Problems we help with

Help your home hold onto its comfort.

Whether you need new insulation or replacement of existing material, Klein can assess your home and explain the available options. Call us if any of these sound familiar:

  • Some rooms stay warmer or cooler than the rest of the house
  • Insulation you can see is thin, missing, flattened or damaged
  • You’re renovating, finishing a garage or opening up a ceiling
  • You’re concerned about how much energy the house uses

These symptoms can have more than one cause, so we inspect before we recommend anything.

Insulation is one part of the picture. If air isn’t reaching a room, or your system struggles to keep up, ask about an HVAC and ductwork review.

I needed a whole new system! I received assessments and estimates from four other companies, but I chose Klein Heating and Cooling and I’m very glad I did. My hat goes off to owner Tomer and his team of experts. He walked me flawlessly through the entire process from estimate to complete install and I could not be more pleased.

James W. Google review · March 2024

I needed a second opinion after noticing our AC wasn’t cooling down. The original quote was close to the cost of a new system. Tomer walked me through all the possibilities, including total replacement. His knowledge and integrity are unmatched! He was able to recharge my AC to extend its life, saving me thousands of dollars off the original quote.

Meghanne B. Google review · February 2024

We decided to replace our 14 year old condo split system before the heat really gets chugging here in Scottsdale. Tomer took a look at the unit top (4 story roof) to bottom, tested every function and said we could get another season or 2 out of it if we needed to. The estimate was clear and concise. From our agreement to installation was only 3 days. His crew was timely, courteous, efficient and FAST.

Dale R. Google review · March 2026

Extremely quick response time (so important for Arizona!) and they really took their time to analyze every aspect of our A/C to make sure we knew not only what needed to be done now, but also what needed to be done in the future. I expected a pretty hefty bill for such a white glove service, but was so surprised by how competitive the pricing was.

Miles M. Google review · January 2024

I had a new AC/Heating system installed. Because the airflow on one side of the house was a little sluggish, I had them check the situation out, and they determined a new return and larger ductwork would be more beneficial. The guys came out and made the changes. They are excellent to work with, honest, and keep their customers informed.

Janice B. Google review · March 2026

I called Klein Heating and Cooling when I heard a sound coming from my AC unit that just didn’t sound right. They came and resolved the issue within minutes. Charged me an honest fee, no up-selling at all. I would 100% recommend them and will use them in the future.
