"He was a little early, which was good, because we had no heat. We thought it might be the fuse, He checked, and it did need to be replaced. The heat still didn't work. A thermostat we installed was the same as the previous model (installed by another company). He took a long time to explain to us that the model we had wasn't the right one for our system and why. He is the first contractor to explain how our system is different. He replaced the thermostat with a different model. The price for the service call with the Angie's list discount was good. We could have purchased a new thermostat for less, but he told us that, and we went ahead since he was here, honest, and so informative. I will definitely call them again."

"Contacted Mr. Bentley and he responded within an a few minutes and came to the house within 2 hours. He inspected and tried several fixes to old furnace but heat exchange was broken from rust accumulated from improper alignment done by previous installer some 2 years ago. Ordered and installed new furnace within 2 days.

"We recently purchased a trailer during last Winter. Being our fist home purchase, we weren't sure of everything we needed to be on the lookout for. The heat pump did a good job of keeping the place warm. But the Summer months were soon on us, and we quickly realized that the AC unit was worthless.
Skip ahead to some 98 degree weather. We had bought a window AC to try to keep cool, but of course, that only helped a small portion of our home. So, we began searching for the best deal in HVAC. A few people gave us quotes. Most of these numbers ranged anywhere from $7,000 to $12,000. We simply couldn't afford that. But while browsing Angie's List, I found Aire Serv offering a great deal. $2500 for a 3-ton unit. I called the company and asked them to come over and decide if the offer would fit our situation. The gentleman that cam over concluded that we needed a 3.5-ton unit, not a 3-ton unit. But, he'd try and get us a deal similar to the one we were inquiring about. Before we knew it, he got someone to authorize a 3.5-ton, 13 SEER unit, with new coil and refrigerant tubes for a price that wasn't too much more than the original deal. We were quite happy, as we wanted to stay out of debt, and this was something we could handle without a loan. It was going to take a week to get the parts in, so the company sent over a couple of portable air conditioners to loan us until the date of install. Skipping ahead a few days to the day of installation, Keith and Gill came by the house nice and early. But they quickly realized that the original quote was not for a heat pump, but just an AC. Keith thought that this was bad for my wife and I, and so he made a few calls. Again, this company nearly blew me out of the water with their business. They offered to get me an AC/Heat Pump, new coil, new refrigerant tubes, new wiring, new thermostat, all for the same price I was originally quoted! Seven hours later, they finished up. I found myself with a new system that works perfectly. The new unit is even a 14 SEER as opposed to the 13 SEER I was originally going to get.
Keith and Gill were both wonderful professionals. They were as courteous and friendly as you can get. They even spruced up the area around the AC outside with some black mulch. If I ever need AC work again, you can bet I'm going to call on Aire Serv!

"Tuck & Howell was responsive and timely in both the initial service call and in the repair work. They were cooperative when we had to delay the work multiple times. The repair work was done for half of the estimate we got from another company and we have had no problems since the repair. The workers were professional and considerate."

"I am extremely glad that I chose Mike's Heating and Air, because Mark (Mike's son) and Andy worked hard to make sure that I was satisfied at every step in the process. Seldom am I overwhelmingly impressed with the level of both quality and value of a service, but Mike's Heating and Air warrants the highest ratings in every category! I now have a high efficiency and very quiet central heating and cooling system in my house after a turn-key, no surprises experience with Mike. I will definitely choose Mike in the future and would recommend him to anyone looking to install a HVAC system."

"SUMMARY: HIGH QUALITY WORK WITH LARGE PRICETAG. Corley plumber arrived on time. Their plumber was polite and offered several options for the repair. The repair was completed correctly and in a timely manner. Work area was cleaned after plumbing work was completed. No problems with the repair since it was completed which was several years ago. In short, I would give them FIVE STARS FOR THE QUALITY OF THEIR WORK. I would hire them again in an EMERGENCY (which is why I hired them for this work; the usual plumbers I use were unavailable), but NOT for non-emergency work. My reason for not wanting to use them for routine work is that their prices were OUTRAGEOUS and I'm not a miser (this is why I removed one star in my rating). The few replacement parts needed would have been nominal cost at a plumbing supply store. That means their labor was $200+/hr for installing compression fit connections which is even easier and quicker than gluing PVC pipes together (no heavy lifting; nothing complicated; easy access to pipes). I've had other plumbing jobs that were too big for me to do. I've found competent plumbers that do a great job (quality like Corley's) for half the price if you are willing to wait a day or two. Lesson: Instant gratification has a high price tag. FYI: They will charge for the cost estimate if you don't have them do the repair."

"The guys worked tirelessly to complete it all. My new heat pump and my sisters' were installed in a very timely manner with a big enough crew to accomplish it all promptly, and so far are working fine. Vaughn and Lucas came to my house from my mom's to install the capacitor on a Friday afternoon when I'm sure they wanted to get done early. Everything is going well at present, though my mother will need a new coil which is in process, but her air is working and the guys said they would return if anything else was needed. They all went above and beyond, helping me to seal up cracks and crevices and to put new screen wire over the vents due to the snakes, which I had started doing myself. They were courteous, respectful and informative, and stayed till the job was done! Thanks to Rhonda and Brandy at the phones, and to Jason and Andy as well!"

Install Boiler FAQs, answered by experts

One of the easiest ways to determine which type of furnace will work best for your home is to contact a professional in your area. Many HVAC companies offer free consultations to help potential customers determine if they need a new system and which type would work best for their home and the community’s climate.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

Installing a boiler requires training, a specific skill set, and extensive experience. Boiler installation can be extremely dangerous, as it involves working with water lines, gas lines, and electricity. For this reason, it’s strongly recommended that you hire a professional to install your boiler. Some states even consider it illegal to work on a boiler without the proper licensing.
