San Angelo Plumbing, LLC is dedicated to your plumbing needs. We bring tip top quality work to each one of our projects, and will stay until the project is at your satisfaction.

"They did a great job installing a new hot water heater in 2015. In 2021, I noticed water at the base of the tank (possibly a problem with the drain valve). I filled out the online service request form but did not hear back. In the past three weeks, I have called the service line, and cell phone number listed on their profile several times. I was able to leave a message once (approximately two weeks ago). All other times the voice mailboxes have been full. I have not received any response to the online service request form, nor the phone message I left. It is disappointing and frustrating to spend 1k on a hot water heater, but then simply not to be able to reach anyone or get a callback. If the business is shuttered or overwhelmed for any reason, it would be professional and appropriate to post a message to that effect, at the very least."

"My review for my service representative & the company MAXAIR LLC. Steve, was my representative for the service call and he arrived within the time slot that I was given. He was a very helpful & a nice guy. He got my humidifier working. As the digital panel had a light flashing to replacing the water panel on humidifier. He had the filter with him so he was able to replace the water filter panel. I set up a full service call on my furance. I was glad that I did that to get my furance ready for fall/ winter. He said showed me where to replace the furance filter. Then I decided to take advantage of the service plan that they offered.

"Joe was fantastic in resolving these repairs at my mother's 100 year old house. Working through a federal program for funding, Joe provided the estimate quickly and within budget. He was able to find era-appropriate flooring for the porch. He also installed much safer handrails on the steps up from the street to the porch and corrected the unsafe side entry by installing a sturdy platform and step. I will hire him for any of the items I need done at mom's or my house. Thanks Joe and crew."

Heating Oil questions, answered by experts

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives). 

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.
