John Moore Services is one of Houston's largest multi-trade home services companies, operating from 10005 West Sam Houston Pkwy N with over 19,000 Google reviews at a 4.7-star rating. The company runs 24/7 (Monday through Saturday; Sunday 10 AM to 7 PM) and covers HVAC, plumbing, electrical, whole-house generators, pest control, lawn, and bathroom remodeling under a single brand. A VIP Membership program is available with maintenance benefits and service discounts.

Current HVAC promotions include a $49 30-point heating inspection with a no-breakdown guarantee — if the heating system fails within one year of the maintenance, the tune-up cost applies toward any repairs. Generator installations include $1,000 off whole-house Generac or Kohler standby units. Plumbing specials include a $49 kitchen or mainline unclogging with a 60-day warranty.

Technician-level reviews are consistently positive: David Lawrence is praised for efficient shower valve replacement with a friendly demeanor; Brad Skotak is credited with clear estimates and three-option presentations without rushing decisions; Felipe (electrical) resolved an issue same day; Kahlil showed initiative on a permit follow-up case.

Two substantive 1-star reviews describe systemic administrative failures: one involving a contractor referral that cut a ceiling without repairing it, leading to a $1,900 bill and an open hole; another involving a four-month permit delay for a generator gas line with no resolution despite six escalation contacts. These reviews reflect a gap between field technician quality and back-office follow-through that prospective customers should factor into decisions on larger or multi-phase projects.
