Our Customers testimonials

It was just before a heat wave and our Air Conditioner was at 10% and could not drop a degree when on. I called and was scheduled the same day as they prioritize system down tickets. It was also a diagnostic call. Cory our tech, checked the AC and furnace and quickly found an additional dirty filter that has fallen in and blocked the air flow when coupled with a new one I put in. This made the coils ice up. He was very thorough in the repair, adding coolant, fixing a small leak, cleaned the coil, and explained all to me every step of the way. he was there a couple hours and total including all parts (leak stop process) was well under $400. He did not try to sell me a new furnace or AC unit, which I was prepared to fight off if needed. I thought the price was very fair and the experience was excellent for a change when calling on service companies you have not used before. Highly recommended! (We are in Glendale)

K Komfort just installed a new Carrier Infinity furnace/AC and tank-less water heater. The owners showed up early for a service call and validated the 30 plus year old furnace was on it last leg, they were able to schedule and replacement within 48 hours. K Komfort installed everything in one day and had me back up and running to perfection within 8 hours. They brought in 2 crews one to work the furnace/AC and the other to rip and replace the dead water heater.

We just had our complex HVAC system repaired and zoning installed They were polite and helpful on the phone, returned calls, and scheduled servicing promptly. They came when they said they would. Euguene, did a thorough job, explaining what he did clearly, explained what the problem was and how he fixed it, and what to look for in the future. This was a big improvement over our past service company who kept saying there was nothing wrong with our system and nothing can be done to fix my daughters cold room. I don’t know how they could have given us better service. They are very reasonably priced, Absolutely nothing to complain about, the high quality of service and skill we received from them and very reasonable price.

We hired K Komfort for our cooling needs. The prices were reasonable and Eugene and his team were both efficient and pleasant to work with. We will most certainly use them again in the future and recommend that anyone else do the same.

-Courtney H.

When we experienced an unexpected failure of our heating system which resulted in a carbon monoxide alarm, representatives from K Komfort quickly arrived at our residence to assess the situation. After finding and explaining the cause, they offered the option of repairing the existing furnace, or replacing the unit altogether. We chose the replacement option. An installation technician arrived with a new furnace shortly thereafter. His pride in workmanship was evidenced by his obvious knowledge of relevant codes, as well as his fine attention to detail. The job site was cleaned up after completion, the system was thoroughly checked for proper operation, and the old furnace was taken away for recycling. We highly recommend K Komfort for all of your heating and cooling needs!

K Komfort replaced my furnace and added a humidifier back in December. After 4 months of living with the system I am very satisfied with K Komfort. I would not hesitate to use them again and would certainly recommend them to anyone in need of HVAC service. I found the their recommendations to be helpful and honest. Installation was on time, courteous and very professional. The installer took the time to show me what was done, how it was done and how to use and maintain the system. All sheet metal and electrical work was done with a very high quality.

When the winter kicks in and you get your furnace turned on first time this year, do you have your fingers crossed and hope it will start? You don’t have to! Just watch this simple tip and make sure your exhaust and intake pipes for the furnace are not blocked. Do you cover the pipes to make sure the leaves and small animals don’t get in? Don’t forget to remove the covers before the heating season. The same issue with the exhaust and intake pipes may occur year round on your high efficiency water heater.

 How do I know if my air ducts need to be cleaned

  • Do you or a member of your family have asthma or allergies?
  • Do you have small children or pets?
  • Has it been 5 or more years since you cleaned them last?

 Bacteria….viruses…allergens! What do these all have in common?

They’re all easily spread and continually circulated by poor air quality throughout your home!

The quality of air you breathe in your home is vital to the health and well-being of you and your family. Dirty, dusty air ventilation systems within your heating and cooling ducts can promote sickness by spreading bacteria and viruses, and may further complicate chronic conditions such as asthma and allergies.


 Suggestion for humidistat settings

Maintaining a proper humidity level in your house is very important for the following reasons:

Health issues and comfort level. We are used to having dry skin, bloody noses, and constantly being shocked by static electricity. All of this is an indicator that the indoor humidity is too low. Unfortunately, it doesn’t stop at being uncomfortable. Dry air may aggravate allergies, asthma, sinus infections, and ear infections. Dry air also aides in the transmission of viral diseases.

Home damage. Wooden floors, window frames and doors, furniture and especially musical instruments (e.g. pianos) are very sensitive to the humidity levels. Wood can absorb or release moisture quickly, which leads to changes in the weight and shape, and may cause permanent damage. When the humidity is too high, moisture condensates not only on the windows but also inside the walls which promotes structural damage and growth of mold, algae, and bacteria.

Energy efficiency. “It’s not the heat, it’s humidity” even though this statement is generic, it is in fact an accurate statement. To get a bit more technical, it is temperature, humidity, and air quality combined what define the comfort level. In general, a person may be comfortable at 78F as long as the relative humidity is below 45% or at 68F as long as the relative humidity is above 35%. When the humidity is out of the “comfort range” we try to compensate by raising up the temperature in the winter or overcooling in summer. This leads to higher energy bill.

So what should a humidistat set at during winter? The answer is… it depends! Unless you have a “smart humidifier” which is able to adjust the humidity level based on outdoor temperature, you have to do it manually. Below is the chart which will help you properly adjust your humidistat.


 Recommended Indoor Humidity Levels

Outdoor Temperature, F Recommended Humidity Level (%RH)
+40 45
+30 40
+20 35
+10 30
+0 25
-10 20
-20 15
