"Need A/C repair on a heat wave week that struck California. I Called more than 8 companies and everybody is busy, can't come, etc, only Diego and His wife accomodate us in our bad hot summer days! Thank you Diego! HVAC utor service for coming to fix our A/C. Saving up money to change my a/c. I will call you when I have the money ready!"

"Sal from ABC Cooling and Heating came a day after I called the company (I got an appointment with them 5 minutes after sending the email requesting an appointment). He was professional and pleasant. He explained to me how to clean the filters in my furnace and how to install them back in place, thus saving me $200. I appreciated his advice, as I really didn't want to spent that money on him simply just washing the filters, a do-it-yourself job, if the home owner is able to do it. At the end, we were able to replace a bad capacitator and figure out that the compressor worked just fine with this new part. I paid $234 for the capacitator, $59 for the home visit and labor and got 10% off as a member of Angie's list. I am not sure if it was a good price or not for the capacitator (I didn't check prices online), but I was perfectly happy with the job and Sal. I think that $59 was a good price for the labor, considering that you have to pay this fee anyways for the diagnostic/home visit."

"Great. Very professional. i have used them before and would highly recommend them. Rubin, the service representative took pictures of all the parts of the AC and heating systems and e planned where needed repairs or parts replacements may be necessary. Gave the system a good cleanup and completed required maintenance. As to price, I think this is around $100 for a visit in the spring and another one in the fall."

"Legacy plumbing provided us with excellent customer service, professionalism & knowledgeable skill set. When I called Drew, he returned my call right away. He answer all my questions. Drew scheduled the tankless water heater conversion right away that fit our schedule. Legacy plumbing also has great prices !! We have built & remodeled several homes and consider Legacy at the top of our contractors list for plumbing."

"Fantastic! Romeo and Efram were prompt, explained everything, and showed me exactly what they were going to do. My attic was a disaster, the insulation had been ripped to shreds, there were animal feces everywhere, if I remember correctly there was also a dead rat up there somewhere. The ducts were old and ripped and worthless as far as maintaining a consistent temperature in the house. it was absolutely disgusting. They really had to work their butts off to get it all done right. They put up plastic to contain the area so no particulate escaped into the air and contaminate the rest of the house. They showed me the insulation and explained how it was being put in. They explained why they put in disinfectant, and what type of disinfectant they use, that it was all natural and nontoxic. (I even looked online to see how well it worked - reviews were great) They cleaned all debris so thoroughly it didn't look like we had any work done. It was awesome. After a few hours, when it was done they had me go up into the space and, WOW, it looked brand new. I was floored. When we turned on the a/c and the heat it didn't feel like each room was a different temperature zone, everything worked perfectly. My husband and I were thrilled. Honestly, you couldn't find two more professional and lovely gentleman to have work in your home. I have already recommended Attic Masters to four of my neighbors because I have so much faith that the company and their employees will do a professional and thorough job. I love this company and couldn't be happier."

"The technician was very knowledgeable and checked out our heat pump system thoroughly. His findings indicated that it was working normally and that no repairs were needed by explaining that the efficiency of the heat pump drops off significantly as the outside temperature drops below 40F."

"They did a wonderful job cleaning the heating ducts in my house!"
