Connection of the Air Conditioner and Furnace


The furnace and air conditioner have a connection to help operate efficiently. While there is no denying that cooling systems and central heating are two completely different things, they still work together in unison.

Central Heating Connection

As you would expect, every central heating system contains a primary appliance for heating, like a furnace. This is generally located in the garage or basement. Each furnace contains four critical components:

  • A blower
  • Heat exchangers
  • Burners for burning and delivering fuel
  • Flues to help exhaust gas byproducts

Depending on an individual’s need, region and situation, you can select heating systems that run on either oil or gas as fuel. You can also opt for hybrid packaged systems which are more than capable of utilizing both types of fuel.

How Does Central Heating Work

The burners present inside furnaces generate combustion gasses, passing them through heat exchangers. The heat present inside your home then blows the heat exchange to make sure it is warm. After then, the heat blows through ducts ensuring an even distribution of warm air around your house. When the weather is warmer, heating systems start working with the central air conditioning system.

The air becomes cool as it blows over the AC’s cooling coil. In most cases, this coil is connected to the furnace’s air circulating fan and sent through the air ducts in your home. If you are having trouble choosing the right central heating and cooling system, consider having a word with a professional HVAC expert, who can help you select a unit that suits your particular needs.

Central Cooling

Split systems are arguably the most popular central cooling systems. This includes indoor evaporator coils and a cabinet that contains the compressor and condenser oil, generally installed with the air handler or furnace. After that your cooling system’s compressor pumps through a chemical known as refrigerant throughout the system.

Connection for AC and Furnace

As soon as the warm air in your home starts blowing across the evaporator coil indoors, its energy starts transferring towards the coil’s refrigerant. This transfer results in the cool air generated by the unit. What’s more, the refrigerant then returns to the compressor, after which the cycle starts again.

The heat that the refrigerant absorbs moves outside the house as the cool air blows inside. The moisture that creates humidity also condenses out from the air. One of the biggest reasons why cooling systems and heating systems are combined is because their ductworks are quite similar (for dispensing conditioned air in your home.)

Whole-Home Humidification Systems and Benefits



These days, between quarantining and the temperatures dropping, we’re spending most of our time indoors. Have you ever stopped to think about the air you’re inhaling? When humidity levels are too high or too low, indoor air quality gets compromised. That’s why a whole-home humidification system might be a great solution for you. In this article, we’ll discuss the importance of maintaining proper humidity levels and how whole-home systems can help you achieve this.

What happens if humidity levels are too low?

Ideally, indoor humidity levels should be somewhere in the range of 30 percent to 50 percent. When winter’s cold, dry air comes into contact with heated indoor air, it can lead to dehumidification. This can lead to many problems with your health and your home. If your air isn’t humid enough, you may experience the following symptoms. This includes nose bleeds, dry or itchy skin, sore throat, dry eyes, or asthma flare-ups. It may also include increased allergy attacks. Additionally, your house could experience the negative effects of low humidity levels. These include excessive dust, indoor pathogens, static electricity, cracked wood, and bacteria.

What if your humidity levels are too high?

On the opposite end of the spectrum is high humidity. This occurs most often in the summer since the air naturally gets more humid. However, this can lead to a series of problems for homeowners. Below are some warning signs of high humidity in your home. This can be mildew and mold issues, pipes or ductwork sweating. There can also be condensation around the HVAC system. Check for any moisture near doors or windows. Make sure to have the humidity levels measured. This will help you determine if a whole-home humidification system is right for you.

How do whole-home humidification systems work?

Whole-home humidification systems automatically detect your home’s humidity levels. They maintain ideal humidity levels by increasing or decreasing moisture in the air. They do this by using water that’s already in your plumbing system.

There are two different types of whole-home humidifiers: power humidifiers and bypass humidifiers. Power humidifiers have built-in blowers, so they run even when your HVAC unit isn’t on. Power humidifiers are usually recommended for larger homes. On the other hand, bypass humidifiers attach to the furnace’s ductwork. When the blower turns on, water droplets are added to the circulated air. If you’re not sure which option is best for your home, our knowledgeable technicians are happy to discuss your options.

Benefits of a whole-home humidification system

Compared to portable humidifiers, whole-home humidification systems have the following benefits:

Safety​: Since whole-house systems don’t require excess water, there’s no chance of bacteria and mold accumulation.

Efficiency​: Whole-house systems use water from your plumbing system. That means they’re automatically refilled and cheaper to operate.

Low maintenance​: Compared to portable models, whole-home systems require little maintenance. The only thing to keep in mind is that your water panel needs to be changed out once a year. As long as you have your HVAC maintenance regularly scheduled, you shouldn’t need to do anything else.

You deserve clean air that feels comfortable all year. Are you interested in learning more about whole-home humidification solutions? Our licensed technicians at Ron’s Mechanical are here to help. Give us a call today at ​(952) 445-8585.

How Ductless Mini Splits Can Help with Heating and Cooling in Your Home

Do you have a space in your home that always feels too hot or too cold? If the answer is yes, then you need to know about ductless mini splits. These systems offer a quiet and efficient way to control the temperature in your home. In this article, we’re going to talk about what a ductless mini split is, and go over some of the pros and cons. We hope this will help you decide if this is the right option for you.

What’s ductless mini splits?

A ductless mini split is a compact heating and cooling unit. As its name implies, it’s designed as a split system that requires no air ducts. The system has one indoor and one outdoor unit, and is smaller than traditional HVAC systems. Unlike a traditional system, each unit of a ductless mini split system services an individual room or area, not the entire home. Each unit uses a separate evaporator coil and fan. Their flexibility has made them a popular heating and cooling solution for many homes. They’re very efficient at controlling temperatures in hard-to-reach areas. What’s great about them is that they can be used by themselves, or they can supplement your current HVAC system. Since they’re ductless, they’re easy to install and can work for almost any area in your home. They’re often used in finished basements, garages, and attics.

How does ductless mini splits work?

All ductless mini splits offer cooling, and some models provide heating as well. These systems run off electrical power, working exactly like a heat pump. Their technology enables them to collect heat from the outdoors (yes, even in cold winter months), and move it into your home. A mini split system can have many indoor units. With each unit working separately in different indoor spaces, you have more control over the temperature of each area.

What are the benefits?

There are several important benefits to ductless mini splits. The first is that they’re extremely efficient systems, meaning they can run with very little energy. They also use variable-speed compressors. This means they can run as little or as much as you need. Since they don’t have a binary on / off switch, they’ll save you energy. Another benefit is the level of control they give you over your home’s temperature. Since these systems have many units, one can be running while the other is switched off. What’s more, one unit could be cooling a room, and another unit could be heating a different space. Having this level of control lets you customize your living spaces exactly how you want them.

Are there any downsides?

With most things, there are downsides to consider. One downside of a ductless system is that their air filters aren’t as powerful. This means they’ll be less effective at filtering your home’s air. These filters should be cleaned out every few weeks, especially if you plan on using your ductless mini split system all year. Another factor to consider is their appearance. Ductless mini split systems run a line from the outdoor to the indoor unit. Since these units are often in strange spots in your house, you could have a line running down your home or around its corners. This doesn’t always look the most visually appealing. A solution for this is a line hide. A line hide is a covering that’s used to blend the line into the exterior of your home.

If you’re looking for heating and cooling solutions for your home, then you need to consider ductless mini splits. Do you have questions about these, or anything HVAC-related? Our skilled technicians have answers. Give us a call today at ​(952) 445-8585.

How a Whole House UV Filtration System Improves Air Quality

Scientists have known that UV light can stop the growth of microorganisms and bacteria for over 100years. As a result, UV lights are used for sanitation purposes in the food industry, hospitals, and water filtration systems. Did you know that ultra violet lights can also purify the air we breathe? Today we’re discussing how ultra violet lights work in home HVAC systems to improve the quality of indoor air. Keep reading to find out more.

How do UV lights help improve air quality?

  1. In residential HVAC systems, most of the air used gets recirculated. This air can carry all sorts of pollutants, which we breathe in. UV lights work to remove the following from indoor air:
  2. Germs
  3. Pathogens and viruses
  4. Dust
  5. Bacteria
  6. Allergens
  7. Fungi or mold

Anyone can benefit from the installation of ultra violet lights in their home HVAC system. It’s an especially good idea for people with allergies, pets, or children. Additionally, if you live in a humid area that’s susceptible to mold growth, you’ll want ultra violet lights to remove those invisible particles from your air.

How it works

UV light cleans the air by trapping and eradicating pollutants. The DNA of these pollutants break down when they come into contact with the ultraviolet wavelength. As a result, they can’t reproduce and they gradually die off. When air travels through the chamber with ultra violet light bulbs, it gets purified.

Types of UV light for residential HVAC systems

You have two options when selecting UV lights for your home HVAC system: Coil Sterilization and Air Sterilization. Let’s examine both of these.

In Coil Sterilization, a UV light is positioned in your HVAC system’s return air duct. This stick-shaped light cleanses the air handler coil. Coil Sterilization systems run 24/7.

Your other option is an Air Sterilization system. Like Coil Sterilization, this system has a UV light installed in your HVAC system’s return air duct. Instead of a stick light, this option is a complete UV light. This light cycles on with the air handler blower, and it works to purify moving air.

Of these options, Coil Sterilization is the most popular UV light for residential HVAC systems. It also happens to be the most reasonably priced of the two.


Placement is the most important factor in how effective your ultra violet light is. For optimal use, the UV light should be mounted next to the evaporator or cooling coil. They need to be on the cold air side, which is the downstream side of the coil.

Your ultra violet lights need to illuminate the water drain pan underneath the coil, as well as the cooling coil itself. Since there’s water here, there’s always a possibility for mold growth. By positioning the UV lights in these parts, it purifies your air by destroying these pollutants.

Mounting your ultra violet lights elsewhere opens your system up for bacteria and mold to spread. This results in contaminated air, which no one wants in their home.


UV lights in home HVAC systems are effective at purifying indoor air, as long as they’re positioned correctly. They can help stop the spread of viruses, colds, and other bacteria. Given our current COVID-19 concerns, air purification systems are definitely worth considering these days.

Installing a Garage Heater and Transform Your Space


No matter what climate you live in, a heated garage is a must. It’s a great project for any homeowner because it can transform your space into a functioning bonus room. Whether you want the extra space for a workout room, a workshop, or the ultimate man-cave, installing a garage heater is your first step to getting there.

There are lots of options to fit any space. While a portable heater can be useful, installing a permanent heater is a much better idea. This is especially true if you are looking for a long-term solution for a large space. There are two main types of heaters to choose between: gas garage heaters and infrared garage heaters. Let’s take a closer look at each of these.

Gas garage heaters

To install a gas garage heater, you need to be able to hook up a gas line. You’ll also need to make sure it can vent. Gas garage heaters are built to hang from ceiling joists. Once your heater is securely mounted to the ceiling, you’ll need to set up the ventilation. To do this, cut a small hole in the roof. From here, you can install flashing and insert the vent pipe. This flue allows you to vent any fumes out of your garage. Once this is done, you can waterproof your system with sealant, a weather ring, and a vent cap.

If the heater has an electric thermostat or circulation fan, you’ll also need electricity. Your heater should come with a guide that will help you with this part. Keep in mind you’ll also need to run gas lines to your garage for your heater to work. Installing a garage heater is no small job. Unless you feel confident with electricity and gas, it’s not a bad idea to seek help from a professional.

Infrared garage heaters

An electric infrared heater can be mounted to the wall or ceiling of your garage. They typically need to be about six or seven feet away from the floor. Your heater’s installation guide will provide specific safety information for installation.

As long as you have the correct plug-ins, you should be able to plug in a small heater and be good to go. If you’re hard-wiring your system, you’re going to need some extra help. Since this will require installing a new circuit breaker and new cables, you’ll probably need an electrician for this step.

Which type of heater is better?

Infrared heaters are more cost-effective than their gas counterparts. Since the heat radiates downward, the infrared heater produces radiant heat. Like the sun, it works by warming people and objects in the room. A gas heater works by warming the air. Generally, a gas heater will warm up the air faster than an infrared heater. However, it’s more costly to run. For that reason, we recommend infrared heaters.

What You Should Know If You Need a New Furnace This Year

If your furnace often needs repairs, or if you’ve had it for several years, it may be time to buy a new one. In this article, we’ll talk about red flags that indicate you need to replace your furnace. We’ll also discuss how the HVAC industry has been affected by the COVID-19 pandemic. Let’s dig in.

5 warning signs that your furnace may be failing

If your furnace is on its way out, it’ll definitely let you know. There are several warning signs that indicate you need to replace your system. These include the following:

1. You’ve had lots of recent furnace repairs

When furnaces get old and their parts wear out, they need lots of repairs. When this happens, you end up pouring money into an HVAC system that’ll need replacement in a few years at most. At some point, it makes more sense financially to invest in a new system.

2. Your heating bill has increased

Over time, your furnace’s efficiency decreases. This is because its internal parts slowly wear down as your system ages. You should definitely schedule a maintenance appointment if you see a significant increase to your gas bill.

3. Your furnace is making strange noises

If you hear lots of rattling, banging, or popping coming from your furnace, it may be time for a replacement. Old furnaces are quite noisy, and this indicates that your system may be on its way out.

4. You always feel too hot or too cold

Are you constantly adjusting the thermostat because you feel too cold or too hot? If so, it could be because you don’t have proper heat distribution in your HVAC system. If you’re experiencing this, you’ll probably want to replace your furnace.

5. Your HVAC system is more than 15 years old

A typical furnace lasts around 18 years. If your furnace is 15 years or older, we recommend replacement. This is especially true if your system needs routine maintenance to function.

When should I get my furnace replaced with a new one?

The best time of year to replace your furnace is in the spring or fall. Here’s why:

1. Better value

Fall and spring are the best seasons for furnace sales and price cuts. Oftentimes, there are new models leftover from the year before. These systems are sometimes sold at discounted prices. You’re more likely to see price cuts during the off-season, when temperatures are mild.

2. Mild weather

In the spring and fall, you don’t typically need to run your home heating system. These milder seasons are the best times for furnace repair and replacement. A few days without heat is manageable this time of year.

3. Better appointment availability

Our busiest season is during the winter months. This is when the most heating emergencies happen. Scheduling maintenance and repairs is much easier in the fall and spring. Since we have more availability, we can be flexible to accommodate your schedule.

Get your furnace replaced now, before it’s too late! COVID-19 has impacted a lot of businesses this year, including furnace plants. Since many of these plants have been shut down, supply chains were interrupted. That means there aren’t as many furnace units being manufactured this year.

The last thing you want to do is delay service during a furnace shortage. Don’t wait. Give Ron’s Mechanical a call today to schedule your appointment. You can reach us at ​(952) 445-8585. ​We look forward to seeing you soon.

Why Every Homeowner Should Consider Upgrading to a Smart Thermostat

smart thermostat

In today’s modern age, just about anything can be operated through our phones and computers. The latest craze in homeowner tech is smart thermostats. Today we’re going to talk about how smart thermostats work, and why it’s a good idea to invest in one. We’ll also talk about why it’s best to get your new system professionally installed.

How does a smart thermostat work?

A smart thermostat uses a wifi connection so you can control your home’s thermostat settings on an electronic device. This means that you can change your thermostat remotely. If you’re someone who travels in the winter for the holidays, you need a smart thermostat. Having your heating system malfunction or die while you’re gone is the last thing you want. It could cause frozen pipes, which could lead to thousands of dollars in damages. Since a smart thermostat monitors your HVAC system, it could prevent this catastrophe.

There’s a variety of smart thermostats out there that come with lots of different features. Some of them track your heating and cooling habits to record your yearly energy usage. Others adjust temperatures automatically based on time of day or learned preferences. Higher-end models can even alert you to possible issues with your HVAC system. Others can make sure your house is at the perfect temperature when you get home by tracking when you leave work. As you can see, smart thermostats offer a lot more than standard thermostats.

How much do they cost?

Most smart thermostats cost somewhere in the neighborhood of $100 to $300. All things considered, that’s not too expensive. Although pricier models come with more advanced features, even the most affordable smart thermostat is a huge upgrade.

Is a smart thermostat worth it?

We recommend smart thermostats because they save you money on energy bills. Using one saves about 10 to 12 percent on heating bills, and about 15 percent on cooling. This adds up to an annual savings of $130 to $145. That means your smart thermostat pays for itself within a year or two of purchase and installation. The smart thermostat lifespan is around 10 years, which means it can save you well over $1,000 in energy expenses.

Benefits of professional installation

It’s always a good idea to hire a professional to install your smart thermostat. Here’s why. Most smart thermostats need a c-wire. Although a lot of newer homes are equipped with these, many old houses don’t have them. If you don’t know a lot about your electrical system, installing a smart thermostat can create a lot of problems for your HVAC system. Some of the most common problems we’ve come across are strange noises, HVAC systems powering on and off without warning, constant running, and delayed starts. If you leave installation to a professional, you won’t have to worry about any of these complications. Additionally, you’ll have someone on-hand to help you learn all about your new gadget.
