Claim This BusinessJ & K A/C & Heating operates from Waller, Texas with a 4.8-star rating compiled across 16 customer reviews. The company maintains 24-hour availability every day of the week, a critical feature for residents in this region where summer temperatures routinely pushing past 95 degrees make HVAC failures genuine emergencies. Court, a verified customer, noted the company saved him $6,500 by correctly identifying a minor electrical issue rather than endorsing a full condenser and evaporator coil replacement that another contractor had recommended. The business employs at least three named technicians who handle service calls directly: Curtis, Jacob, and John.
What distinguishes J & K from competitors is an unwavering commitment to diagnostic honesty over sales pressure. Multiple reviewers specifically contrast their experience with other HVAC companies who pushed unnecessary upgrades. Mark Roby praised Jacob for never attempting to sell services customers do not need. Bethany Paterno reported feeling no push toward expensive or unnecessary work, with pricing she described as fair. The company handles both residential heating and cooling systems, performing capacitor replacements, motherboard repairs, and preventive maintenance. Annual checkups run approximately $75-$100 depending on system age and accessibility, according to customer reports.
Customers consistently highlight specific technicians and the scenarios they resolved. Daniel Lynds has used J & K for three years across four service calls including capacitor and motherboard replacements, noting technician John will not leave until the issue is confirmed fixed. Court recounted Curtis arriving to diagnose what another company flagged as a major failure, then simply replacing a breaker at minimal cost. Saad Mufti specifically requests Jacob for AC and heating issues, citing professionalism, punctuality, and thorough information sharing. The pattern across reviews shows homeowners receiving clear explanations and solutions rather than costly replacements.
Every reviewer assigned a 5-star rating, with 16 total reviews establishing this aggregate. Three technicians are named across reviews, Curtis, Jacob, and John, each connected to specific repair scenarios: breaker replacement, capacitor issues, and motherboard fixes. Customers repeatedly emphasize diagnostic honesty, with Court explicitly contrasting his $6,500 savings against another contractor's quote.
