HVAC control systems come in different types with different elements. You have traditional analog inputs, pneumatic systems, digital controls, building automation systems, DDC systems, BMS building management systems, controller logic, and more. It can be a lot to handle.
But HVAC control systems are still incredibly important. These systems allow facility managers to monitor and control heating, ventilation, and air conditioning units, ensuring that they are operating correctly, meeting set points, and providing optimal energy efficiency.
If your facility is large and complex, then you may need a more comprehensive management system with multiple controllers and logic sequences of operations. On the other hand, if your needs are more straightforward, then you might be able to get by with simpler analog inputs and outputs.
So how do you evaluate an HVAC control system? Here are some factors to consider:
When it comes to evaluating and buying an HVAC control system for business and government facilities, there are several factors you must understand to make the right choice. You must consider them to ensure you get a system that meets your specific needs.
These 6 factors have consistently been present in my work with my clients at DPS. Aside from RTUs and central master stations, HVAC controllers are one of the most common device types we manufacture.
Let's go through these general buying criteria to keep in mind when shopping for any HVAC controller:
When you understand and utilize the above buying criteria, you can ensure that you choose an HVAC control system that meets your needs and improves the energy efficiency of your facility.
One option you have for your short list of HVAC control systems is the HVAC (Lead-Lag) Controller manufactured by DPS Telecom.
This controller can monitor and control up to six HVAC units for lead/lag operation and supports multi-zone buildings
It also comes with a convenient front-panel LCD touchscreen that enables technicians to run tests on each unit, configure controls and alarms, and see the status of all HVACs.
With regard to hardware I/O, the controller provides 12 general-purpose discrete inputs and 12 additional relay outputs.
The Lead-Lag Controller manufactured by DPS Telecom offers an effective solution for managing up to six HVAC units for optimal energy efficiency, cost savings, and maximum equipment life. You also get D-Wire support for dozens of daisy-chained sensors, making it a convenient and economical option for facility managers.
Let's now take a look at the time savings you can gain from D-Wire or any similar bus-powered and daisy-chainable sensors for use in remote facilities.
D-Wire sensors are a crucial component of the DPS Telecom HVAC control system. These sensors allow facility managers to track the environmentals (ex. temperature, humidity) of their telecom shelter using convenient daisy-chained sensors.
With D-Wire sensors, managers do not have to worry about analog capacity on their HVAC controller or a tangled mess of "home runned" wires. The sensors use simple RJ12 connectors, which enable daisy-chaining dozens of sensors to a single DPS HVAC controller's D-Wire ports.
You can run the sensor chain for hundreds of feet, monitoring the equipment's temperature and airflow output of each vent and multiple ambient room temperature and humidity sensors.
When you buy a HVAC control system, it needs power to work. Popular options are -48 VDC, +24 VDC, or 110/220 VAC.
By matching your device to your available site power (or using an AC wall transformer as needed), you'll avoid the need for additional installations or the need to return a purchase for something else.
This is why, at DPS, we commonly manufacture our devices in -48 VDC, +24 VDC, and +12 VDC build options. Some wide-range power inputs can even span two of those nominal voltages to give you flexibility.
As you can probably guess, I do this kind of thing a lot. Remote monitoring and control devices are the only thing we do at DPS. Over a span of nearly 40 years, we've learned most of the ways you can go wrong.
I encourage you to use this article, and the rest of the DPS website, in your search for your ideal HVAC control system. Depending on your needs, you may or may not need our HVAC Controller. It was designed originally for remote telecom huts, but the concept of cooling an enclosed space is fairly universal.
Choosing the right HVAC CRM (Customer Relationship Management) software for your HVAC business is one of the best ways to streamline operations, improve customer communication, and maximize your business growth.
As your HVAC business grows beyond residential clients and takes on more complex opportunities, such as commercial facility maintenance contracts, you’ll need the right HVAC CRM technology to scale with you.
With so many software solutions on the market, choosing the right HVAC CRM can feel overwhelming. That’s why knowing which questions to ask is essential to finding a system that aligns with your unique workflows, client base, and long-term goals.
An HVAC CRM (Customer Relationship Management) software is a specialized tool designed to assist heating, ventilation, and air conditioning businesses in managing their customer data, scheduling, service delivery, and communications.
You’re always going to be looking for a way to go above and beyond your competition and an HVAC CRM can help you accomplish this goal. The benefits of implementing an HVAC CRM include:
An HVAC CRM simplifies the process of managing customer data by centralizing all your information, including customer contact details, service history, and preferences, in one easily accessible location.
‘CRM stands for customer relationship management, which is a system for managing all of your company’s interactions with current and potential customers. The goal is simple: improve relationships to grow your business. CRM technology helps companies stay connected to customers, streamline processes, and improve profitability.’ (Salesforce)
This establishes a work environment where technicians have all the necessary customer information at their fingertips – aka: a single customer view – which enables them to provide a more personalized and efficient service.
By automating the storage and retrieval of customer data, an HVAC CRM reduces the likelihood of manual errors that often occur when having to manage the vast amounts of information a growing business needs to process and protect.
This feature helps maintain data accuracy, leading to improved customer service and trust in your services.
An effective HVAC CRM can automate the scheduling and dispatching of service technicians, ensuring that appointments are appropriately managed and allocated based on availability and proximity.
For example, let’s say your business submitted for and won a contract to manage the HVAC systems for a group of local chain restaurants. If they’re unable to access your schedule and request appointments when it’s most convenient for them, they might have issues finding availability that works for both your team and their hours.
Not to mention, they might need an emergency appointment if their AC breaks in the middle of summer. Having a digital scheduling system that can track and route the closest technician efficiently will keep you from breaching SLAs and make a great impression when the customer needs you most.
With access to customer analytics and service history, an HVAC CRM empowers your team to deliver more personalized services. When your techs have the customer details in front of them, they’re able to ask the right questions and get the job done with confidence.
This type of approach can help build long-term customer relationships and foster a positive reputation for your business within the local community.

Paper trails can make it tough to follow and track your payment process, so having an HVAC CRM that simplifies and automates invoicing will allow for accurate and timely billing.
Invoicing software is one of the fastest ways you can minimize administrative overhead and certify the billing system remains efficient and error-free.
A well-integrated HVAC CRM facilitates communication between your technicians, office, warehouse, and customers.
“One key aspect of CRM is the ability to centralize all customer information into a single platform, allowing businesses to have a 360-degree view of each customer. This integrated approach enables companies to tailor their marketing strategies, improve customer service, and effectively target specific customer segments.” (DataGuard)
It provides automated reminders, updates, and notifications, verifying that your customers are informed about appointments and promotional offers, leading to improved customer satisfaction and retention.
As an HVAC business owner, selecting the right Customer Relationship Management (CRM) software can significantly impact your operations and growth.
To make an informed decision leading up to the commitment, consider the following questions before investing in an HVAC CRM:
With the right HVAC customer database, you can manage work orders and send invoices directly from a customer’s account. This way, you maximize productivity by running multiple aspects of your business from one place.
The best software has features such as:
You can even look for a system that provides training for your business. Then the whole team is on board about how to best implement and use the HVAC software.
The best HVAC software stores the following data:
This one is pretty simple – you need a place to store the name, number, addresses, , and any other pieces of essential information for each client. That way, it’s easy to get in touch for any reason you may need to contact them (or it’s easy to identify who’s reaching out to you).
Let’s say a customer calls and wants a reminder about when their next appointment is. You can look through the calendar, but this may take a while to sort through and find their booking.
With an HVAC CRM that stores appointments against the contact, you can easily look up their appointments by simply searching the client’s name.
Job history helps you understand what type of work has been done at a property. Having this information for each contact is useful as it can help provide valuable context for future appointments.
Knowing what type of service has previously been completed, when it was completed, the parts used, and any photos taken allows the HVAC technician to accurately and safely complete the job.
Does your staff ever struggle to remember if they’ve already followed up with a customer? There’s no need to worry about it with an HVAC CRM that records communications – including calls, emails, and timestamped notes.
Securing reliable recurring revenue can only help your company’s bottom line. Service reminder software will help your team notify a customer via text or about when their next service is due.
Every HVAC business has data and information that is essential, like the specific number and location of assets you need to service under contract this month. It’s important that this data, no matter what it contains, is stored well and is easily accessible.
Having the ability to customize your customer database software allows you to put important information at the forefront of your search.
Getting appliance information from the customer can be tough if they’re unfamiliar with their systems.
The right CRM enables easy access to details about customers’ HVAC appliances, including model numbers, installation dates, warranty information, and any maintenance or repair history associated with each unit.
Have you ever lost out on a sale due to a lack of communication? It only takes one miscommunication to lose the trust of a client.
Assess whether the CRM has features such as automated appointment reminders, follow-up notifications, and personalized messages, to make sure you never miss an opportunity and increase customer happiness.
Tip: Staying in communication with customers after their work order is complete is a great way to ask for and gather reviews for your Google Business profile.
Check if the CRM allows for the logging and tracking of all communication records. This includes emails, calls, and text messages, to guarantee transparent and efficient communication management with customers.
If there’s ever a dispute, you’ll have access to time-stamped records that can help resolve any issues.
Double-check to see if the CRM has the capability to automatically synchronize live data. For example: fleet management software across multiple devices and platforms. All team members need to have access to updated and accurate information at all times.
This is useful for everyday jobs but will also come in handy during emergency situations, where you need to make sure every department is coordinated and customers are accounted for.
Confirm that the CRM offers seamless integration between mobile apps and desktop devices. Thus allowing you and your team members to access and manage operations from anywhere you’re at.
This enhances flexibility and helps HVAC technicians complete more jobs each day.
An HVAC Jobs and Sales CRM can significantly improve your business’s performance by integrating job management and sales functions with customer relationship management.
Combining these solutions can quickly streamline all aspects of your business. With tools like automated job scheduling and inventory management, your customers will notice the difference in service and praise you for its high quality.
Choosing the right HVAC CRM is a crucial decision. It directly affects the efficiency, customer experience, and long-term success of your business.
By asking the right questions and carefully evaluating how a solution like Commusoft supports your operational workflows and customer management needs, you can select an HVAC CRM that sets your business apart from the competition and drives sustainable growth.
Without the right technology in place, your business risks falling behind competitors who are equipped to manage every type of customer, residential or commercial, with speed and precision.
