  • Measuring compressor and blower motor amperage

Tips for Choosing an HVAC Contractor

Choosing the right AC company for your needs can be overwhelming, and you don’t want to make the wrong decision when you need help fast. Take some time before you need service to consider the following factors:

  • Recommendations: Obtain referrals from friends or neighbors who have been in similar situations before. They should be able to recommend a technician or HVAC company they know will do a great job for you. Regardless of how highly someone recommends a contractor, however, you should still consider personally interviewing them.
  • Experience levels: Experience in the industry is another important factor that you must check. Get to know how long the contractor has been in the industry and how long they have dealt with similar issues. Experienced HVAC technicians are most likely to know how well to handle your specific project.
  • Cost of services: Before you hire an HVAC technician, it is important to evaluate how much they charge for their services. Rates will differ depending on the quality of work, experience, and the type of fee charged (hourly vs. flat rate). Evaluate quotes from different heating and air conditioning companies and then determine which one is more reasonable with respect to the scope of your project. Keep in mind that if one quote is much higher or much lower than the others, you may want to question why that is.
  • Licensing: Most importantly, before settling for any service provider, you should request to see their licensing documents and insurance bond. Licensing will help you separate reliable HVAC companies from others while the provision of insurance-covered services will protect you in case of damages done during the project. You can also check the license number given to know if there are any cases filed against that contractor.
  • Reputation: The reputation of the contractor in the industry will tell you a lot about their services. Read reviews from past customers to get a sense of whether customer satisfaction is important to the company. If it is established that most people have a good opinion of the contractor, their services are most likely to be of good quality.

Great overall experience

Review of Dial One Johnson Plumbing

A great overall experience from beginning to end. I appreciated all of the time Daniel took to examine my existing system, ask questions and make recommendations on a replacement. It was clear that not all companies are willing to do that. The installation team showed up on time and worked quickly to remove the old system and get the new one into place. Everyone was very nice and professional, I highly recommend the entire team.

Review of Dial One Johnson Plumbing

I don't write reviews. So, you must know this is a really good company for me to be taking time to write this... We've been home owners for 20yrs. We've used so many different plumbing companies, it has been exhausting wondering "are they going to do a good job? are they ripping me off?" Dial One Johnson was recommended to us by a neighbor and they are TOP NOTCH! We've had them out to service sewer line blockages (old house, roots growing, yuck but they solved the issue!) and now a broken water heater issue. In all service experiences, the guys are professional and patient. They take time to share their knowledge in layman's terms, which I completely appreciated! Their service fee is the lowest I've seen, so I felt taken care of (not taken advantage of). The Gals who manage the calls are so polite, always cheerful and work to get a service provider out as soon as possible. And best of all, they have a REALLY affordable yearly service/maintenance plan that I am signing up for- because it comes with all kinds of savings and PEACE OF MIND- that I now have professionals taking care of my plumbing, heating AND AC needs! HIGHLY RECOMMEND this CompanY!

Great service very informative awesome

Review of Dial One Johnson Plumbing

James did a wonderful job

Above and Beyond the call of duty!

Review of Dial One Johnson Plumbing

James came to a rental property with very unique plumbing issues several times. I live out of town and he continually sent me pictures and called me with issues. I SO appreciate his dedication and persistence. He thought “out of the box” and was able to fix everything. He spent lots of time, did great work and prices were reasonable. He was there until 6:30 on a Friday the first time he came. Thank you James and Dial One Plumbing. You are my new plumbers!

Response from Dial One Johnson Plumbing:
