Since 1996, Ragsdale Heating, Air, Plumbing and Electrical has worked to maintain our reputation as the name you can trust for your heating, cooling, plumbing and electrical needs. Our Ragsdale team is comprised of truly good people, who care deeply and are devoted to taking exceptional care of our customers, our community, and each other. From the people in our office to the technicians out on the road, everyone here is dedicated to 100% customer satisfaction. We are a family who treats you like family, and we are 100% focused on doing what is right every time, every day. Our goal is for you to take comfort in knowing that when you have a problem, Ragsdale is here for you.

"Although the technicians are very nice. As a company Ragsdale has failed us miserably. We spent about 18K to have our whole system upgraded and new insulation in the attic. We followed the recommendation of their sales person to the letter. He ASSURED us that in spending all that money we would not have any more issues cooling our home. Immediately there were more issues. The A/C unit they installed outside dies in 3 days. It was a lemon I guess. And when they went to replace that they also saw that the sales person didn’t notice that the circuit breaker was not the right one to handle the new unit. They had recommended we add new intakes in two rooms so we had done that as well. Like I said we did everything he told us we needed to do to solve any cooling issues. Still two rooms don’t cool well, my office and our master bedroom. We have reached out a few times and they send someone to look. Every time they have different recommendations from a second unit to another thermostat, tinting the windows, keep the blinds closed etc. I have tinted the windows and we keep the blinds closed, but another unit or another thermostat are just not things we can afford to pay for out of pocket. Two times I was told a supervisor would reach out to us but they never did. The guy today, again he was very nice. Said we should buy wireless sensors to connect to our thermostat so it knows to keep cooling. That’s another $100 out of our pocket. He said there should be a second cooling vent in our master bedroom as well. Yet another thing they didn’t recommend when we bought this system that we were assured would be more than enough to cool our home. All these things we would have considered and/or done if we were told they were needed when we spent the money. But the I think commissioned sales person didn’t really know what he was doing now. He was just looking to make a sale and didn’t care wether it actually fixed the issue or not, he got paid either way. Again today I try to call and speak to someone before I left this review. I sat on home for 5-10 min with the recording telling me my place in line and to hold to speak to someone. Just to get the general voicemail to leave a message. We are stuck with them now, they do the warranty work so they do the yearly maintenance to keep the warranty. But I would NOT recommend til his company to anyone right now. They have completely failed us and taken our money without actually doing what their sales person assured us would happen. Very disappointed avoid them for your own good"

I have been in the construction industry for over 25 years. As a homeowner needing to get things done that I do not have time to do, I tried to hire people to do the work for me. If I contacted companies, they did not answer the phone and if you left a message they did not call back. If they did call back or they would schedule appointments and never show up or if they did show up you would never hear from them again. If I was lucky to find one that provided an estimate, they did not know how to do the projects requested. Larger companies do not want to do the "little" things. At the point of getting so frustrated, I decided to start this business so that other homeowners would not have to go through this. I have hired professional and qualified people; drug test and background checks have been performed on them to ensure clients safety. The technician comes out, accesses the work and pricing is given on site. If pricing is accepted, the technician will perform the work immediately. You do not pay for the work until the job has been completed to your satisfaction.

"Customer service was superb and concise. The information about what was to be done was excellent. The handyman was experienced and completed the job in a timely manner!"

Heating Oil questions, answered by experts

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.

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.

DIY maintenance like filter cleaning is possible, but professional servicing ensures proper pressure, refrigerant levels, and loop performance.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.
