Hey, guys. It’s Pete with East Coast HVAC. Customers frequently ask us for DIY tips on how to get the most out of their cooling systems. Today, I’m going to give you three quick tips to make sure your cooling system is working properly and efficiently summer after summer.
Tip #1 
Turn your system on nice and early in the spring. By doing this, you’ll find out if there’s any issues well ahead of time and we can help you to resolve them. Turn your thermostat to cooling and turn the set point down. Within a few minutes, the outdoor unit should come on and you should have nice, cool air blowing from your vents. If neither of these things happen, you probably have an issue with your cooling system. By finding out nice and early, you leave plenty of time to resolve things before the real heat arrives. Don’t wait until it’s too late and you’ll save a bunch of money.
Tip #2
Check and change your air filter. If the system appears to be kicking on but isn’t quite cooling as much as you’d like it to, a lot of times, it’s as simple as a dirty air filter. Air filters are generally easy to replace, they’re inexpensive, and you can buy them at your local hardware store. For ductless systems, the same tip applies but the filter doesn’t need to be replaced. It just needs to be cleaned. Remove the air filter from the indoor heads and wash them out in the sink to let them dry and put them back in.
Tip #3
Make sure all of your supply and return vents are free and clear of obstructions. This may seem obvious but it happens all the time. Sometimes household items or a piece of furniture may have shifted covering up a return vent or a supply vent that’s critical for system performance. This reduces airflow and overall efficiency of the system so make sure that all of your vents are clear.
If you’ve tried these three tips and your system still isn’t performing, it’s time to call us! But remember, the sooner the better! Stay cool this summer!

Did you know having your HVAC ducts cleaned regularly is important to keep your HVAC system running efficiently and even keeps you breathing fresh air?
Unfortunately, there are professional duct cleaning myths that can make some people hesitant to have this important service done.

Conventional Systems vs. Mitsubishi Inverter Heat Pump Systems

In the HVAC industry, we are asked a plethora of difficult questions, such as:

  • Why did this part fail?
  • How much is this going to cost?
  • How much money will I save?
  • When will it pay itself back?
  • And, which system is best for my home?

With the complexity of HVAC systems, and the variability of the weather, design factors, home construction, and installation practices, every one of these questions is very challenging to answer!  Today, I’d like to examine the concept of Conventional Heating VS Mitsubishi Inverter Heat Pump systems, to discuss their practical uses and when each might fit better than the other.

The Basics
When speaking of conventional heating systems, I am generalizing what we call “Unitary” systems, consisting of gas or oil-fired furnaces and boilers.  In general, these systems are what most of you have in your home already.  You might have some duct work in your basement or attic, you might have a boiler and associated piping to baseboard heat or radiators, or you could also have a combination of the two.  In terms of the overall efficiency of these systems, think about it this way – The system burns some sort of fuel to generate heat, and there are several steps along the way where it can LOSE that heat and efficiency.  It starts right at the gas fired heat exchanger, which generally only transfers between 80% – 95% of the fuel consumption to real British Thermal Units (BTUs).  From there your system experiences loss in your duct work via air leaks in the ducts (dumping “lost” air into either your attic or basement), loss in the copper heat piping that runs throughout the basement or in the walls, or loss as a combination of those two things in a hydro-air system.  This inefficiency has been incrementally improved over the years, by improved annual fuel utilization efficiency (AFUE) at the burner, enhanced code requirements on duct sealing and insulation, and overall installation practices.  Here are some situations where conventional systems seem to fit best:

  • In older homes that were constructed prior to Inverter Heat Pump technology becoming a great heating option.
  • Hydronic systems in homes where air conditioning was never really considered a priority.
  • Hydronic systems in homes where radiant floor heating is a priority.
  • Forced air systems where duct work provisions have been made during construction.
  • General new construction where the intended homeowner or builder do not “trust” inverter heat pumps for primary heating.

In my opinion, the reason most homes in New England DO use conventional heat, is a combination of the reasoning above, with a strong emphasis on the last bullet point.  The bottom line is that many locals and trade professionals still just do not trust a heat pump to do the work required to heat a home in the dead of winter.

The Alternative
Mainly in the last five years, there has been a significant shift in the mindset of forward-thinking HVAC circles, that Inverter Heat Pump solutions are an excellent solution for both new homes as well as retrofits.  If you align the bullets below with those above, there is a great counterargument for each of those points above.

  • Inverter Heat Pump (IHP) technology IS now a great heating option, and can easily be retrofitted into homes that currently have conventional systems.
  • With heat pumps in general, air conditioning is an automatic benefit with installation, as any heat pump will provide cooling to the space during summer.
  • In general, small areas such as master bathrooms can utilize an efficient electric heat mat beneath tiling to satisfy those looking for warm toes.
  • Although some Mitsubishi Electric systems DO use duct work, many of them are ductless, thus freeing up floor space, basement space, and reducing the need for chases or sofetting throughout a newly constructed home.
  • Refer back to point one – These systems have now been proven, to be efficient in our Seacoast climate, and well North of here.

Resistance Heat vs. Heat Pump

It is a common misconception that any electric heat is inefficient…This is definitely NOT the case when utilizing a heat pump in your home or business. This post aims to spread a basic understanding of the differences between resistance heat and heat pumps.

One of the most frequent questions we are asked during the sales consultation process is if Mitsubishi systems are powered only with electricity (which they are) and how are they able to be so efficient if typically electric heat is thought to be so inefficient. Really this all starts because people tend to think of electric heat as the baseboard heaters installed at floor level that are often found in seasonal New England beach homes and cottages. These heaters are “resistance heaters” and they produce resistance baseboard heat and yes they actually are very inefficient. We have head stories where a baseboard heater has been left running and the homeowner ends up paying exorbitant heating bills. We find that because of the inefficiencies related to electric baseboard heating, people also expect that anything involving electricity for heating will in turn be just as inefficient. What people don’t realize is that a heat pump does not work at all in the same way as these inefficient baseboard resistance heaters.

Baseboards Create Heat, Heat Pumps Move Heat

With baseboard heat you are using amperage and resistance in the wire within the baseboard to generate heat out of thin air. All that amperage is very expensive and will make an electric meter spin round and round leading to high electric bills. The difference with a Mitsubishi system or any heat pump is that heat isn’t “created” as much as it is “moved” from outside to inside. It is a little bit difficult to understand, bit there is still heat in the air even when it is 0 degrees Fahrenheit outside. A heat pump uses refrigerant to steal this heat and move it through the refrigerant line indoors. So the main difference is that a baseboard heater using electric resistance creates heat, while a Mitsubishi heat pump moves heat. It is much more efficient to move heat than it is to create it from nothing.

We hope this helps to clear it up for everyone why Mitsubishi heat pumps and heat pumps in general are able to be so much more efficient than a standard resistance baseboard heater. Have more questions? Contact us today for a free consultation.
