Earl's Heating & Air Conditioning

It's All a Matter of Pride

Maybe you’re wary of HVAC contractors because you have had some bad experiences in the past. But we want to change your mind. Earl's Heating & Air Conditioning is committed to providing excellent customer service experiences to customers in Merrillville, IN and the surrounding areas. We’ve got decades behind us as a company, and each of our HVAC technicians has years of experience as well. You can trust us to get the job done right, and to provide great service with any installation, repair, replacement, or maintenance service for your air conditioner, heater, or indoor air quality product. It’s all a matter of pride!

When to Call for Heating Service

We recommend that you call a technician for heating services the moment you notice something is wrong with your system. If your boiler is making a noise it never has before, give us a call. Reach out as soon as temperatures start to drop, or the temperature of the rooms in your home become uneven. It’s not worth it to wait for a complete system breakdown. Prevent the system from failing by scheduling service right when you notice a problem. Or schedule routine maintenance services with our heater experts to prevent repairs in the first place.

We Specialize in Residential Boilers

A boiler is a large system that you simply could not service confidently on your own without a certain level of experience. Just get in touch with our specialists when you need installation, repair, replacement, or maintenance. We’ve got all the experience necessary to diagnose problems quickly, provide quality repairs, or install a brand new boiler that is efficient and high–performance.

We Also Service Gas and Electric Furnaces

Boilers aren’t all we do here at Earl's Heating & Air Conditioning. We also install, repair, replace, and maintenance commercial and residential gas and electric furnaces. We can install your thermostat, repair a broken ignition system, replace an old heat exchanger or the entire system, fix your blower fan, or provide routine maintenance to prevent repairs. Call us today to schedule service for your furnace.

Your Air Conditioning Specialists in Merrillville

Our NATE–certified technicians are here for you as soon as you notice a problem with your AC system, including warm temperatures, poor efficiency, and short cycling. We are skilled at diagnosing problems quickly and communicating your options to you for repair or replacement. Central air conditioners need expert service in order for them to run smoothly, and we offer maintenance services that can help to do that as well. And with any installation or replacement, you can count on getting a system that runs efficiently and works as you need it for years to come. 

Choosing Central Air Conditioners

When it comes to selecting a new central air conditioner, we always recommend that homeowners go with the most efficient air conditioning systems they can. The more efficient the system, the less you spend every month, so look for the ENERGY STAR seal to see if you can save money and protect environmental resources with your installation. We have a number of options for you to choose from, including heat pumps and ductless systems on top of conventional split systems.

Some of Our Indoor Air Quality Options

We provide duct insulation and duct sealing services that can make your AC and heating systems run more smoothly and efficiently and keep temperatures balanced. We also have a number of installations to help keep you comfortable and healthy. This includes humidifiers, which add enough moisture to the air to alleviate dry skin and chapped lips, as well as air purifiers, air filtration systems, and air filters. We can install smoke detectors and carbon monoxide detectors too. Call to learn more about getting your indoor air quality under control in Merrillville.

Duct Insulation Matters

Duct insulation may not seem like such a big deal if you assume that your ductwork is in good condition. However, if you’ve ever had problems with uneven temperatures, hot and cold spots in the home, or poor energy efficiency, your duct insulation levels could be at fault. Call our team to add duct insulation so that your home can heat and cool more efficiently without so much heat loss through the ducts.

Humidifiers Help Your Household

Humidifiers are important for many homeowners when temperatures drop and the dry air takes its toll. If you’ve got a humidifier that works with your HVAC system to keep you comfortable, you may no longer struggle with dry, flaky skin or chapped lips and you may even get sick less frequently. Call us to get a whole–home humidifier that adds just the right amount of moisture back into the air.

Water Heaters Are for Year–Round Comfort

Your water heater isn’t just something you need for a single season. You need it to be working year–round for your comfort and cleanliness. Keep everything in the best condition possible with routine maintenance services, prompt repairs, and expert water heater installation from our team. We work with both tank and tankless water heaters and gas and electric models. Call our team to get the system that’s the right choice for your home or for services from experienced professionals in the Merrillville area.

Tankless Water Heaters: Are They Better?

Tankless water heaters are known for energy efficiency because they don’t have to store hot water throughout the day and night. Tankless water heaters are energy–saving devices that work well as long as they are properly installed. However, that doesn’t make a tank water heater a bad option. Tank water heaters still work well for many homeowners, and they may cost less to install. Call us to learn more.

Commercial HVAC Requirements

Commercial heating and AC systems have different requirements for installation, replacement, repair, and maintenance. It’s important that you find someone with the right level of experience to repair your commercial HVAC system, install a new one, put together a zoning system, install your thermostats, replace your blower fan, and more. We have the expertise and qualifications to work on systems 25 tons and under, so call us today to see what we can do for your commercial property in Merrillville.
