Top 5 Benefits of Having an Electrical Inspection on Your Old Boston Home

One of the most important systems in any home is its electrical system. It’s responsible for providing power to every room in your house and is the cornerstone of your home’s functionality. Electrical wiring runs through each of your walls, the floors, and the ceiling to provide electricity to overhead lights, wall outlets, appliances, and more. Any interruption in this system can be inconvenient at best and may completely destroy your electrical wiring at worst.

5 DIY HVAC Repairs Gone Wrong

Many homeowners look for ways to save money on their household expenses, especially when it comes to big ticket items like the installation, repair, and maintenance of an HVAC system. Sometimes, homeowners are tempted to do the work themselves, assuming that it’s easy enough with the help of an instructional YouTube video and parts purchased online or at a hardware store.

How to Improve Office Ventilation in the Winter

Indoor air quality is an important consideration in work productivity and efficiency. Poor air quality can slow office workers down, making them feel sick, tired, or unable to think clearly. Ventilation is hard to come by during the winter, when office windows and doors are closed to protect employees from the frigid Massachusetts air.

Here’s what employers should know about toxic office air in the winter and they can do about it.

Ductless Deep Cleaning for Spring

Your HVAC system is a significant contributor to the quality of your air, especially in spring when the number of allergens in the air is much higher.

The Boston Globe reports that allergy season in Massachusetts is typically between May and August, and the Asthma and Allergy Foundation of America lists Springfield, Massachusetts as one of the top 10 worst cities in America for allergy sufferers.

This means that keeping your ductless AC clean is an important part of ensuring your air is healthy and your air conditioning works properly, but it’s something a lot of people don’t prioritize. With COVID-19 now a part of daily life, making sure your respiratory health is in peak shape is also high on the list this summer.

Unfortunately, self-cleaning HVAC technology doesn’t yet exist and chances are, you’re not getting the clean you need from simply maintaining your filters. A professional deep cleaning removes far more waste from your system and keeps it running smoothly throughout the season.

Here’s how we deep clean your ductless unit for spring or any other time of the year:

Install a Splash Guard

Before cleaning your ductless heat pump, we put up a protective splash guard called a bib to prevent dirt, debris, cleaners, and water from splashing onto your walls or floor. This mixture contains harmful particulates like fungi and bacteria, according to Time Magazine. We collect this dirty water in a receptacle that can be easily washed down the drain.  

Apply Advanced Formulated Foaming Cleaner to the Unit’s Coils

Next, we disassemble your unit and apply a high-tech foaming cleaner to the coils. The cleaner is formulated to begin breaking down oil and dirt immediately and only requires a short amount of time to start working.

AerisGuard Ductless HVAC Cleaner Logo

The Hydrokleen system uses AerisGuard cleaners that have been specifically designed to clean and protect ductless HVAC systems. These non-toxic, multi-enzyme cleaners are made to break down organic waste and detach it from the coil’s surface so it can be easily sprayed away. Without these formulas, it is much more difficult to remove hard, caked-on debris, even with aggressive scrubbing.

Pressure Wash the Unit

Once the AerisGuard foaming cleaner has been working for a few minutes, our experienced HVAC technicians will begin to pressure wash the unit’s coils. This physically flushes water through the system to remove mold, mildew, dust, bacteria, and virus particles that may be hiding deep within.

This type of cleaning can’t be achieved by simply removing and rinsing your ductless filters; it requires professional service from a trained technician. It is recommended that you clean the filters yourself every four to six weeks and have a deep cleaning done at least annually if not seasonally before spring and again in the fall.

Clean the Chassis, Barrel Fan, and Other Components

Next, other parts of your ductless air conditioner will be cleaned, including the chassis, the barrel fan, the louvres, the drain pain, and all other components.

Often, dirt and debris will build up on the back of the fan, giving the illusion that the system is cleaner than it is. Meanwhile, the dirty fan contaminates all of the air that passes through it and into your home. It also reduces the overall air velocity, causing the unit to become inefficient at cooling and increasing your energy bills. Energy.gov reports that your air conditioner can become 5% to 15% less effective at cooling your home if the filters are clogged.

The Hydrokleen system allows us to quickly and easily clean these parts that you may not be able to reach on your own. A deep cleaning not only improves your air quality but also helps you save money on your electric costs by significantly reducing the workload on your unit.

Apply a Protective Coating to the Coils

After the HVAC system has been cleaned, we apply a specially formulated AerisGuard protectant to your air conditioner’s components to create a biostatic layer that discourages the buildup of debris on the unit’s coils. This helps to improve air quality and control odors, because waste that would ordinarily build up and cause a musty, mildewy smell is no longer able to do so.

AerisGuard products are non-acidic, helping to protect the longevity of your system over time. Other cleaners that contain harsh corrosives can damage the coils and other ductless system components, requiring you to replace or repair them sooner.

Reassemble the Ductless Unit

After our technicians have serviced your unit, it will be reassembled and tested to ensure that it is working properly for both heating and cooling. Our HVAC techs don’t leave your home until we know that everything is in order and you won’t have any difficulty starting your system back up after the deep clean.   

Check the Outside Compressor

We’ll also check the outdoor compressor of your unit to ensure that there is no vegetation growing over it. We’ll look for signs of damage and make sure that there isn’t any ice buildup that could be impacting your HVAC system’s ability to cool your home. Whether you have a single outdoor unit or a multi-zoned system, our technicians are capable of providing you with expert service.

Ductless Allergen Filtration

Mitsubishi Electric Cooling & Heating systems use a sophisticated multi-stage filtration system to help remove airborne particles and contaminants such as allergens, viruses, and bacteria from the air as they circulate within a room.


DUCTLESS INDOOR AIR QUALITY

It’s a fact that surprises many people. The air quality inside your home is often worse than the air quality outside. Mitsubishi Electric Cooling & Heating systems use a sophisticated multi-stage filtration system to help remove airborne particles and contaminants such as allergens, viruses, and bacteria from the air as they circulate within a room.

The large hybrid catechin pre-filter absorbs odor-causing gases. A blue-enzyme, anti-allergen filter helps reduce germs, bacteria, and viruses and helps trap dust, pollens, mites, and other particles that plague allergy sufferers. Some systems also include a Platinum Catalyst deodorizing filter to further reduce unpleasant odors. As a result you enjoy pristine air 24/7.


SUPER-EASY MAINTENANCE

Although the filtration system is sophisticated, it’s easy to clean and maintain.  You can perform this task in a matter of minutes. Simply open the indoor unit’s filter access; slide the screens out; wash them off; allow them to dry completely, and then slide them back into the unit. With regular cleaning, the hybrid catechin filters can last up to 10 years. This capability not only saves money, but is also good for the environment. 

AND MORE:

  • Removes particulates and contaminants from the air with continuous fan operation for better air circulation
  • Easy-to-clean hybrid catechin pre-filters absorb odors and last up to 10 years
  • Anti-allergen filter traps dust, allergens and other particles to improve indoor air quality (IAQ)
  • Platinum Deodorizing filter (select systems) uses nanotechnology for highly effective odor absorption

What an LG Ductless Mini-Split System Costs Around Boston, MA

Here in the Greater Boston area, ductless heating and cooling in a single zone configuration, fully installed and ready to turn on starts at $4,500 and the price goes up from there depending on a number of factors.

Buyer Beware

You may have found websites that claim it costs $1867 to purchase a new ductless mini split, and $159 to have it professionally installed. As you can imagine, that price is not only the cheapest, least efficient unit on the market, but I don’t know a contractor worth allowing into your home who would charge that little for labor. Proceed with caution.

Ductless Mini-Splits are Whisper-Quiet

By now you may already know that ductless is a quiet, efficient heating and air conditioning solution for your home that will reduce your energy costs and in some cases, pay for itself in energy savings.

But, what can a homeowner expect to pay for this modern, convenient heating and air conditioning solution in the greater Boston area?

Ductless mini-split technology has been around for more than 50 years, but has only been available to New England homeowners for about thirty years.

In Japan, ductless accounts for 90% of all HVAC systems sold, and more than 80% in Europe.

Unfamiliarity with ductless technology and spotty access to educational information has slowed the growth of ductless acceptance in the United States, but the efficiency of ductless has caused major utility companies, government agencies and homeowners to take notice.

The financial incentives associated with ductless technology have made it one of the fastest growing home comfort solutions for residential heat pump and residential air conditioning replacements.

So, how much can you expect to pay to have a Mitsubishi ductless system installed in your home? Of course I’m going to tell you, it depends.

The price of a ductless system is determined by four primary factors:

  • The size of the unit
  • The type of unit
  • The number of areas (or zones) being conditioned
  • The degree of difficulty of the installation (How far the indoor and outdoor units are from each other, the construction of the outer wall to be drilled to carry the line sets, etc.)

Due to the flexibility of these systems (whole house, partial house, one room, etc.) there are multiple design possibilities that can slide your job from the lower end of the cost range to the highest. A ductless system, on its most basic level, consists of:

LG DUCTLESS INDOOR

LG DUCTLESS OUTDOOR

AND, LINE SETS TO CONNECT EVERYTHING

Single Zone Mitsubishi Ductless Installation

Professional installation of the most basic, or single zone, configuration (consisting of one wall unit and condenser) will cost between $3,500 up to $4,500. This layout is ideal for many kinds of applications like conditioning the air in a sunroom, garage, attic, and some smaller homes.

A single ductless unit is perfect for keeping a sun room comfortable all year long

Multi-Zone Mitsubishi Ductless Installation

Some New England homeowners need only one ductless unit, while other applications are better served by 3, 4 or 5 units. It all depends on the layout of the home and what works best for you.

A multi-zone system consisting of two indoor evaporator units typically run between $8500 and $10,000.

We can run as many as five indoor units with a single outdoor condenser, and we can come back to add indoor units at a later date if you want to have your system designed for future expansion as budgets allow.

A 5-zone system could cost $20,000 to $28,000.

Is ductless a good value for my money?

At first glance, the cost of ductless heating and air conditioning can seem steep, however, the benefits in energy efficiency will save you a lot in the long run.

Since there are no ducts, you don’t waste energy through leaky ductwork.

Typical forced air systems experience duct losses equivalent to about 20% of the system’s energy consumption. Often it’s over 30%.

Ductless systems are also less expensive to maintain than traditional systems.

When you add in attractive rebate programs and 0% payment plans, ductless solutions wind up shaking out as a net cost savings to most homeowners.

A multi-zone configuration comes with an additional energy saving benefit. You can control the temperature independently in every room where an air handler is installed.

So, if you’re not using a room, you won’t have to keep it heated and cooled the same as the rest of the house.

Finally, you’ll need a qualified installer, like NETR, Inc., and, as I mentioned earlier, there are some good reasons for that (beyond the fact that it’s us. :-))
