Signs You Need Commercial HVAC Repair Service Los Angeles
As an entrepreneur or administrator of a facility, it is crucial that your commercial HVAC system is efficient to the day-to-day activities. As soon as your system starts indicating that it is time to wear out or be inefficient, you can avoid expensive breakdowns, use of power, or unpleasant interiors. The following are the most typical and dangerous indicators of the fact that commercial HVAC repair is required in Los Angeles:

Inconsistent Indoor Temperatures
When other parts of your building seem to be warmer or colder than others, then your HVAC might not be able to distribute air evenly. This may be due to blocked ducts, malfunctioning thermostats or failure of some of the parts including dampers or fans.

Unusual Noises from the System
HVAC systems used in commerce are normally quiet in operation. When hearing banging, grinding, hissing, or squealing, it could be related to loose components, broken blower motor, or leakages of refrigerants.

Rising Energy Bills
Your utility bills might suddenly rise without any explanation and this could be a warning sign. As your HVAC system wears out, gets clogged, or includes inefficient components, it must consume more energy to keep the set temperatures.

Poor Airflow or Weak Vent Pressure
In case you find poor air flow through vents, the issue may be in the air handler, the air duct, or the filters. Lack of airflow hinders the comfort and creates an extra burden on your system, which causes premature breakdown.

Frequent System Cycling or Shutdowns
When the HVAC system is turned on and off often, particularly during periods of high humidity, short cycling may have a huge impact on energy efficiency and comfort. It frequently shows a fault inside or excessively big/too small equipment to your building.

Hired AOL to replace our old condenser and gas furnace with a new heat pump and air handler. Their quote was very competitive and though we ended up having to go with a more expensive unit due to size constraints and other reasons the total was still very reasonable. They did a great job and were responsive whenever we needed to get in touch. Can recommend.Posted on Google Roxana ZybleTrustindex verifies that the original source of the review is Google.

EXCELLENT Based on 210 reviews Posted on Yelp Jeff R.Verified Called AOL on NY Eve for my Dad's house in Granada Hills (I live out of town) ...he's elderly and his Caregivers told me the Heater comes on but the house isn't getting warm. Lisa answered the phone and checked the schedule to see if they could come out the same day....within 30 mins she told me Joseph can stop by...he then called me and told me what he needed to to, he did have to go back to his shop to get a part he returned to install it and replace some old wiring. He tested everything out and within 3 hours from my first call the house was warming up again. We found the cost to be reasonable and are quite happy with the service. I would use them again and can recommend AOL too. THANK YOU!Posted on Yelp Josh B.Verified Highly recommended. 3rd company that I worked with and by far the best. Dean was on time, communicative, walked through the issues ahead of any servicing. Identified a critical CO2 leak issue that was unrelated to what I called about. Will definitely lean on them for any future HVAC needs.Posted on Yelp Jonathan A.Verified I called AOL on a Saturday afternoon, when my AC failed during this record heatwave. After some initial troubleshooting over the phone, Avi & Jose arrived the following morning and completed the repairs in 2 hours, despite some challenges. My AC compressor is a high-efficiency unit with some complex electronic circuitry. Avi & Jose have particular knowledge & experience with these models, fortunately. I appreciated their professionalism, availability, and quick response!Posted on Yelp Glenn B.Verified Promp, knowleagable, neat and courteous. Avi and his crew were terrific. I had a lot of choices... I'm so glad I chose AOL Heating & Air. They will be my go-to for my service needs. Highly recommended!Posted on Yelp Reed M.Verified Avi responded promptly to our call and came to our house the same day. He explained the quick fix and its disadvantages given the short useful life of our system( which I had previously researched and which was confirmed by multiple problems we had in the 7 years we owned this house). He gave us a very fair price for replacing the system without any hard sell, which we chose to do. The team came the next morning and had the old system out and the new one installed in 6 hours. They were professional, polite, clean and quiet. Avi came by mid-day and two days later to check the completed work (the intervening day was a religious holiday). Altogether a 5 star experience.Posted on Yelp Sally N.Verified Avi is the man!!!! He is a super nice person and knows his stuffs. Our Condenser went down and I cannot afford to replace a new system. He found me a way to get a new condenser and coil with very very cheap price. We never met before and this is our 2nd time doing business with him. He treats his customer as a friend rather than as a contractor. We are so lucky to find a reliable hvac contractor and he is a man of his word!!Posted on Yelp Darren W.Verified AC stopped blowing cold air on Saturday of a major heat wave. They came out by early Sunday morning and fixed the system in 30 minutes. Super responsive and saved the day! They were responding to every AC emergency on Sunday when other companies said they couldn't come out until later in the week. If there were 10 stars I would give it to them. Thank you AOL!!!Posted on Yelp Melanie T.Verified Avi is the best. Great prompt service. Highly recommend. We were totally without AC and he he fixed our problem.Posted on Yelp Yadi S.Verified I was told during my last AC maintenance that our system was very dirty and needed a deep cleaning so that our system could operate efficiently. They provided a quote... and I was stunned at the price AND how many components needed cleaning! Decided to check Yelp for reviews and AOL stood out. Reached out to AOL and Joseph came out at the end of day to review our needs. I decided to hire them and couldn't be more pleased. They arrived on time, Jose greeted me upon arrival. Both Jose and Carlos were very professional and answered my questions during the service. I highly recommend AOL and plan on using their services in the future.Posted on Yelp Peter S.Verified AOL installed 2 new mini-split systems. The old ones were installed incorrectly, and they explained why and provided a few options on new systems and installations. Very good communication and service!
FAQs
Frequently Asked Questions
What kind of commercial HVAC systems does AOL Heating & Air Inc. maintain?
We deal with everything, such as high capacity rooftop units and packages, to advanced Variable-Speed Variable-Frequency (VS/VM) units and chilled-water loop systems. No matter the type of building that you have, be it split system, central plant, or a hybrid, our technicians are qualified to diagnose, repair, and make the best out of it.
What is the schedule of routine maintenance and why?
All you need to do is call us or access our online portal and make an appointment with us to maintain your vehicle quarterly. Routine tune-ups ensure that your equipment performs at its optimum efficiency, can identify the small problems before they turn into an expensive mistake, increase the duration of the components, and allow you to predict surprising shutdowns – which cannot be afforded by businesses that cannot afford a cold floor or red-flagged temperature gauge.
What are my emergency support resources in case of a failure of my HVAC system?
Our 24/7 emergency hotline ensures that there is a response in less than two hours in case of a commercial site. We will send a mobile repair team with diagnostic devices and spare parts hence you will be on schedule before your clients notice a hiccup.
Do you have any energy-upgrades or rebates you can assist me with?
Absolutely. We will evaluate your existing system, suggest high-efficiency improvements (such as smart thermostats, variable-speed fans, or ENERGY STAR-certified compressors), and help with the paperwork of local rebates or tax credits, or utility incentive programs. We aim at saving your operating costs coupled with enhancing comfort.
What are your guarantees to installed equipment and labor?
Every new equipment is supplied with manufacturer warranty of 2-10 years based on the product line. In the case of labor, we will provide a 90 days workmanship warranty on any such installation or repair performed by us. In case anything may go wrong in that window, we will correct that at no additional expense. In addition, we reveal all the warranty conditions at the beginning to ensure that you are aware of what you have.
