Scheduling Cleaning

We are now scheduling cleanings starting March 15th.

Call us at 207-400-4065 to make an appointment.

We are committed to providing all of our customers with on-going customer service. Our goal is to ensure that your heat pump continues to operate as efficiently as it did when we initially installed it. In order to accomplish this, we ask that you clean the filters in your indoor units on a regular basis, preferably every 30-60 days.

We also recommend that the units be cleaned by one of our highly trained Service Technicians on a biennial basis. A professional and thorough cleaning is an essential step in maintaining your investment and providing you with years of heating and cooling satisfaction.

Our Technicians will, as a minimum, perform the following tasks listed below.

Clean the indoor heat exchanger coil, blower wheel, and the outside condenser coil.
Wash the large and small filters located in the indoor unit.
Flush the condensate line and verify that it is free of obstructions and draining properly.
Insert pan treatment tablets in the drain pan that will assist in keeping the drain from being plugged and help control odor.
Test, measure and record operating temperatures at the indoor unit.
Check and clean condensate pump, if applicable.

We suspend cleanings when temperatures go below freezing.

Prices vary depending on your equipment configuration. We would be happy to provide you with a specific quote prior to scheduling.


When Extreme Cold Strikes, Reliable Performance is Key

From Mitsubishi Electric’s blog:

Last week, the U.S. experienced widespread (and in many places, unprecedented) cold temperatures, as a massive cold front swept the country. The record-breaking winter storm brought extreme cold, snow and ice and left homeowners with power outages, burst water pipes, property damage and strained HVAC systems in its wake.

Performance is Key
Last week’s weather was unexpected, even in places where snowfall and extreme cold are rare, but not unheard of. As homeowners in typically warmer climates cranked their heating systems to combat the cold, many saw their systems struggling to keep up with the sudden demand.

It’s easy to pin this type of weather event as an anomaly, but consider this: two weeks prior to last week’s cold front, all 50 states saw below freezing temperatures over the span of one day. 235 million Americans felt the effects of a polar vortex that brought discomfort to homeowners nationwide, and left many reconsidering their HVAC systems’ cold-climate performance.

The Heat Pump Difference
While we can’t always predict extreme outdoor conditions and temperature drops, we can choose systems that perform effectively in any climate. A high-performing heat pump system is efficient and has the capacity to provide comfort in extreme temperatures.

Not only are today’s heat pump systems more energy efficient than traditional, fossil-fuel burning systems, they also perform just as well, if not better! In fact, Mitsubishi Electric units equipped with advanced Hyper-Heating INVERTER® (H2i®) compressor technology perform at 100 percent of rated capacity in outdoor ambient temperatures as low as 5° F, with continued performance down to -13° F.

Homeowners in typically warmer climates may not necessarily need to run out and invest in a hyper-heating system, but it’s important to prepare for extremes, no matter your latitude. Don’t get left out in the cold. Contact us today to schedule an appointment with a Designer.


New Product Spotlight: Introducing The Deluxe Wall Mount FS Model


The patented Mitsubishi Electric Dual Barrier Coating prevents dust and dirt from accumulating on the indoor unit – keeping it cleaner year-round.


The coating is applied to the heat exchanger, vanes and ducts, and to the blower wheel of the indoor unit, which means reduced labor intensive maintenance.

Collects 1/10th of the dirt compared to non-coated components after 10 years of no cleaning maintenance.

Dual Barrier Coating on the heat exchanger, air ducts, vanes and blower wheel helps keep key internal heat pump components clean and working efficiently.


HSPF > 12.5
EER > 12.5
COP AT 5°F > 2.0

Mitsubishi Electric’s Hyper-Heating INVERTER® Plus systems feature the most advanced heat pump technology for delivering exceptional heating performance – producing 100% heating capacity down to -5°F.


Heat Pump Incentives for Businesses

It’s time to replace the old air conditioning system. Efficiency Maine offers incentives to businesses to add high performance heat pumps for cooling and heating from $500 per single zone to $1,250 for multi zones with 4+ indoor units.

If you are a “Small General Service” (SGS) or “Small Service” (SS) electric customer you may be eligible for $1,600 per single zone system with an HSPF of at least 12.5. (Maximum 3 systems for a total of $4,800.)

Call Royal River Heat Pumps at 207-400-4065 to schedule an appointment to talk to a Designer about your project and find out which incentives may apply.


Beneficial Electrification

According to an article from Green and Healthy Homes Maine, if you use an oil boiler, switching to a heat pump can reduce your carbon emissions by 60%. And since 19% of emissions statewide are generated by home heating, making the switch to heat pumps will also help Maine reach our carbon reduction goals by reducing emissions of carbon dioxide 45% below 1990 levels by 2030, and 80% by 2050.

And you won’t be alone. Homeowners and businesses have installed over 45,000 high-performance heat pumps and 32,000 heat pump water heaters in the past five years!

New Year, New Savings

From the Mitsubishi Electric Blog:

A new year always comes with new resolutions and goals, most often geared toward establishing a healthier body and lifestyle. But what about a healthier budget and environment? The new you for the new year can make smart decisions to save money while also reducing your carbon footprint.

Where Does HVAC Come In?
A heat pump can heat your home without burning fossil fuels and can be up to four times more efficient than a conventional option, according to the Rocky Mountain Institute. Installing a high-efficiency heat-pump system, such as our Zoned Comfort Solutions®, can help homeowners significantly reduce their year-round energy consumption, meaning lower utility bills and more sustainable comfort.

Many local utility companies offer rebates and tax credits to homeowners who install new, high-efficiency systems. These incentives help offset initial costs and contribute to the return on investment homeowners realize with the heat pump system’s energy-efficient operation. Lower utility bills and reduced maintenance requirements lead to long-term savings.

These incentives don’t only apply to heating season, however. Heat pumps also efficiently cool homes in the warmer months, allowing homeowners to enjoy energy savings year-round.

Homeowners currently using or considering installing a Mitsubishi Electric system can find out what local rebates are available to them using our rebate finder tool.
