Lewisville land somewhere between $150 and $800, depending on the part and how deep the diagnosis goes. A capacitor, contactor, or blower motor swap sits at the low end; a failed compressor or a refrigerant leak that needs evacuation and recharge pushes toward the top. What we won't do is quote you a number before we've seen the system. That's why the estimate is free and the price is set per job by the written estimate - you know the total before any work starts. Call (844) 761-3596 for an exact quote.
A full AC and furnace replacement in Lewisville typically runs $6,500 to $14,000, with most homes settling in the $8,000 to $11,000 range. The variables are real: tonnage needed for your square footage and window load, whether the ductwork needs sealing or resizing, and how efficient you want to go. Texas summers are long, and a properly sized 16 SEER2 system will run far less than an oversized builder-grade unit from the late 1990s. Replacement isn't same-day work - it's load-calculated, ordered, and scheduled with a set install date. Call us for a free written estimate.
No. The estimate is free, and we don't charge a service-call or diagnostic fee to tell you what's wrong. We come out, troubleshoot the system, explain what failed and why, and hand you a written price for the repair. If you decide to think it over, that's fine - there's no obligation. Repair visits are priced per job by that written estimate. For a system that won't cool, call (844) 761-3596. We answer 24/7, with fast dispatch from 7am to 7pm, Sunday through Friday.
In Lewisville, a cooling bill that jumps 30-40% between May and August usually points to one of four things: a refrigerant charge that's drifted low, a dirty condenser coil, duct leaks in a hot attic, or a system that's simply undersized or aging out. Houses built in the 1990s and early 2000s around Old Town and the neighborhoods off Valley Parkway often still have original single-pane glass and leaky flex duct, which compounds the load. A proper tune-up and duct inspection will tell you which one is driving your bill. Call for a free estimate.
Yes, a scheduled tune-up is typically $89 to $189 and covers a coil cleaning, refrigerant check, electrical inspection, and a written report of what we actually found. That report is the point: it tells you whether the system is healthy, close to failing, or somewhere in between. Our technicians aren't paid on what they sell, so there's no incentive to talk you into a part you don't need. If something does need attention, you'll get a written price before we touch it. Call (844) 761-3596 to book a tune-up.
Service & Process FAQs
Most repairs are completed in one visit, usually 1 to 3 hours depending on the part. A capacitor, blower motor, or thermostat swap is quick. A refrigerant leak that needs line-set work or a coil replacement takes longer, sometimes a second visit if a part has to be ordered. We'll tell you upfront if we expect to need a return trip so you're not caught off guard. If your system is down, call (844) 761-3596 - we answer 24/7 and dispatch fast from 7am to 7pm, Sunday through Friday.
A live coordinator answers, takes down your address and what the system is doing, and connects you with the local team that will come out. We answer 24/7. A call outside dispatch hours is booked into the next opening, Sunday through Friday, 7am to 7pm. No voicemail, no waiting until the next business day. If it's 9pm and your AC just quit, you'll still get a real person who can get you on the schedule. Call (844) 761-3596.
If the system is under 10 years old and the repair costs less than about a third of a new install, repair is usually the right call. If it's 15+ years old, running R-22 refrigerant, and has had two or more major failures in the past three years, replacement usually makes more financial sense. In Lewisville's climate, an aging system gets pushed hard from May through September, and repair costs tend to climb as it ages. We'll give you both numbers and let you decide. Call for a free written estimate on either path.
Yes, but the scope matters. Small commercial spaces - offices, retail suites, restaurants - are handled through independent local professionals in our network who carry commercial licenses and equipment. For larger rooftop units or multi-zone systems, we'll confirm the right team is available before booking. The process is the same: a free written estimate, a set appointment, and no surprises on the invoice. Call (844) 761-3596 with your building type and we'll get you scheduled.
Three quick things: the thermostat is set to COOL and below room temperature, the air filter isn't clogged, and the outdoor disconnect switch near the condenser is in the ON position. That catches roughly a third of "no cooling" calls. Beyond that, don't open the electrical panel or poke around the compressor - those components carry lethal voltage and require a trained technician. If the system won't cool after those checks, call (844) 761-3596 and we'll get someone out.
Brands & Parts FAQs
We service all major brands, including Daikin, Bryant, Carrier, and American Standard. Parts availability is the real variable - Daikin and Carrier have the widest distribution in North Texas, so common components are usually available same-day. Bryant and American Standard are similarly well-supported. For older or less common brands, we may need to order a part, which adds a day or two. We'll tell you upfront which case you're in. Call (844) 761-3596 with your model number if you have it.
In most cases yes, with a caveat. We'll install equipment you've purchased from a retailer, but the manufacturer warranty is often voided or shortened when the unit isn't installed by a licensed contractor. That's a real risk on a $4,000-plus system. We'll walk you through the warranty implications before we touch it, so you can make an informed call. In most cases, buying through the installing contractor protects you better. Call for a free estimate and we'll lay out both options.
Independent professionals in our network carry common parts - capacitors, contactors, thermostats, filters, igniters - on their vehicles. Less common parts like blower motors, control boards, or compressors are sourced from local supply houses, which means a second visit is sometimes needed. We'll tell you at diagnosis whether the fix is same-day or next-day. There's no surprise charge for the wait. Call (844) 761-3596 for an exact quote on your repair.
Licensing & Insurance FAQs
Yes. Every pro working under our name is required to hold the license and insurance their state requires, and we verify that before any work is booked. In Texas, HVAC work requires a license from the Texas Department of Licensing and Regulation, and technicians handling refrigerant must hold EPA Section 608 certification. We don't send anyone out who can't produce those credentials. If you'd like to see them before the visit, ask - it's a reasonable request. Call (844) 761-3596 with any questions about credentials.
It's covered. Every independent professional in our network is required to carry liability insurance, so if a technician damages drywall, a ceiling, or anything else during the job, that insurance responds. Document the damage with photos, call us the same day, and we'll connect you with the right people to get it resolved. This is one of the reasons we only work with insured pros - it protects you, not just us. Call (844) 761-3596 if you have a concern about a completed job.
For a straight equipment swap, most North Texas cities require a mechanical permit, and a licensed contractor has to pull it. For a full system replacement or ductwork changes, permits are almost always required and an inspection follows. The independent professionals in our network handle permitting as part of the job - we'll tell you upfront what your city requires and factor it into the written estimate. If a contractor tells you permits aren't needed for a full replacement, get a second opinion. Call (844) 761-3596 with questions.
Same-Day Service & Response FAQs
Often yes. We answer 24/7 and dispatch from 7am to 7pm, Sunday through Friday. If you call in the morning, there's a strong chance we can get a technician out the same day, especially for no-cooling calls in the summer. If the schedule is full, we'll give you the next available slot and a clear window. We're closed Saturday, so a Saturday call gets booked into Sunday's opening. Call (844) 761-3596 and we'll tell you exactly what's available.
Call anyway - we're closed Saturday, but the phone line is live. We answer 24/7, and a Saturday call gets booked into the next opening, Sunday from 7am. If the house is dangerously hot, especially with children or elderly family members, get to a cooler space first and call us from there. We'll get you on the Sunday schedule and confirm the arrival window. Call (844) 761-3596.
In most cases within a few hours during dispatch hours, 7am to 7pm, Sunday through Friday. No-cooling in a Lewisville summer isn't just uncomfortable - indoor temperatures can climb into the 90s within hours, which is a genuine health risk for infants, elderly residents, and pets. That's why we prioritize these calls. Call (844) 761-3596, and if you're outside dispatch hours, we'll book you into the next opening. We answer 24/7.
Warranty & Guarantees FAQs
Parts carry the manufacturer's warranty, and labor is covered by a workmanship warranty from the independent professional who performed the job. The exact terms depend on the part and the brand - a Carrier compressor carries a different warranty than a capacitor - and we'll spell it out on your written estimate before any work begins. Keep that paperwork; you'll need it if a claim comes up. If something we repaired fails inside the warranty window, call us and we'll make it right. Call (844) 761-3596 with warranty questions.
Yes. A new system typically carries a manufacturer's parts warranty (often 5 to 10 years depending on the brand and registration) plus a labor warranty from the installing contractor. The catch: most manufacturer warranties require registration within a set window of installation, and skipping that step can cut the coverage significantly. The independent professionals in our network handle the registration paperwork as part of the install. Ask for the warranty terms in writing before you sign the estimate. Call (844) 761-3596.
For a filter change or a thermostat battery, yes. For anything involving refrigerant, the compressor, the control board, or the electrical panel, no. Refrigerant handling requires EPA certification and a recovery machine, and the capacitors and contactors inside a condenser hold a lethal charge even after the power is off. Every year, homeowners get seriously hurt trying to save a service call. The repair itself often costs less than the emergency room visit. Call (844) 761-3596 for a free estimate before you touch anything.
A full system replacement usually takes one to two days, scheduled in advance. It's not same-day work - the system needs a proper load calculation, equipment is ordered for your specific home, and the install date is set before the crew arrives. Ductwork modifications or a line-set replacement can extend it to three days. We'll give you a firm install window when you book. The written fixed price is locked in before we start. Call (844) 761-3596 for a free estimate on a replacement in Lewisville.
