"

It took 5 days  and went very well.  Jesus and Juan were hard workers and nice to have around. 

When Duke initially evaluated the house, he pointed out some reasons the old furnace system was inadequate and corrected these problems so the house now heats quietly and evenly, which is a nice change.  2 of the air returns were redone and an additional one added to improve circulation. The associated ducts in the attic were upsized which also helped. All the old crawl space duct work was replaced with a modern version and the associated register covers replaced..

"My mother's house had air conditioning that was improperly installed so it wasn't really cooling anything but the bill was still running pretty high. So basically there was a leak in the duct. I would use them again for air conditioning."

"Air conditioner was blowing ambient air only. Tried to contact my usual HVAC company and they were scheduled out 3 weeks because of the recent heat wave. I called 14 companies to check on availability and Comfort Energy was the only one who had an opening within the week. I confirmed with them and was very pleasantly surprised. They confirmed not only the day and time, but also the exact make, model, ans serial number of the unit to ensure they had all the information they needed. In the meantime, my husband was able to get the unit going by installing a new capacitor himself, which he had done in the past, but wanted to go ahead with the service call so we could have the whole system checked out in case there were other issues. The day before the appointment, I received a text confirming the appointment time. I asked that the service technician call 30 minutes before arrival, which he did. The technician, Nasser Pineda, is a fine representative for his company. He was polite, respectful of both my husband and me, and took time at the start of the service call to go over what he would be doing and how he hoped to provide us with the best service we had ever had. He said that the goal of Comfort Energy was to provide us with service above and beyond expectations. He did not fail us. He even wore booties so that he did not track dirt into the house. My husband followed him around asking questions and he was patient and knowledgeable. Nasser also told us about their yearly service plan which would ensure service checkups before the heat of the summer and for the heater before winter cold months. That, plus the guarantee that we would get priority appointment times even during heavy demand, has clinched our participation. Nasser and Comfort Energy know how to do it right; ensure that the client doesn't want to go anywhere else for their HVAC service."

"Jorge, Angel, Ishmael, and George were fantastic. Jorge was honest and straight in the initial conversations. He gave me multiple options for systems and their functionality. When I made my selection I was given a very fair price for the work that was to be done. He was very helpful in acquiring good financing that bested my Credit Union and Bank. The work was done quickly with great attention to the fine details. I now have an efficient and functional HVAC unit. If you need repairs or a replacement HVAC system you could not do better than selecting Elite Heating and Air for your job. I'm telling all my friends that if they need any work done - "I've got a guy"..."

"I highly recommend Aire Serv of Campbell & Saratoga to anyone in need of HVAC services. Alton helped me find the right system that works for our home within my budget. Alton was knowledgeable and truly explained the different options & HVAC available that would fit for our home. Alton answered all my questions with patience and expertise. The installation crew (Rene & Julio) were on time and explained the complete removal our old system and installation of the new HVAC. They treated my home with respect, cleaned up thoroughly after the job. I like their attention to detail and commitment to doing the job right the first time. Thank you for making our home energy efficient. I'm happy with the results."

"Rittinger responded quickly. Alan, the tradesman they sent over was professional and quick. I hired them to install a clothes dryer vent and to open up a vent in my garage for the hot water heater. The work was high quality and installation was clean."

Heating and Air Conditioning questions, answered by experts

It’s normal to hear a low humming sound as air moves through your vents. Most of the time, you probably won’t even notice it. However, if that sound becomes disruptive or if you hear more concerning noises (such as rattling, clicking, banging, hissing, or grinding), there might be a problem with your HVAC system.

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.
