I was very satisfied with the work performed and the professionalism of the crew.I used DG Heating and Air Conditioning (San Jose CA) for my recent install of air conditioning at my home near Redwood City. I got three other quotes for the work, and DG was actually the best price. I was very satisfied with the work performed and the professionalism of the crew. I was astounded at the amount of work that the crew of three accomplished in just one day. They did a good job of cleanup and the system works great. This was a job to add an air conditioner to my central heating furnace. Working in a cramped dark attic is tough, and they had to move some heavy things around. I give them five stars and a good recommendation. The system passed duct pressure test and inspection by San Mateo County on first try. Now I have cool air in my home at the touch of the controls of my existing thermostat. Ready for a hot summer, thanks guys!

I'm so grateful to all of you not only for your timely and professional service but also for the reassurance and peace of mind you gave me
Many thanks for the assistance you and your employees provided during my power outage last week. John re-routed circuits to keep my refrigerator running during the three day interruption in service and turned off the condenser to prevent damage in case of a power surge. Brian immediately identified the course of my failure as a missing band and talked directly with a PG+E service representative. The office staff kept me informed about scheduling and appointments.
I'm so grateful to all of you not only for your timely and professional service but also for the reassurance and peace of mind you gave me during the four days my power supply was compromised.

The Whole Experience Was QualityI live in a neighborhood of DG Heating and Air Conditioning customers. In 2017 during a renovation, DG moved our furnace to the attic, and then in 2018 DG installed an AC unit for us. From the estimator, (John) to Leticia in the office, and then the competent technicians, we have been very happy with the product and with the team of people that make up DG. The whole experience was quality plus.

Would Recommend DG to Everyone We KnowWhat a great experience with DG! John came out to our home to give us an estimate and we really appreciated his knowledge and honesty regarding possible findings and costs when they went under the house. Once we set a date for the work, Mike came by for a walk through and was extremely knowledgeable and answered all our questions. The crew, headed by Roy was punctual, efficient and so nice to interact with! We would recommend DG to everyone we know!

Knowledgeable & Easy to Work WithDG has installed my complete HVAC systems. All work perfectly and without issue. Their staff is knowledgable and easy to work with. I recently had DG install a new tankless water heater. I was able to interact with their team on the pros and cons of the latest heaters on the market, which helped me select the right product for us. No pressure for any preferred brands. Installation of the heater had several challenges, all resolved professionally and efficiently. Great service!!

Quick, Fast, Efficient WorkDG has always taken care of me when I needed tune-ups on my old system. So when I finally decided to bite the bullet and replace everything(ducting, a/c, furnace), I didn’t even get other quotes. In this day in age, with businesses cutting corners to maximize profits at the owner's expense, it's quite an enjoyment to hire companies like this who do perfect work, finish quickly, and clean up every day as if they were never there. Big thanks to John, Mike, Roy, Leticia, and all other installers who did an awesome job on my HVAC system.

A Job Well DoneDG heating and air conditioning company gave me an exceptional experience last year. They upgraded my home air conditioning system using excellent workmanship and a very competitive price.
After spending my entire career in the industrial air conditioning industry, I was very impressed with DG's workmanship and professionalism. Thank you, DG for a job well done!- John W.

Amazing WorkWe purchased a new, two-level home last spring that had an inefficient heater, no air conditioning, and asbestos within the existing ductwork. We received multiple bids from other contractors but went with DG and will continue to work with them for our heating and cooling needs in the future for a variety of reasons.
First, John did a thorough evaluation of our needs and offered a comprehensive plan to address each concern including the abatement and removal of the concerning ductwork. Second, due to the narrow nature of our lot and offset regulations we were forced to use a compact cooling unit. John and his team made sure the unit not only fit into the plan but also made it as ascetically appealing given the less than ideal location. Third, the abatement subcontractor they partner with and the DG installation teams could not have been more professional and detail oriented. Fourth, the level of continued service post-installation has been exceptional. Early this winter, our heater would not turn on. I called John and within thirty minutes a member of their team was out addressing the issue. John took the extra step of swinging by later in the day to make sure that the furnace was operating fully post-repair and additionally checked back in a few days later via phone.
I cannot recommend DG Heating & Air Conditioning enough!- Michael K.

Fantastic ServiceDG's service was fantastic. Response to questions was fast. They Delivered product and service as promised and on-time. I normally don't write reviews, but great service deserves great praise! DG came in and exceeded all expectations, they are so thorough. I honestly refer them to everyone I know. I'm sure anyone that uses them will feel the same. If I ever need another AC to install or have any HVAC issues I know exactly who to call! Their continuous service has also been fantastic. I have nothing but good to say about this company! You will not be disappointed! Thank you, Mike and team!

I'm Only Calling DGExcellent contractor, I highly recommend them. Our furnace broke in freezing temperatures on Presidents Day. Despite the holiday, DG was able to come out the same day and fix our issue. Their employees are extremely professional, courteous, and on time. Not only did they fix the issue, but they also educated me on the ins and outs of what happened and advised me on how to prevent this type of problem from happening again. On top of that, their rates were very reasonable for all of the services they provide. When I have any HVAC issues/needs in the future, I'm only calling DG.

Mike and his team installed my A/C system, and I couldn't be more pleased!Mike and his team installed my A/C system, and I couldn't be more pleased! It was a difficult installation, as my furnace is located in my attic, (VERY tight up there!), but everything was handled by his crew easily.
The crew was friendly, and paid close attention to keeping things clean.
Highly recommended!- Brian C.

Arrived On Time & Knew What They Were DoingI recently purchased an air-conditioning and furnace unit from DG. The overall experience was great. John, one of the owners, came out to my residence. He answered all my questions, made useful suggestions, and educated me on some of the intricacies of heating and air-conditioning units. We ended up purchasing a high-quality Bryant unit which works perfectly. The price was also quite reasonable. The installation, with three highly skilled technicians, took one full day. They arrived right on time, knew exactly what they were doing, and cleaned up everything when the job was finished. After the installation was completed, they showed me how to operate the unit and then we gave it a test run. It worked perfectly! After a few months, I decided to purchase an air-conditioning cover for my unit. I contacted DG who found the exact cover for my unit and personally delivered it to my residence making sure that it fits perfectly. DG offered great service, a reasonable price, a high-quality unit, and overall great experience.

Highly Recommend Their ServiceI was impressed with DG Heating & Air Conditioning from start to finish. From John coming out and answering my questions and getting the estimate to me on the same day. To the installers who showed up in time and we're prepared to start. They were professional but personable. They laid out drop cloths before starting and cleaned up afterward. They noticed a few things that a previous contractor missed/didn't do. They corrected these issues as part of their install. The inspector just signed off on the work with no problems noted. I would highly recommend their service.

On Time & Great ServiceThis is the second time I have used DG Heating and Air conditioning. They have always shown up quickly and done a great job. We had our Trane Air Conditioner serviced. They never try and up sell you, they just find the problem and fix it. He called when he was on his way, I didn't have to wait hours and will definitely call them again. Thanks!!
