What Houston customers ask before they call.

Yes. Calls placed before 2 PM in our service area generally receive a same-day diagnostic and, in most cases, same-day repair. After 2 PM we schedule a priority next-morning window or dispatch after-hours for emergencies.

Houston, Katy, Cypress, Spring, The Woodlands, Humble, Conroe, Sugar Land, The Heights, Tomball, and surrounding Houston-area communities. If you are unsure, call us with your ZIP code.

We offer after-hours and weekend emergency dispatch for system failures during extreme heat or cold. Emergency rates are disclosed up front before dispatch.

During business hours, most diagnostic calls receive a same-day window. Our office answers calls during business hours; voicemails and form submissions are responded to within one business hour during the week.

Yes. HOA, apartment community, and property management HVAC is a core specialty. Recurring maintenance, make-ready turnover, and common-area systems with a single point of contact and consolidated invoicing.

We diagnose first, then present a flat-rate quote covering parts and labor. The price you approve is the price you pay. No hourly creep, no surprise items at the end of the job.

Most common Houston AC repairs fall between $150 and $600 (capacitors, contactors, drain lines). Mid-tier repairs (refrigerant leaks, electrical, blower motor) typically run $600 to $1,500. Major repairs (compressor, evaporator coil replacement) range $1,500 to $2,800 or more. See our repair cost guide for detail.

Yes, there is a flat diagnostic fee that covers the technician visit and a full system check. The diagnostic fee is disclosed when you book and is credited toward the repair if you approve the work the same day.

Yes, financing options are available on full system installations through third-party lenders. We will quote a system without financing and let you decide whether to apply.

Credit and debit cards, ACH transfer, and check. Invoices for commercial and property management customers are net 15 by default; net 30 available on volume contracts.

We do not apply percentage surcharges to labor in peak summer. Our flat-rate pricing remains the same year-round. After-hours emergency dispatch is the only time a different rate applies, and it is disclosed before we send a technician.

We confirm the appointment window in advance, the technician arrives in a marked vehicle, performs a full diagnostic, presents findings with photos when relevant, quotes a flat-rate repair, and only begins work after you approve.

No. Our technicians are paid to fix problems, not to hit sales quotas. If a repair is the right answer, we recommend repair. If replacement is the right answer based on age, repair cost, and your usage, we explain why and present options.

Yes. Our workmanship is warrantied for 90 days on standard repairs and 1 year on installations. Equipment carries the manufacturer warranty separately, which we register on your behalf at installation.

Houston AC systems run 2,200+ hours per year. Preventive tune-ups catch failing capacitors, low refrigerant, drain line clogs, and dirty coils before they trigger a 100-degree emergency. Plan members pay less for repairs and skip the wait during peak season.

Two preventive visits per year (pre-summer and pre-winter), priority scheduling, discounted repair rates, no after-hours dispatch fees, and a maintenance log we keep for property managers and homeowners selling their property.

Yes. Plans are month-to-month or annual. Annual plans can be canceled with a prorated refund of unused months.

We coordinate with your property manager or maintenance supervisor on the turnover schedule. Filter changes, drain line treatment, coil inspection, and refrigerant verification are batched across units when possible. Findings are documented per unit, invoiced consolidated.
