Thermostat technology has come a long way, and many homeowners are enjoying the convenience of smart thermostats. Here are just a few of the several reasons why you should contact Universal Heating & Air to discuss every advantage that comes with having a smart thermostat professionally installed by one of our outstanding representatives:
Want to install a top-of-the-line model in your house but aren’t sure which model or manufacturer is right for you? Don’t worry because, at Universal Heating & Air, we can help you make an informed decision. Here are a few of the best options in smart technology that will help you control your air conditioning system with ease:
Nest Thermostat
Manufactured by Nest Lab, the Nest Thermostat has several advantages over other smart thermostats. The Nest is easy to install and operate, and some models are equipped with another cool feature: Voice-enabled technology. This means that you can control your Nest Thermostat with your AI assistant, including Amazon Alexa. Nest is an excellent option if you want a sleek model that is also energy-efficient.
Ecobee Thermostat
Do you want a Wi-Fi-enabled thermostat that is sleek and elegant but can still get the job done? Ecobee thermostats will look fantastic in any space and are equipped with several unrivaled features, including a portable temperature sensor and motion sensor technology.
Honeywell Thermostat
A top name in HVAC technology, we install a large number of Honeywell thermostats throughout the Long Beach and Los Angeles areas, and for a good reason. Installing a Honeywell Thermostat can save you money, and various options are available, including more cost-effective nonprogrammable models. Honeywell offers several energy-efficient models that will fit any price range. Whether you are heating or cooling your Los Angeles home, you can find a Honeywell model that will provide you with all the services you could ever need.
Venstar Thermostat
Do you want your current model replaced with an easy-to-operate thermostat that can save you money? Venstar is a top name in the HVAC industry. There are several models to choose from, and a representative from our business can install the thermostat in a few minutes.
Yes, in many cases, thermostat repair is possible. However, if your thermostat is older and less energy-efficient, we might recommend other thermostat services, including upgrading your current model to smart technology.
You can install a new thermostat on your own. However, there is one central point that many homeowners overlook: thermostat calibration. Failure to properly calibrate your thermostat can cost you a lot of money simply because the temperature readout will not be accurate.
If you aren’t taking precautions and calibrating the thermostat, you could lose a lot of money.
Instead, choose the easy, convenient option and leave the installation of your thermostat to the team at Universal Heating & Air.
Not anyone can swap out a thermostat, especially if you are upgrading to a state-of-the-art smart thermostat. Smart technology can often be tricky, especially for beginners. Our team can handle the initial installation, program the thermostat, and help you understand the controls.
Allowing a professional to handle this job might mean a larger initial investment. However, the cost-saving potential of learning how to properly program and control your new thermostat. At Universal Heating & Air, teaching you how to properly control your air conditioning system is one of the many thermostat services we offer!
If your thermostat is malfunctioning, and you aren’t familiar with thermostat repair or replacement, your first instinct might be to swap out the current model instead of seeking professional service.
Before you head to your local house improvement or hardware store, realize several potential issues you can fix at home. For example, in many cases, your thermostat is not heating or cooling your home correctly simply because the batteries are dead.
If you swap out the batteries, but the thermostat still isn’t as hot or cold as you would want, pick up the phone and give us a call. We can troubleshoot your unit to determine if repairs or installing a new model is warranted.
Need a business that can expertly handle a new thermostat installation for your cooling system? Have several questions about smart technology? No matter what the issue, you can always contact the fantastic team at Universal.
With over 30 years of experience servicing and repairing the HVAC systems of Los Angeles-area homeowners, our company can provide you with convenient options for all your HVAC needs.
In addition to smart tech installation, you can contact us to service and fix your heat and cooling system. From a blown evaporator coil or air filter cleaning to a whole house replacement of your entire HVAC system, you can pick up the phone and call us to handle any problem.
We pride ourselves on keeping costs down without sacrificing quality and integrity. Universal Heating & Air is determined and in the business of saving you a huge amount of money while ensuring your space is as hot or cold as you want.
When hiring local HVAC installers, you must think about the following aspects first:
The experience of the HVAC installer will say a lot about his expertise. Always choose a provider that has been in the industry for years.
You should only hire a licensed contractor for air conditioning installation in Los Angeles. This ensures that the contractor has met industry standards to deliver HVAC services.
An HVAC installer with liability insurance values the safety of its employees and clients alike. This insurance coverage will protect you from obligations should accidents occur on the job site.
If this is your first time hiring an HVAC installer, you should perform a quick check on the Better Business Bureau website, Yelp, and Google Reviews. This will give you first-hand accounts of the company’s reputation.
