"Called the company on a Sunday. They arrived on Monday to give me the bad
news I had expected.  My 15 year ole A/C unit had finally died.   Later that day
I received an estimate which I accepted.  The new unit was installed on Thursday
of the same week.
 
The Monday they arrived it was very hot (when else do A/C's die). They
offered and I accepted a portable A/C loaner.  Fast response.  Professional
service. Friendly and capable people.

"Jim Farrell and North Alabama Technical Services rebuilt my computer and provided me with everything I expected and so much more.  He provided the various options in equipment, including specs and pricing, answered all our questions and helped us make the best decision for our purchases.  The computer was completed in a few days, far less than expected, the installation included clear directions for use.  The package also included a good warranty for the equipment.  I was extremely pleased with his service and would not hesitate to recommend his company to anyone with computer service needs."

"Amazing technical expertise and physical strength displayed by Mr. Hall who got the water heater to second floor by himself and safely installed my brand new unit. He's also maintained my AC for the last 7 years and recently replaced my thermostat. He is also knowledgeable and able to make electrical repairs and wiring. He is also an honest person who will advise you accordingly."

"I recently installed a Bose speaker system and the connections were a rats nest of wires and it needed to be balanced. Seth came and rewired the system and balanced the system, including the surround sound speakers in the ceiling. I had two extra Bose speakers that I wanted to use in my bedroom, so Seth brought a used Denon receiver and also provided a 15 foot HDMI cable that we needed for the set up. Seth is great to work with and he completed whole setup in the two hour time frame. I was so lucky to find him on the Angie's List.

"I had debated installing a new system for months. I shopped around; looked at reviews; and decided to go with Major League Contracting Services! The owner, Laz, came from Miami to my home in West Delray to give me an estimate. He said my current unit was too small, and that after 12 years it was time to replace it. We agreed on a price, and set an installation day. They came up on a Saturday and installed my new "York 3.5 ton unit." The air handler is in my attic so it was a tad tricky. After a couple of hours the unit was installed! The installers were very quick, informative, knowledgeable, and polite. Laz even came up and explained the work and even offered to file my registration with York. If you want to work with a local company that goes above and beyond to provide excellent service as well as a competitive then Major League Contracting is the company to use. Call Laz today at 786-344-1846."

"I was in a bit of a bind because my A/C went out and I had a renter coming in 2 days.  They responded to my call immediately. They replaced it immediately. They were there for 8 hours and did not stop until it was done and even bought me dinner.  They followed up after the installation also.  I have had awful experiences with the local A/C companies and this company was not even close and had no problem driving down to Big Coppitt Key. The price of the new A/C was very reasonable too! You must use these guys! Nice clean cut guys too!"

"First, John Page (the design consultant) was there when promised. He was very knowledgeable & took the time to really explain things & their procedures to my Mother & I which made all the difference in making a decision on whom to go with on this journey... I call it a "journey" for these reasons: Out of the 3 other companies we called here in the Keys, not one of the seemed to care enough to spend the time & effort Ellington did, & when we asked about extending our warranties & maintenance etc. nobody had anything remotely close to offer compared to the Ellington "No Worries" program wheras they take care of EVERYTHING & the best part is there are ton of benifits no one else even offered w/no exclusions for 10 plus years. They also offer a 180 day money back guarantee in writing so for those reasons it was an easy choice! The installers were punctual, clean cut & very nice on top of truly demonstrating what was extremely important to us which was true craftsmanship. When making a purchase of this magnitude we know from past experience, it is not necesarily the equipment itself that is so important, it is the installation & setup that is even more important. After all work was done, a quality control audit was performed to assure us the machine was giving us all the efficiency it is supposed to & the ductwork was indeed installed per Johns drawings & sealed air tight as he promised. It passed with flying colors! My Mother & I would certainely recommend Ellington AC to anyone tired of a slick talking salesman that promises the world & then it does not go as planned... Probably the most professional company I have ever dealt with down here, Thank you so much!"

Install Boiler questions, answered by experts

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.
