"Steve and his assistant tackled the installation of a WIFI contolled thermostat in my 120 year old house, in Ouray Colorado Tracing and replacing the thermostat wires and then hard wiring a 24 V rheostat in the wall adjacent to a 110V power source was an ingenious undertaking.....All turned out Perfect. And they left no messes for me to deal with.... I would strongly recommend this company for their expertise and quality of work performed. Steve also replaced old outdated interior sewer lines in basement same house 3 years ago, and did an outstanding replacement"

"Seriously wonderful company! Everyone does a fantastic job and always goes above and beyond to make sure things are done right and efficiently. We had an entire new furnace and AC system installed and did vent sealant and MAN the difference in our home and utilities speak for themselves. This company does great at spring and fall tune ups and actually go through the entire system instead of just cleaning the outdoor unit. Whenever we've needed a response for something they're quick to get us scheduled and done. Absolutely would recommend to everyone!"

"Jim is local.  It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job.  He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer,  Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

"Recently I had an issue with a hot water heater in one of my rentals. I was disappointed to learn the cost of a water heater at the local hardware store. I called A plus Plumbing and was pleasantly surprised to find out they could squeeze me into the next day's schedule and the cost was only a few dollars more than what I could purchase a new water heater for! After arriving they quickly resolved my hot water issue and tackled another problem with my toilet. Being able to take a hot shower and flush a toilet correctly are such privileges. I usually do my own plumbing, but after this experience I will be calling this local plumber first. Thank you for the great and timely service. Update - since replacing the water heater, I have called A plus Plumbing to set a new trailer (water,sewer,gas) and had them repair a main water leak at another unit with the same promptness and professionalism. They are an affordable 5 star company!"

Install Boiler FAQs, answered by experts

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.
