About Allen HVAC Services
Founded in Royse City in 2004, Allen HVAC Services holds license TACLA023580E and maintains a perfect 5.0-star rating across 14 client reviews. This family-operated business serves residential and light commercial clients across Dallas, Rockwall, Southern Collin, Hunt, and Kaufman counties, with a Master Technician present on every service call and most systems restored within 24 hours.
What distinguishes Allen HVAC Services is their parts-finding tenacity. The team tracks down rare components others claim do not exist or carry excessive lead times, and they specialize in repairing systems deemed irreparable by competitors. They service all makes and models including Lennox units, offer same-day repairs without exaggerated wait times, and provide upfront not-to-exceed pricing with no scare tactics about refrigerant phaseouts just to encourage upgrades.
Reviewers consistently highlight specific technicians and scenarios. Keith Allen recently resolved a compressor stall and atypical technical issues on a Lennox system that another contractor could not fix. For one homeowner facing time-sensitive circumstances, the team accommodated a tight schedule without overcharging, getting the system operational again.
What Customers Say
Fourteen reviewers award perfect 5-star ratings, with nine specifically praising honest pricing and refusal to upsell unnecessary replacements. Customers name Keith and his son as knowledgeable technicians who prioritize repairs before recommending replacement.
