I called Helms in response to a reminder postcard from them about my contractual checkup for winter. Scheduling the service was a breeze with Helms, being especially helpful in making sure time was available to service all three systems. The service technician was prompt and stayed additional time in order to complete the entire checkup. I found Helms after being very disappointed with another local company. Helms installed a new heat pump for me two years ago, and the system runs perfectly. If I have need for their services, they are prompt and always call ahead if they can make the appointed time or come earlier. Only once were they delayed, and I was called and made aware of the situation. I have an annual contract with this company, and am totally and completely satisfied with their work.
