Initial Consultation and Free Quote
We start by getting to know you, your home, and your heating and cooling system. Our team asks questions to understand your thermostat needs, budget, and preferences. Then we provide a free quote with upfront pricing. No guesswork, no surprises.
Recommending the Right Thermostat
Not every thermostat fits every HVAC system. We evaluate your setup and recommend the best thermostat options—whether that’s a smart thermostat, programmable model, or a simple replacement. We walk you through the pros and cons of each to make sure you’re confident in your choice.
Professional Installation by Trained Technicians

Testing and System Walkthrough
Once installed, we test the thermostat and the full heating and cooling system. We check for proper communication with your furnace, heat pump, or air conditioner, and ensure the desired temperature is achieved quickly and efficiently. Then we guide you through the new system so you know exactly how to use it.
Clean-Up and Follow-Up
After installation, we clean up the workspace and leave your home just as we found it. We follow up to make sure you’re happy and that the system is running just right. And if you ever need us again, we’re just a phone call away.
Let All Pro handle your thermostat installation for minimal disruption, maximum comfort, and reliable service every step of the way.
Thermostats We Install in Ontario, CA
Thermostats aren’t one-size-fits-all. Every home is unique, and so are your heating or cooling system needs. That’s why we offer a wide range of thermostat options to fit your system and lifestyle.
Smart Thermostats
Smart thermostats are the future of energy efficiency and home comfort. These intelligent devices learn your habits and automatically adjust to your schedule. Many models are Wi-Fi enabled, so you can control your thermostat from your phone, tablet, or voice assistant.
Features like geofencing, usage reports, and adaptive learning help you save on energy costs while keeping your home at the perfect temperature. We install popular brands and will help you connect your thermostat to your existing HVAC system and home network.
Zoned System Compatible Thermostats
Have multiple floors or rooms with different comfort needs? A zoned system thermostat gives you precise control over each area. Whether you’re using ductless mini-splits or a zoned air handler system, these thermostats keep everyone happy without wasting energy.
Programmable Thermostats
Want to set it and forget it? Programmable thermostats are a great choice for those who like a predictable schedule. You can pre-set different temperatures for morning, day, evening, and night. They’re especially handy for saving money while you’re asleep or away from home.
Non-Programmable Thermostats
Sometimes, simple is best. If you just need to manually adjust the temperature, a non-programmable thermostat is budget-friendly and easy to use. It’s a solid option for rental units or folks who prefer minimal tech.
Mechanical Thermostats
These old-school thermostats still do the trick in many homes. While not as precise or efficient as modern models, they’re reliable, familiar, and inexpensive to replace or repair.
We help our customers choose the right thermostat to match their comfort goals, budget, and HVAC setup. And of course, every installation comes with the All Pro promise of satisfaction.
How Much Does a Thermostat Installation Cost in Ontario, CA?
Thermostat installation costs vary depending on the type of unit, the complexity of the installation, and whether you’re upgrading to a smart system. On average, Ontario homeowners can expect to pay anywhere from $100 to $500 for a professional thermostat installation.
At All Pro, we believe in transparency. That’s why we offer upfront pricing and free quotes. Whether you’re replacing a simple dial thermostat or installing a top-tier smart model, we make sure you understand the cost before we start. No hidden fees. No surprises. Just quality work, done right the first time.
Thermostat Repair Services in Ontario, CA
Even the best thermostats can run into trouble. When your system starts acting up, All Pro is here with fast, friendly thermostat service to get your heating or cooling back on track.
Common Thermostat Issues We Fix
Even the most reliable thermostats can encounter problems from time to time. When your system starts acting up, it’s not just annoying—it can also mess with your comfort and even increase your energy bills. Luckily, our expert technicians have seen it all and know exactly how to get things running smoothly again. Here are some of the most common thermostat issues we tackle every day:
No Power or Display
A blank screen could mean a wiring issue, dead batteries, or internal failure. We get to the root of the problem fast. Sometimes it’s as simple as replacing batteries or flipping a tripped breaker. Other times, we may need to dig deeper into electrical components or replace the unit entirely.
Inaccurate Temperature Readings
If your thermostat isn’t sensing the temperature correctly, your HVAC system might short-cycle or run non-stop. We’ll recalibrate or replace the unit. Poor placement near windows, doors, or vents can also throw off readings. We make sure your thermostat is in the best location to measure true indoor conditions.
Short Cycling or Constant Running
This could be a sign of poor placement, faulty wiring, or a bad sensor. Our technicians know how to fix it without guesswork. We also look into system compatibility, as an outdated thermostat might not sync properly with newer HVAC components.
Connectivity Issues with Smart Thermostats
Lost Wi-Fi connection? App not syncing? We troubleshoot and restore your thermostat’s smart features quickly. We also help ensure your router and smart device settings are properly configured for seamless operation.
Failure to Activate Heating or Cooling
If your furnace, tankless water heater, or air conditioner won’t turn on, the thermostat could be the culprit. We test connections and restore full functionality. In some cases, a blown fuse or malfunctioning relay may be involved—we’ll handle that, too.
Thermostat Doesn’t Hold Settings
Constantly resetting your thermostat is frustrating. We check for software glitches, power issues, and compatibility problems. If needed, we will update firmware or recommend a more stable model that works reliably with your system.
Our thermostat repair services are fast, professional, and designed to get your comfort system back online with minimal disruption to your routine.

Wired vs. Wireless Thermostats – Pros and Cons
Choosing between a wired and a wireless thermostat depends on your home’s infrastructure, your personal preferences, and how much control and flexibility you want over your HVAC system. Let’s take a closer look at both options to help you make the best decision for your comfort and convenience.
Wired Thermostats
Wired thermostats have been around for decades and are known for their reliability and consistency. They connect directly to your HVAC system via low-voltage wiring, which means fewer interruptions and a strong, stable signal.
Pros:
- No need for batteries or recharging
- Fewer connectivity issues
- Consistent power supply
- Ideal for permanent installations
- Often more affordable
Cons:
- Requires existing wiring or professional installation
- Limited placement due to fixed wiring locations
- Not as easily upgraded to smart features without additional wiring work
Wired thermostats are a solid, long-term choice for homeowners who want a stable, no-fuss connection. They’re especially great in homes with existing wiring or when you’re doing a major renovation.
Wireless Thermostats
Wireless thermostats are the modern solution for homes without traditional thermostat wiring or for those who want more flexibility. Most wireless models are smart thermostats, meaning they offer mobile app control, learning features, and remote access.
Pros:
- Easy and flexible installation
- Can be placed or moved almost anywhere
- Smart features like remote control, scheduling, and usage tracking
- Great for renters or temporary setups
- Modern design with intuitive interfaces
Cons:
- Requires batteries or regular charging
- Dependent on strong Wi-Fi signal
- More expensive upfront cost
- Occasional connectivity or syncing issues
Wireless thermostats offer modern convenience and tech-savvy features, making them perfect for homeowners who love smart home integration and want ultimate control from anywhere.
Both options have their place, and at All Pro, we’ll help you weigh the pros and cons based on your home setup and lifestyle. Whether you choose wired or wireless, we make sure your thermostat installation is smooth, professional, and perfectly suited to your needs.
Smart vs. Traditional Thermostats – Pros and Cons
When deciding between smart and traditional thermostats, it really comes down to your lifestyle, comfort preferences, and how hands-on you want to be with your HVAC system. Both have their strengths, and the right choice depends on what matters most to you: simplicity or smart features.
Smart Thermostats
These tech-savvy devices do more than just control your home’s temperature. Smart thermostats learn your habits, help reduce energy waste, and offer remote access through smartphones and other devices.
Pros:
- Learns your schedule and adjusts automatically
- Remote access via mobile apps, tablets, or smart speakers
- Provides energy usage reports and efficiency insights
- Sends maintenance reminders (like when to change air filters)
- Integrates easily with smart home systems and voice assistants
Cons:
- Higher upfront cost
- Requires Wi-Fi and potentially a compatible HVAC system
- Setup can be complex without professional help
- Some users may find the tech overwhelming or unnecessary
Smart thermostats are great for homeowners who want more control, love automation, or are looking to save on long-term energy costs. They’re also ideal for frequent travelers or people with irregular schedules.
Traditional Thermostats
Traditional thermostats do the job with minimal fuss. They offer basic temperature control with manual adjustments and little to no digital interface.
Pros:
- Budget-friendly and widely available
- Simple to use with basic up/down temperature controls
- No Wi-Fi or app required
- Less prone to software bugs or connection issues
Cons:
- No remote control or automation
- Doesn’t adapt to your schedule
- Can lead to higher energy usage without precise programming
- Lacks insights into system performance or maintenance
Traditional thermostats are a great fit for those who prefer simplicity or don’t want to deal with learning new technology. They offer solid performance without the bells and whistles.
Choosing between smart and traditional thermostats comes down to how involved you want to be in managing your home’s heating and cooling. Whether you prefer the advanced control of a smart system or the ease of a traditional model, All Pro is here to guide you through every step of the decision-making and installation process.
Smart Thermostats vs Zoned Climate Control Systems
Smart thermostats and zoned climate control systems both offer powerful ways to manage your home’s comfort, but they work in slightly different ways. A smart thermostat is typically designed to control the overall temperature of your home through one centralized device. It learns your routines, adjusts automatically to your schedule, and lets you control settings remotely through an app. This can lead to noticeable energy savings and added convenience, especially if you’re someone who likes automation or travels often.
Zoned climate control systems, on the other hand, divide your home into separate areas or “zones” that can be controlled independently. This means you can keep your bedroom cool at night without wasting energy cooling the entire house. It’s ideal for larger homes or households with different temperature preferences. Zoned systems use multiple thermostats, sensors, and sometimes even motorized dampers within your ductwork to regulate airflow and temperature in each zone.
The good news? You don’t have to choose between the two. Many smart thermostats can be integrated into zoned HVAC systems, giving you the flexibility of smart control with the precision of zoned climate management. At All Pro, we specialize in designing and installing customized systems that give you total control, energy efficiency, and year-round comfort.
Do Smart Thermostats Help With Energy Efficiency?
Absolutely. Smart thermostats can reduce energy usage by learning your schedule, adjusting when you’re away, and giving you insights into your HVAC system’s performance.
They prevent unnecessary heating or cooling, which lowers your utility bills and reduces wear and tear on your system. Over time, many homeowners see real savings from these intelligent devices.
