Straight answers, no runaround.

Yes. Mackey Services holds Texas HVAC license #TACLA 112769C and electrical license #TECL 558211, and we're fully insured. We're also a BBB-accredited business with an A+ rating, and our technicians are NATE-certified.

We've been serving Texas families and businesses since 1992 — more than 30 years of local, family-owned service, backed by a 4.9-star rating from over 1,000 Houston-area reviews.

We're open Monday through Friday from 7 AM to 8 PM and Saturday from 8 AM to 5 PM (closed Sunday). Evening slots make it easy to book service without missing work.

Three, under one roof: HVAC (AC, heating, heat pumps, mini-splits, indoor air quality), electrical (panels, rewiring, EV chargers, surge protection), and generators (whole-home standby installation and service). One call handles it all.

We're the Home of the $49 Tune-Up — a licensed technician inspects, cleans, and optimizes your system so it runs efficiently through the long Gulf Coast cooling season. It's the cheapest insurance you can buy against a mid-August breakdown.

At least once a year — ideally each spring before the heat arrives. Gulf Coast systems run far more hours than the national average, and humidity is hard on coils and drain lines. Our Happy Home Maintenance Plan ($16.50/mo) handles the schedule for you and adds 20% off repairs.

A good rule of thumb: if the repair costs more than a third of a new system's price and your unit is 10+ years old, replacement usually wins on comfort and energy costs. We give you an honest assessment either way, and Happy Home members earn up to $1,250 in replacement credits.

Yes — we install and service ductless mini-splits (great for garages, additions, and casitas) and high-efficiency heat pumps that both cool and heat, a strong fit for our mild Texas winters. We carry Lennox and American Standard equipment.

Absolutely. We install whole-house air purification, whole-house dehumidification (a Gulf Coast essential), UV lights, and smart thermostats — all sized to your system and home.

Yes — Mackey holds Texas electrical license #TECL 558211. Our electricians handle panel upgrades, house rewiring, EV charging station installation, surge protection, lighting, and luxury home electrical projects.

Hurricane season and grid strain make outages a matter of when, not if. A whole-home standby generator starts automatically within seconds of an outage and keeps your AC, refrigerator, and medical equipment running. We install and service Kohler and Generac systems.

Standby generators need annual maintenance and periodic exercise cycles. We offer annual generator maintenance and priority storm-season service to keep your standby unit ready when the grid goes down.

Yes. We install Level 2 home EV chargers, evaluate whether your panel can support the load, and handle any panel upgrade needed to charge safely and quickly.

The Happy Home Maintenance Plan — $16.50/mo (or $198/yr) for the first HVAC system, plus $8.15/mo per additional system. It includes two seasonal visits, $0 service calls, 20% off service and repairs, 20% off the online filter shop, priority scheduling, two annual drain-line cleanings, and up to $1,250 in replacement credits. We also provide annual generator maintenance as a service.
