The company’s description in Thumbtack and on its website indicated that Home Upgrade Specialist, HUS, is more than simply a heating and air conditioning company. Our December 17 interview with the co-owner, reinforced that impression. First, we want to acknowledge that we are very pleased that HUS made good on its claim that installation of our central heating system would be completed before our house guests arrived on Christmas Day. The biggest problem is that there was very little consultation and poor communication. HUS never came to inspect the job or supervise the installers. After the system was installed the installers could not answer my questions about the use of the system, and they did not respond when asked for information that we would need for emergencies, and for submitting the warranty. The system blew out the electricity within two hours of using it. We looked for the circuit breaker, but there was none installed. We asked HUS to come to inspect and assess the situation. His installers came two days later, fixed the problem, and installed a circuit breaker. Two weeks have passed, the system works fine, however, one issue remains unresolved. HUS gave us a contract indicating the products and services rendered, and the total cost. When the installers came they told HUS that the outside entry door was too small for them to get the furnace into the attic and they would have to cut an access door in our hallway ceiling. HUS then told us that would add to the cost of the project. We agreed and asked to an up-dated contract. We never received the updated contract reflecting the additional cost for the access door to the ceiling. All we got was an email receipt indicating the total amount we paid along with the co-owner’s hand written notes reflecting the changes. We feel it is reasonable to have an accurate itemized invoice as well as a receipt. The system is working fine and that’s the bottom line. However, we would not recommend HUS to anyone because we value good communication, strong follow-up, and a caring professional relationship.

Fantastic company. Simon is polite, communicative, and friendly. They did a great job installing a new central air system for me in my condo and gave me the most competitive price I've found. I'm very happy with this company - it's extremely difficult to find honest and reputable contractors nowadays, but HUS is definitely one you should add to your contacts.

Great experience working with HUS. They were able to accommodate challenges around installing AC without any delay. The results have been top notch and the care and pride they take in their work shows.

Awesome service from Home Upgrade Specialist! Our central air unit stopped working during the weekend and within a couple hours of contacting them through Thumbtack I received a response and an appointment was set up within a day! A technician came to assess the needed repairs, He couldn't do the repairs right then because of parts that were needed but he came back at the same day and quickly repaired our unit and also ran a maintenance cleaning. I would 100% contact them again for any other issue.

Excellent service. very professional. I have two split system units that needed service and one had a freon leak.they came and serviced both machines, refilled the freon, fixed the leaks, changed the filters and installed two new Nest thermostats and all of this was FREE. Yes not one red cent. They did this all under an Ladwp program and there was no hidden charges or anything. Extremely pleased with this company
