Upgrading to a New HVAC System Might Be Easier Than You Think. 
When the summer heat becomes relentless, there’s one thing every homeowner in the Lehigh Valley wants: consistent, reliable indoor comfort. At Jack Lehr Heating, Cooling & Electric, we don’t just promise to keep your home cool – we back it up with our exclusive 72 Degree Guarantee.
This unique commitment sets us apart from the competition and gives you confidence that your new air conditioning system will deliver exactly what you need when temperatures soar. Here’s what the 72 Degree Guarantee is all about, why it matters, and how it reflects our dedication to quality, precision, and your complete comfort.
What Is the 72 Degree Guarantee?
Jack Lehr’s 72 Degree Guarantee is our promise to homeowners that, when we install your new air conditioning system, we guarantee it will maintain a comfortable indoor temperature of 72°F, even during the hottest summer days.
This guarantee isn’t just a marketing slogan – it’s a reflection of the expert-level service, precise system sizing, and superior installation standards we bring to every project. Simply put, if your system can’t keep your home at 72°F when it’s designed to, we’ll come back and make it right. That’s peace of mind you can count on.
Why Does This Guarantee Matter?
Too often, homeowners have an AC system installed only to discover that it doesn’t keep their entire home cool – especially during extreme heat. Rooms may feel stuffy, upstairs areas may never reach the target temperature, and the system might run nonstop trying to catch up.
These issues are typically caused by poor system design, incorrect sizing, or subpar installation. At Jack Lehr, we eliminate those problems from the start. Our 72 Degree Guarantee ensures that:
- Your system is properly sized for your home, accounting for square footage, insulation, windows, and layout.
- Installation is handled by trained, certified professionals who follow best practices and manufacturer specifications.
- Airflow is balanced and ductwork is evaluated, so cooled air reaches every corner of your home efficiently.
- You receive long-term value, knowing your investment is backed by a company that stands behind its work.
The Difference Is in the Details
The 72 Degree Guarantee is just one example of how Jack Lehr is different from the average HVAC contractor. Many companies focus on quick installs and volume, but we focus on getting it right the first time. Our goal isn’t just to sell you a new system – it’s to ensure that system keeps you and your family perfectly comfortable for years to come. We’ve built our reputation on:
- Unmatched workmanship guarantees
- Upfront pricing with no surprises
- Thorough in-home assessments and load calculations
- Post-installation follow-up and ongoing service options
