My name is Tom Mull of Mull Bros. Oil, a family-owned heating and cooling company in Wethersfield, Connecticut, where I was born and raised. There’s no doubt that you have seen many changes with the heating oil industry in the past decade or so. While many companies have given up or, out of desperation, have changed their business philosophies, we intend to be here for a long time. As a matter of fact, we’ve been around for over 60 years. My father, Bill Mull, started this company in 1945. At a time when stove-oil was in great demand and #2 fuel was being introduced as a home-heating fuel, Bill decided to get in to the delivery business. In the early 1950’s many oil burners were being installed on coal furnaces. Being mechanically inclined, Bill learned the art of installing and servicing the many styles of oil burners and heating systems.

"Said I was too far for a smaller job, and rather than try take advantage was genuine and honest and provided many good tips. Extremely nice and helpful --- just too bad there not in the neighborhood"

We joined Angie's List in August of 2007 and have earned their Super Service Award every year since 2009 when they started that program. HARP Home Services, LLC is here to take care of all your heating and air conditioning needs. Whether you are looking for a free quote on a new central air conditioning system or are ready to install radiant floor heating or a new boiler for those chilly winter months, we're just a phone call (or e-mail) away. Residential & Commercial.

"We had a furnace installed by Harp on July 8th 2024 after it being diagnosed by their technician as to the reason our ac system was not functioning properly. That’s when our troubles with Harp began. The installation was not done properly, we needed 3 service calls to get the ac to work properly. The installers were sloppy. We cleaned up screws and wire and parts from the old furnace for weeks. When heating season began we noticed that the humidifier installed with the furnace was not operating. We scheduled an appointment to have it repaired and they called the day of the appointment and told us they couldn’t come that day and we had to reschedule, so reluctantly we did. They finally came and repaired it. From what the technician told me it was not wired properly. On January 21st 2025( the coldest night of the year) the furnace stopped working. We called Harp to get someone to come to repair it as we had no heat in below 0º weather I was told the best they could do is to come the next day between 2 and 6 pm. I tried to explain that this was an emergency but to no avail. I called my local oil company and they were at my door within 30 minutes( which I would’ve expected from the company who sold us the furnace) the repaired it quickly and told us that one f the wires on the control panel was not attached properly. It cost me $300. I would NOT recommend Harp to anyone. They are not reliable and do not stand behind their promises of service 24/7. Stay as far away from this company as possible. We are sorry we ever started with them."

"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

Heating and Air Conditioning questions, answered by experts

Is mold in an air conditioner dangerous? Running an air conditioner with mold isn’t safe because it can spread harmful mold spores throughout your home. These spores may cause respiratory problems, allergies, or aggravate asthma in household members and guests. If you suspect there is mold hiding in your air conditioner, it’s best to stop using the HVAC system until the mold is cleaned to avoid health risks and further contamination.

Repairing an AC unit is usually more cost-effective than replacing it, but you should consider the age of your system. Most central AC units last around 15 years, and window units last for between eight and 10 years. If your central AC is more than 10 years old or your window AC is over six years old, you should consider replacing the AC unit rather than repairing it. The repair will fix your issue, but you’ll likely save money in the long run by replacing it rather than repairing it only to replace it a few years later.

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season. 

HVAC replacement doesn't always include ductwork replacement. It depends on the condition of the existing ductwork. You can reuse your ducts if they are in good shape, adequately sized, and meet current standards. However, if the ducts are damaged, poorly designed, or not appropriately sized for the new system, they may need to be replaced or upgraded. HVAC contractors will assess the condition of the ductwork during the replacement process and recommend any necessary modifications or replacements to ensure the new HVAC system operates efficiently and distributes air effectively throughout your home.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
