I have done business with Lorenz for years, and they are one of the best in town!
Very prompt and to the point. Brian was able to fix two separate issues with my furnace in a timely manner. Highly recommend Brian and this company. Thank you!
Tech got to my house less than two hours after I called for repairs, showed me the problematic part, and what it should look like with the new part. Very friendly service.
Extremely quick service! I appreciated how much they kept us in the loop and helped educate us during the repair.
Very reliable, knowledgeable, and affordable. Mike and his guys have never failed in surprising me with their abilities.
You guys always show up ASAP. I feel so secure as a single female with you a call away.
Fast service and showed up on time. Very friendly. Highly recommend Lorenz. Will definitely use them for future needs.
The price was very reasonable, and they finished the job up before noon. Great service.
I scheduled Lorenz to come help me, and they showed up the next day and replaced my mistake quickly!

factors to consider
Should You Repair or Replace Your HVAC System?
There are many factors to consider when making this decision: age of the system, cost, type of repair, as well as what repairs have already been done. One industry rule of thumb that you could use: multiply the cost of the repair by the age of your system in years. If that number exceeds $5,000, replacement is usually the smarter financial decision. For example, a $300 repair on a 10-year-old system lands at $3,000 — likely worth fixing. That same $300 repair on a 20-year-old system hits $6,000 — and replacement starts to make more sense.
Our goal is to help you make the right decision for your specific situation. Not sure where your system stands? Call us and we’ll help you work through it.

Our Client Questions
“While other home repair companies fade away, we’re still here taking care of generations of customers just like you.”
Most residential HVAC replacements are completed in a single day. The exact timeline depends on the scope of work — a straight swap of existing equipment is typically faster than a full system overhaul. Your Lorenz technician will give you a realistic timeframe during your estimate.
In many cases, replacing just the furnace or just the air conditioner makes sense. However, if both units are aging and one has already failed, replacing them together often provides better efficiency and avoids a second installation bill within a short window. We’ll assess your system honestly and help you decide what makes the most sense for your situation and budget.
Yes. All installations come with manufacturer warranties on equipment, and our work is backed by Lorenz’s commitment to quality. Specific warranty details vary by brand and model — your technician will walk you through what’s covered before any work begins.
Absolutely. We offer excellent financing options through Wells Fargo and Wisetack, with approved credit. You can prequalify online at any time. Visit our financing page for details.
We are a certified Trane Comfort Specialist and a Mitsubishi Electric Diamond Contractor Elite, meaning we’re trained and authorized to install and service those brands at the highest level. We’ll recommend equipment based on your home’s needs, budget, and efficiency goals.
Yes. We serve Springfield, Nixa, Ozark, Rogersville, Republic, Willard, Branson, and many surrounding communities throughout Southwest Missouri. Give us a call to confirm service in your area.
A New HVAC System Is an Investment, Not Just an Expense
Heating and cooling technology has improved dramatically over the past 15 years. Modern high-efficiency systems use considerably less energy than older units running at the end of their lifespan — which means lower monthly utility bills that help offset the cost of replacement over time. When you factor in great financing opportunities and the savings on energy and repairs, many homeowners find the math makes more sense than they expected. We’re happy to help you crunch the numbers.
Flexible Financing for HVAC Replacement
A new HVAC system is a significant investment, and we want it to be an accessible one. Lorenz offers great financing options through two trusted providers: Wells Fargo and Wisetack — both with approved credit. You can prequalify directly on our website before you even schedule an appointment.
Financing is provided with approved credit by Wells Fargo Bank, N.A. or Wisetack. Terms and conditions apply. Ask for details.
