"I needed a whole house cleaning from the vents to the floors in the new home I bought. No. 1 provided all the services in one and they seemed reasonably priced. Vincent came on time and we went through all the things I wanted done in detail. He quoted me a price and he got to work. Many hours later, the house is amazingly clean and the dryer and HVAC unit is more efficient. The stains came out of the carpet and the tile was returned to original. The dust in the duct was also removed. In regards to the tile floor, I thought the grout was black, but after the cleaning it turned out that the original color was gray. Amazing! We also looked in the dryer vent and realized it had never been cleaned. I can't believe how much stuff came out of a short vent hose. I'm really glad I had it done. As to the professional who came to the house, Vincent was outstanding. He explained everything clearly, was very professional and did the work to the best of his abilities paying attention to detail. I couldn't have asked for more. I would definitely recommend No. 1 and Vincent to others who need the service."

"I have used Speer Air for several years for HVAC preventive maintenance at my home. We recently expanded and they installed a package unit to take care of the expansion space. The work was good and they have been back for adjustments as necessary."

"Miguel and his MDL electric team are very reliable and performed all services when promised, on time, and all work was done correctly. I had a small issue with with a scratch in the ceiling after a new HVAC cover was installed and Miguel had one of his workers respond quickly and correct the issue. MDL also offered a very competitive price and made me feel comfortable from the beginning. MDL replaced a really old electric panel and removed really old HVAC and installed all new HVAC. Would hire MDL again."
