Rob Lathrop and his team at Yankee Oil installed some Mitsubishi Mini Splits at my home on August 11th. I'm so pleased with the service I received. They did an amazing job from start to finish. His team was professional and very friendly. Afterward I received instructions on how to operate the new AC/Heating system. Rob took the time to answer all my questions and explain how everything works.Now I have a super efficient top of the line system in my home. I highly recommend Yankee Oil for not only oil service and support but also installation of the Mitsubishi Mini Splits. My home is now cool and comfortable and I'm saving money on utility costs! This winter I look forward to a savings on my oil bill as well.

I've been a 22 year customer of Yankee Oil for heating oil and burner service and they were always reliable, friendly and knowledgable. Two weeks ago our boiler cracked a casting and started to leak. I called Yankee Oil and Rob, the service manager came over to assess the situation and make recommendations on a new boiler. Yesterday Rob and four members of his tech crew came in to remove the old boiler, indirect water heater, etc. and installed all new equipment...boiler, indirect domestic hot water heater, controls, burner, expansion tank and vents. They showed up on time and were in and out in six hours. Everything is plumb, level and tidy. The crew cleaned up everything, soaked up all the water on the floor and swept it clean. I recommend them highly.

Yankee just installed a new boiler and hot water tank, and we could not be happier. Their prices were reasonable and the quality of the installation is top notch. Only ball valves, and lots of them to isolate any potential trouble area. Individual high efficiency circulator pumps for each zone, instead of zone valves that don't regulate flow well. Wiring and plumbing is neat and well organized, the system was made as compact as possible to free up space. They take care of any energize CT refunds available. Their techs are well trained, and have the best equipment for tuning and checking efficiency. They take care of the permits, and the replacement went fast, and they left everything very clean.Above and beyond, these guys earned every star!

HVAC Frequently Asked Questions (FAQ)

If your HVAC system stops working or exhibits signs of malfunction, such as strange noises, reduced airflow, or inconsistent temperatures, it's essential to contact an HVAC professional promptly. Many HVAC companies offer emergency repair services to address urgent issues like no heating or cooling, gas leaks, or malfunctioning components. Attempting DIY repairs can be dangerous and may cause further damage, so it's best to leave repairs to trained professionals.

Regular HVAC maintenance is key to keeping your system running smoothly and efficiently. It's recommended to schedule maintenance at least once a year, ideally before the start of the heating or cooling season. During maintenance, a technician will inspect and clean components, lubricate moving parts, check refrigerant levels, test controls, and perform any necessary adjustments or repairs. This proactive approach can help prevent breakdowns, improve energy efficiency, and prolong the lifespan of your system.

Several signs indicate that your HVAC system may need repair or maintenance, including unusual noises such as banging or grinding, uneven heating or cooling throughout your space, foul odors coming from vents, frequent cycling on and off, increased energy bills, and poor indoor air quality. If you notice any of these signs, it's important to schedule a professional inspection to diagnose and address the underlying issues promptly.

Many HVAC companies offer preventative maintenance plans or service agreements to help customers keep their systems in top condition year-round. These plans typically include scheduled maintenance visits, priority service for emergencies, discounts on repairs or parts, and peace of mind knowing that your HVAC system is being cared for by professionals. Signing up for a maintenance plan can save you time, money, and hassle in the long run while ensuring the comfort and efficiency of your home or business.
