"Lockhart Electric has done several projects for me. Everything from replacing switches and fixtures to upgrading my breaker panel. They are always so helpful and knowledgeable. The prices are always fair, and they always give me options to help me make the best decisions depending on my need and my budget. I trust them with my home and I wouldn't call anyone else."

"I was very impressed with Rich throughout the entire process of working with him. He gave us the best price for the same appliances the other companies were going to install. Rich was the only one who actively followed up and answered all of my questions prior to hiring him. When we did hire him, he arrived on schedule and completed the job on schedule as well. I was very impressed with his professionalism. I would recommend Rich to anyone in the market for a new HVAC system. I will hire him again for maintenance and other HVAC needs."

"We woke up to a 63 degree house. Not good in Illinois in early February. Checked the boiler, and the pilot light was out. I could not get it to light again. I contacted an HVAC only company, and they told me, since it was a boiler system, I needed to contact a plumber. Ameriplumb has been recommended to me by Custom Home Updates, so I called. They fit me into their busy schedule the same day (rare these days), fixed the problem (thermocoupler) at a very reasonable price, and they were very pleasant, courteous and efficient. Heat was on that evening (which is good to know with a one year old in the house).

"This is the second time we have used them, and we will use them again. Eric and his guys did an excellent job. They are thorough and professional. Carpets looked great and our dryer vent got a much needed cleaning. These are honest, helpful people who do a great job at a fair price. Highly recommend."
