Heat Pumps

What is a Heat Pump & How Does It Work?

A heat pump is an energy-efficient alternative to traditional heating and cooling systems. Unlike furnaces that generate heat, heat pumps transfer heat from one place to another, making them highly efficient for year-round comfort. In the winter, they extract heat from the outdoor air (even in cold temperatures) and bring it inside. In the summer, they work in reverse, removing heat from your home to keep it cool.

Benefits of Installing a Heat Pump

1. Energy Efficiency

Heat pumps use less energy compared to traditional HVAC systems, reducing your monthly utility bills.

2. Year-Round Comfort

Unlike furnaces or air conditioners that only heat or cool, heat pumps provide both heating and cooling in a single system.

3. Environmentally Friendly

Since heat pumps rely on electricity rather than fossil fuels, they produce fewer carbon emissions and are a greener choice for home heating.

4. Improved Indoor Air Quality

Heat pumps help regulate humidity levels and filter out airborne contaminants, ensuring cleaner, healthier air in your home.

5. Quiet Operation

Modern heat pumps are designed to operate quieter than traditional heating and cooling systems, providing a more peaceful indoor environment.

Types of Heat Pumps We Install

1. Air-Source Heat Pumps

The most common type, air-source heat pumps transfer heat between your home and the outdoor air, providing efficient heating and cooling for moderate climates.

2. Ground-Source (Geothermal) Heat Pumps

These systems extract heat from the ground rather than the air, offering exceptional efficiency and long-term savings.

3. Ductless Mini-Split Heat Pumps

Perfect for homes without ductwork, mini-split heat pumps offer zoned heating and cooling, allowing you to control the temperature in individual rooms.

How Heat Pumps Compare to Traditional Heating Systems

Heat Pump vs. Furnace

Energy Use: Heat pumps use electricity rather than burning fuel, making them more efficient in mild climates.
Installation Cost: While heat pumps can have higher upfront costs, they often save money in the long run due to lower energy bills.
Lifespan: A well-maintained heat pump can last 15-20 years, comparable to high-quality furnaces.

Heat Pump vs. Air Conditioner

Functionality: A heat pump provides both heating and cooling, while an air conditioner only cools.
Efficiency: Heat pumps are often more energy-efficient, leading to lower operating costs.

Signs You Need a Heat Pump Replacement or Repair

If your heat pump is over 15 years old or showing these signs, it may be time for service:

Reduced Heating or Cooling Performance – Struggling to maintain a consistent temperature
Higher Energy Bills – Increased costs may indicate inefficiency
Unusual Noises – Grinding, rattling, or squealing sounds
Frequent Cycling – The system turns on and off too often
Ice Buildup on Coils – This could signal airflow or refrigerant issues

Heat Pump Maintenance: Keeping Your System in Top Shape

Regular maintenance is essential to keeping your heat pump running smoothly. At Dor-Mar HVAC, we recommend scheduling a professional tune-up twice a year—once before winter and once before summer. Our maintenance service includes:

Inspecting and cleaning coils to improve efficiency
Checking refrigerant levels to ensure proper heat transfer
Lubricating moving parts to reduce wear and tear
Testing the thermostat for accurate temperature control
Ensuring proper airflow to optimize performance

By keeping up with regular maintenance, you can extend the life of your heat pump and prevent costly breakdowns.

Choosing the Right Heat Pump for Your Home

When selecting a heat pump, several factors should be considered:

Home Size: The capacity of your heat pump should match the square footage of your home.
Climate: Heat pumps work best in moderate climates but can be paired with auxiliary heating for extreme cold.
Energy Efficiency Ratings: Look for SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings to find an efficient model.
Budget & Financing: While heat pumps have a higher upfront cost, financing options can make installation more affordable.

Make sure prior to the job you discuss price, process and have it in writing. Our hot water tank needed a new valve which was covered under warranty. Our service maintence package with Dor Mar covered the first hour of labor for the repair. They sent me a bill for the hour labor it took them but I was told it was covered. Very discouraged by this and will be cautious with the next repair. Not good practice especially to a customer who bought the hot water tank through Dor Mar.

Response from the ownerUnfortunely we are at the mercy of the manufacturer when it comes to what is covered under warranty, we are sorry that it was not discussed prior to your repair call that you would owe the labor to put the part in, standard protocall includes a phone call from our parts department to discuss costs before hand. Our records indicate you had discussed the price for the parts call before excepting the estimate for the work. Your labor for the Daignostic call was covered under your Service Contract. We appologize for any misunderstanding and hope you continue with Dor-Mar!

Have been a Dor Mar customer for years. In this instance Calob came out to conduct my Spring AC inspection. The unit had a loud vibration. Calob located the issue quickly and silenced the vibration. Conducted the inspection quickly and pronounced me good to go for the AC season. Will continue to utilize their services. Top notch.

Dor Mar hires great prospects who provide excellent service. My tech, Preston, came and knocked the job out of the park — I’ve had 3 different companies come out and inspect my heat pump several times but we got no where. Wasted money and wasted time.Not only did Preston diagnose the problem on the first visit, he explained everything well enough for me to understand what needed to be done, ordered the parts and had my AC running the next week — Very satisfied! 10/10

Response from the ownerWe truly appreciate you leaving a thoughtful review for our technician Elijah. Thank you for taking the time out of your day to provide such wonderful feedback!

The Dor-Mar team services our heating, air-conditioning, plumbing and drains, and now is helping us with radon mitigation. One common thread in dealing with all of the technicians is they are honest, trust-worthy and professional. Greg B. has been helping us with our radon system and his expertise is greatly appreciated. We are sorry the rating system only goes to 5 - because they truly deserve a higher score.

Dor Mar sent out a employee to drain my hot water heater as part of a maintenance program that I paid for. That employee spent most of the time walking around the inside of my house (my hot water tank is in the basement with an outside access only) taking pictures of all of my plumbing. He did not ask to do this he just started taking pictures saying he was supposed to. He opened my cabinet under my sink and wanted to know why I had a bucket there. (it was to carry cleaning supplies in when cleaning around the house)Then he told me that there was a problem with my tank since he emptied it and it was leaking. I asked him how much it would cost to fix it and he immediately said $2700.00. I told him just to turn the water off to the tank and to just leave. He had placed a bucket under where it was leaking, and he said I won't have hot water. If he turned it off. He then tightens the screw a little more and then it quit leaking.Another problem I had was I told him he could park beside the house (I showed him where) but for some reason he just wanted to walk through the front door and through the house and then out the back door. He did this about 3-4 times.Finally, when he was done, I opened the gate so that he wouldn't walk through my house again and he went straight to the front door saying he was so sorry, but he had lost all of the pictures that he took and had to come in to retake them all again. At this point I was ready to call the sheriff to escort him off the property. I did let him take the pictures and finally he was off.He was polite when talking to me I have no issues there, but all the other stuff was unnecessary... He was there to drain my hot water tank not to do a photo shoot. I will try to come to the office on Monday I am still extremely upset about this. IT IS NOT THE WAY TO DO BUSINESS!

Response from the ownerFrom your description of what the technician did while in your home perfectly describes our Plumbing maintenance Juanita. The plumbing maintenance includes a check on the entire plumbing of the home and the flushing of your hot water tank, we do apologize if that was not properly explained to you when your service was booked. It is also unfortunate the tech couldn't follow the directions you offered to not have to walk through the home and we apologize for that, over all we hope this gives you some ese on what was done by the tech as he was just doing his job.

Angela Seymour

★★★★☆

The service was great. But they don't honor their service windows. My service windows was 12-4 and I get a message at 9:40 that the tech was on the way. I had to rearrange my schedule to fit in the cleaning. Luckily I was close by and could make it to the house in time.

Response from the ownerWe apologize there was an issue with your scheduling, we always try our best to make our time frames, in the future wed be more than happy to have the Tech wait for the scheduled time frame had we known it was an issue for you to make the appointment earlier.

Thank you Dor Mar team with the help today. They quickly repaired a leak. Great communication with scheduling and provided an estimate before starting the job. They have done so much great work at our house. They installed our furnace several years ago, a new water heater and softner this summer. They also have done several repairs of leaky water lines. I cannot say enough good things about them.

Beyond amazing service and customer support. Employee Anthony P. was truly a blessing and went to bat for me against my home warranty company and got my full service approved!

Next plumping issue I experience I’ll go straight to Dor Mar, they are well worth the price from admiration and care alone!
