"It is rare these days to find a great company with good values. This is one of those instances; I cannot say enough, good things about the professionalism of the employees at the office and those that showed up on site to install wall insulation. They showed up at the beginning of the two hour window, which was fantastic and explained everything with upfront pricing. We even asked for additional insulation and they were able to accommodate. Our home walls are now insulated and we even noticed a difference right away. From the time of arrival to completion they were nothing but exemplary. Thanks again for running an honest and professional team! Highly recommend to anyone out there looking to insulate your home!!! Notability, they were well below other companies on pricing too!!!"

"Turner Air Conditioning scheduled the visit at a time convenient for me, showed up at the time promised and did an excellent job. For $49, Brian spent 1 ½ hours servicing my furnace which had a dangerous pre-ignition issue. He determined the issue immediately, made the repairs necessary, made other needed adjustments and kept me informed as to what he was doing and why. He was friendly and knowledgeable. We need to replace our 40 year old HVAC system and I will call Turner when we are ready to do this. <br />"

"When they came out to give an estimate, they did a thorough evaluation and not only gave options and a recommendation, but explained in detail why they were recommending what they were. They also gave a lower quote than other companies that we contacted. The installation process went smoothly. They were on-time, prepared with everything they needed, and completed the job quickly and cleanly."

"The Progressive team was great throughout the process. Sam, the salesman, was punctual and professional, and was happy to revamp my estimate a few different times based on some changes we were considering. The installation team was very clean and I am very happy with the look of the new windows. They went above and beyond with their trim work and they did a great job matching the stucco on the exterior of the house (the inspector even commented on the quality). There was a scratch on one of the panes that we noticed right after installation, and they helped us get it replaced right away. I have also had to call back for minor questions (getting an updated invoice for tax purposes, etc) and they have always gotten back to me same-day. I highly recommend working with this company, especially since their prices were so reasonable compared to the other companies I got estimates from."

"I’m extremely satisfied with their service! We hired them to do the clearing and installing for the new insulation in my attic a few months ago. It was very easy to set up an appointment over the phone. Adam, the owner, was very helpful every step of the way. They worked super fast to help install the insulation and disposed of the previous one. Great job and thank you guys!"

"Jack Mair of the company was excellent. Everything was upfront, honest, done on the proper timeline (especially as Jack advised, we order the materials on time with the subs his company recommends) and the work product was excellent. We have several more projects to our 50 year old home which need done. I will ONLY hire Jack, his company AHI, and subs he recommended. Cost wise, in todays society, would be considered a bit more than fly by night construction companies. My mantra is don’t be cheap with what you eat, how you sleep (bed and mattress) or what you put on your feet ( cheap shoes are NO good)…my new mantra is “I’ve got a better chance of ‘fixing’ the World Series” than anything in my home. so when it comes to home projects I shall hire Jack and AHI because they might actually be able to ‘fix’ the World Series."

"My 1950's house had repetitive rat infestations for years, it got to the point where all the insulation was covered with rat droppings and urine smell leaked into my home. I hired Titan for the pest control job and, on top of getting rid of the rats, they also removed the old insulation, cleaned the entire attic, rat proofed it and installed new insulation. Their crew performed extremely well and their office assisted me in applying for the LADWP insulation rebate, I couldn't be happier."
