I needed a new HVAC system in a rental property and my friend referred me to McMaster. I got 3 quotes and Ron's (McMaster) was the most competitive for the exact same equipment. The price was obviously an important factor, but the responsive communication from the office (Ron, Josie & Alexis) made working with them super easy. Installation went off with out a hitch - the crew kept everything clean and explained how to use the system before they left. Im definitely happy with McMaster and know who Im going to call when my HVAC needs replacement.
Within an hour of requesting an estimate to replace my aging A/C, Ron, the owner arrived at my home. He assessed the situation and within a few hours, he emailed me a very reasonable quote. I agreed, and the unit was installed later that week, by Al and Dillon, Couteous, knowledgeable and efficient. A very positive experience. Thank you.
We hired McMaster to replace our entire HVAC system with a new heat pump just days before Christmas, and the experience could not have gone more smoothly. Every person we interacted with was friendly, knowledgeable, and genuinely professional. From the first call, to the installation, to the final city inspection, the process was handled with care and competence at every step. We’re extremely pleased with both the quality of the work and the way McMaster managed the project. We highly recommend McMaster Heating and Air for anyone needing HVAC service or replacement.
Great work!From the beginning of the project to its completion, I have been truly impressed with the exceptional level of customer service provided by McMaster Heating & Air Conditioning. Your team’s professionalism, communication, and attention to detail made the entire process smooth and stress-free.
I reached out to get 6 different quotes from 6 different local air conditioning companies and after the first meetings I was quickly able to narrow down my search to just two companies. the bad companies were really bad when compared to the two that were in the running which included McMaster Heating and Air. I decided to try to use both Home Depot and Costco to see if they were a good option and let's just say they were the biggest scammers who almost doubled the rate I received and used high pressure tactic's. I am a seasoned sales person and I would not wan those people anywhere near my mom or grandmother.I was open to using gas or electric and I decided to take a chance on electric vis gas because I had solar and power walls that could keep me going in the event of a power outage. It did require that I added a dedicated 220 in my attic where the furnace was location and they did it without needing to add any wires on the outside of the house (important to me).Installation took just 1-day and they had their whole team working together like a well oiled machine. The quality of the work was impeccable and they were kind and used booties coming in and out of the house. They even brought a wench to get the old air conditioner out so they could put the new one in. I needed to use my neighbors yard to wench it over the wall and zero issues given how well staffed the job was.After everything was installed there were two additional issues they set up for me. Something called a HERS report that is required now in the state of CA where an inspector comes out to make sure that everything was installed properly and the air is blowing within specs and the items that were installed were the ones I paid for. Afterwards they also scheduled the city inspector to come out who was only here for about 30-mins while he confirmed things like the 220 dedicated power in the attic was indeed dedicated power.Lastly they also set up and did the paperwork for me to make sure that I get the remaining rebates back from the government given I selected the higher cost but more efficient electric option. Overall I could not be more impressed with the team, and the owner who talks like Sam Elliott. When I met the owner it pushed me over the opt and I knew that I needed to work with them. He was kind and trusting and assured me that everything was going to be OKI. They were not the cheapest or the most expensive and there pricing was right in the middle. Going to rate them 5 stars and hope I can work with them again.
