Services
Under normal circumstances, it has been found that humans spend nearly 90% of their time indoors. Each household and commercial building is exposed to one, if not more, of these pollutants everyday. However, this is not necessarily a bad thing. All it means is that it is vastly important that each property owner takes an elevated level of care and precaution when it comes to regulating and maintaining proper indoor air quality.

We had a problem with our heating unit giving off a distinctive smell. Noel from Baseline Heating and Air Conditioning came on time and followed COVID guidelines wearing a mask. He was thorough when checking our unit making sure where the hazardous smell was coming from. He explained what was wrong with our system and fixed the problem. Before he left, he made sure everything was working well. If you have any problems with air conditioning and heating I recommend him. In the future, I will be calling him to get service on my AC system. Noel was professional, friendly, skilled, cautious, and inexpensive

Loved that they showed up in a mask and were timely, efficient and effective! Very good communication and my issue was resolved expeditiously. I would definitely recommend their service and would use again.

This is the place to go for all your HVAC needs.
Was having an issue with my Nest thermostat a few months back and Nest/Google arranged to have a technician come out and fix it. Noel from Baseline arrived and took care of the problem, did a very clean repair (installed a common wire), and was an all around great guy who clearly knows his stuff. Took his card and figured he would be the guy I call if I ever need service on my furnace or AC. Fast forward to last week and my AC stops working at my house. I knew the AC unit and furnace were 20 years old and on borrowed time and would need to be replaced

Exceptional beyond my expectations! Thank you Noel!

I had called several other companies for evaluation and estimates. Noel won my business because he really cared about my situation and worked hard to find a good quality condenser and coil at the price range i could afford. If you are looking for a reputable company, putting customers first, I would go no further, Noel's team delivered above and beyond my expectations.

Throughout the process, i was briefed on the next steps and expectations. Noel was eager to educate and encouraged to ask questions. He kept communicating promptly via

Just had Noel from Baseline out to our house. Very prompt response and called to say he could come earlier than expected. No extra charge for the weekend. He thoroughly assessed our situation and found the issue. We were so afraid it was going to be a huge expensive problem but he figured out what we needed and it was very reasonable. He also is familiar with Nest thermostats and was extremely knowledgeable about how they work and are wired. In addition he was wearing a nice uniform, mask (quarantine time) and wore shoe covers while in the house. Super happy with today’s service: professional

Our ac stopped cooling. With this current heat wave we had no choice but to call a tech to come out. I checked out various companies but decided with Baseline due to the reviews and proximity to me. Noelle came out on a Saturday first thing in the morning. I gave him a quick description of the issue and he knew right away what the issue was with our ac. A leak. He checked other components to make sure it indeed was a leak. Unfortunately it was. He offered a variety of options with an estimated price to each one. Not being cheap but I went with the cheaper one for the quick fix at this time (family

We just had Noel from Baseline heating and A/C come out to fix our heater. The heater worked but would not heat up. Noel diagnosed the system which is 30 yrs old and determined that the gas valve needed to be replaced. The original gas valve could not be found, but he was able to find a replacement which required a new configuration and setup which worked find. Not only did he replace it, but also tuned and optimized it. The price was very reasonable and he told us what the cost would be before he ordered the valve. I am so pleased with his honesty and service ethic that I will send all my

Noel contacted me on a Saturday evening in response to my heater being out of commission. He arranged to make a house call the next morning to try and get our heater working. As it turns out, the problem was easily resolved and Noel shared some important information to keep our furnace running efficiently. Most, if not all other, technicians would have kept the information to themselves and charged an outrage amount for a Sunday morning house call. We were charged only for the house call. Noel spent time at our house to make sure the heater was operating properly before he left. I don&apos

Wow! Noel Ahumada is amazing! I needed my ecobee4 thermostat that I got for free to be install but every other company was charging around $200. Very pricey. Our a/c and heater was broken so there was no point. Noel contacted me , and I let him know we couldn't afford it. He was very understanding and said if we gave him a chance he would only charge us $30 . Too good to be true? Not in this case. He came through. He installed our thermostat. He saw that our a/c wasn't working and he changed and installed new cables. He also fixed our heater. If that wasn't it , the transformer

Noel Ahumada from Baseline Heating and Air Conditioning was outstanding to work with as he was professional, courteous, knowledgeable and had a great sense of humor. He arrived to the appointment on-time and instantly was able to diagnosis any of my HVAC problems or concerns. He was such a pro that he even went up and down a 20+ foot ladder to service my HVAC rooftop package several times in one visit in the San Fernando Valley heat with no complaint whatsoever. Noel is coming back for another fix next week and I can't wait to work with him and Baseline Heating and Air Conditioning for any

Super reliable! Our heater went out last week and called another local company out to fix it, the other company was able to diagnose a bad circuit board but said they had to order the part and would return the following day. The other company never showed at the time arrange and called to reschedule for the following day. I decided to call Baseline since we have little ones at home and I didn't want to wait any longer. Baseline was able to send someone over the same day, diagnose the issue, pick up the part and repair the issue all in the same day. All that for close to half what the previous

My downstairs heater stop working right before the holidays, and I needed to get it fix quickly since the family was coming over for Christmas. I found Baseline Heating and Air Conditioning online and saw they had a diagnostic charge of only $50 (which I liked) so I gave them a chance. They set me up with a service call the same day and they sent their Service Tech Noel. I liked this company from the moment they stepped in the door, Noel was very pleasant and used floor savers in my home. He quickly diagnosed a bad "hot surface igniter" and luckily had one in stock in his service van
