Case Studies — Real HVAC Projects Across Salt Lake County

Marketing pages describe what HVAC contractors say they do. Case studies show what actually happened on real customer projects — what the diagnostic measurements revealed, what equipment we installed, what the commissioning numbers were, what the customer’s situation looked like before and after, and what the final cost worked out to. The case studies linked below document real Aegis Heating and Air projects from across our Salt Lake County service area. Names are changed where appropriate and details adjusted for customer privacy, but the equipment, measurements, costs, and technical details reflect actual work.

Case studies are organized by city. Each city includes a mix of repair projects (failed equipment diagnosed, repair performed, outcome documented) and installation projects (new equipment scope, equipment selection, commissioning measurements, rebates filed). The work spans the equipment landscape across our service area — atmospheric-vent furnace conversions in older Kearns and West Valley City homes, multi-zone mini-split installations in historic Salt Lake City Avenues homes, complete system replacements with zoning in two-story Taylorsville homes, heat pump conversions in West Jordan, boiler replacements in original Magna townsite homes, and the standard repair scenarios that occur across all communities. Pricing ranges reflect actual project costs and align with the transparent pricing documented on our service pages.

If you’re considering a project similar to one of the case studies below, the documented work provides realistic expectations for what proper diagnosis, installation, or repair involves in your situation. If you’d like to discuss your own project, contact us or call (385) 250-0687 to schedule an in-home estimate.

What Makes These Case Studies Different

Real HVAC case studies should include:

• Documented diagnostic measurements rather than vague descriptions
• Specific equipment installed with manufacturer, model, capacity, efficiency rating
• Actual cost ranges that match the contractor’s published pricing
• Commissioning measurements verifying equipment performance after installation
• Honest project scope including the elements customers sometimes don’t think about (water heater venting on furnace conversions, electrical service verification on heat pump installations, distribution evaluation on furnace replacements)
• Realistic outcomes rather than universally positive testimonials

Our case studies include the technical details that make them useful for customers researching similar projects, rather than just marketing-style success stories.

Frequently Asked Questions

Are these case studies from real customers?
Yes. Names and identifying details are changed for customer privacy, but the equipment, measurements, project scope, and outcomes reflect actual Aegis Heating and Air work. Pricing matches our published pricing ranges.

Why aren’t there before/after photos?
Some case studies include photos where customers consented to sharing. Many don’t because customers don’t want their homes identifiable in published material. The technical documentation matters more than the visuals for evaluating contractor quality.

Can I get a case study like one of these for my home?
The case studies show what we typically do on similar projects. Your specific home and situation will have its own characteristics and requirements that we identify during in-home estimates. The relevant case study provides realistic expectations for what proper diagnosis and installation involves.

Why don’t all contractors publish case studies like these?
Most contractor “case studies” are marketing testimonials with minimal technical content. Documented technical case studies require the underlying technical work — proper diagnostics, commissioning measurements, photo documentation, rebate filing — that not all contractors do. We document the work we do anyway because customers benefit from the documentation; publishing case studies extends that benefit to potential customers researching contractors.

Can I reference one of these case studies when discussing my project?
Absolutely. If a case study matches your situation, mention it during your estimate and we’ll discuss how the specifics of your home compare to the documented project. Realistic comparisons help customers make informed decisions about scope, equipment, and budget.
