Above all, we are watchful of our customers interests, and make their concerns the basis of our business.

"I called ThermoTech Solutions and they sent out a technician within 24 hours. I was pleasantly surprised that the technician was the same gentleman I talked to over the phone so I did not have to retell what was wrong with my system. Jason my technician who is also the owner was great. He tested my system, knew exactly what was needed, and had it repaired the very same day. He did not try to sell me on upgrading my unit or a bunch of repairs I did not need. The service was fast, very reasonably priced, and I have had no issues since. Will definitely be having ThermoTech Solutions come out for all my HVAC needs in the future!"

Home Appliance Repair And Service You Can Count On! We provide reliable appliance repair services. We fix all brands and types of appliances. Our goal is to make sure you get the best appliance repair service for the best price available in the market. We do not offer installation services.

"I booked a deep clean for my Viking BBQ after confirming they had experience and would thoroughly clean/inspect the grill. Technician arrived on time but only dry-brushed corrosion for about an hour and left the inside still covered in brown dust. He couldn?t identify parts that needed replacing and the company refused to share part names, only pushing to sell replacements. He told Julia I expected sparkling. What they called a ?deep clean? was nowhere near what I requested especially because it wasn't clean. Seems like non-toxic cleaners could have been used. Felt like a bait-and-switch. I paid $150 (fair for what was actually done) but will not use them again. Photos are the condition after it was "deep cleaned""

Albert Nahman Services was founded in 1981 and has been serving Berkeley, CA and it surrounding areas in all their plumbing and HVAC needs. Each of our technicians went through rigorous training so we can guarantee that you will be receiving the proper service. We are also insured and supply a warranty for our parts for five years and up to twenty years on an re-piping or sewer replacement. Call us now to make your appointment!

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

This includes periodic cleaning of the unit, replacing filters or pads, and monitoring water levels to prevent black mold or bacterial growth. The frequency of maintenance tasks may range from monthly to quarterly, depending on the model and usage.

Regularly clean or replace filters, check humidity levels, and descale water reservoirs.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.
