"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"If I could give Cencal 10 stars - or 20 - I would! This is an ethical, compassionate, caring company owned and staffed by people who act out the company's ethos. Five years ago, when we needed a new dualpac in the middle of a cold winter, we shopped, and then chose Cencal for its responsiveness, clear information, and very competitive pricing. The installation went like a dream, and the service techs spent an entire morning at our home ensuring everything was working better than perfectly. The unit was under contract for a couple of years, and we decided to continue the contract when the "free" servicing expired. So worth the money for the peace of mind knowing our investment is being cared for by responsible reliable folks. I don't have a favorite tech: I appreciate all of them! They show up on time for appointments, and are universally businesslike and friendly. Thank you, Cencal, for making me comfortable in my home. (I'm not mentioning costs because I'm sure they're variable, but I'm on a fixed income and the service is affordable.)"

"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.

I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

"Had Tim out and his guys to replace and move my system. Moved all my duct work from under the house to above the house I hated having the vent on the floor! Also moved my system from a closet in my kitchen to the attic which gave me more space to expand my pantry! The guys were all polite and would clean everything after their work day! They did a great job with all the work! Would definitely recommend Tim and his team!"

"Fermin was very thorough servicing my air conditioning unit. Didn't rush through the job like previous companies I had hired. I appreciate that he took the time to explain EVERYTHING to me about my unit in a way I could understand! I will be using Nova for all my future service needs!"

"Very professional and honest, work completed in a very timely manner. Did not try selling us things we did not need. Informed us on the different type of units and what each unit would do for us and let us make the choice we felt would be right for our home. After having lived in our home for 6 years and having issue every summer and winter with the unit we had not heating or cooling our home and a pg&e bill upwards of $600 in the summertime it is amazing to have a cool/warm house and a bill that is quite manageable. Thank you again for the wonderful job!!!"

FAQs for swamp cooler service or repair projects in Modesto, CA

A well-maintained swamp cooler can last between 10 and 15 years. Its longevity depends on usage frequency, water quality, and proper care. Regular maintenance, like winterization and protective measures, can preserve your system's efficiency and prevent premature breakdowns, ensuring reliable cooling performance over its lifespan. Hiring a professional to take care of any repairs over your swamp cooler’s lifespan will ensure it’s restored to proper functioning and can help it last longer.

You should consider replacing your swamp cooler if it shows signs of severe corrosion, inadequate maintenance, advanced age, restricted airflow, or ongoing leaks. When repair costs and performance inefficiencies make restoration impractical, replacement may be the best option. Evaluating these issues with a professional ensures you choose the most effective solution, preserving comfort and cost efficiency while avoiding further deterioration of the system.
