"I hired All Temp to replace my AC and furnace in my condo. Overall, they did a great job. The initial inspection and quote walk through went very well and they answered every question I had. The installation went equally as well. The crew did great work and finished the project in a timely manner. Would definitely recommend them and use them again in the future."

"Phil came out to provide a free estimate for a new boiler. Appointment was scheduled for the same week and Phil called to move up the appointment due to a cancellation. He was very thorough, asked questions and answered all of mine. Would definitely recommend.

Customers say: True professional

"When the A/C in a townhouse we own started failing (about 20yrs old), we searched for companies that could replace it . The first one was quite responsive, came out and did an assessment and gave us a quote to replace the HVAC system. Their price quote almost knocked us over. Looking for another alternative, we contacted MMDS and sent them pictures of the current set-up. Michael gave us a quote estimate over the phone that was thousands!! less than the original quote for the same equipment. We approved MMDS quote on a Tuesday, got the permit approved on Wed, and they installed the system on Friday. The installer was very professional and even fixed an issue with the dryer vent while he was there. The final price was exactly as originally quoted with no add-ons. A company with this kind of service and response really deserves more than 5 stars. We highly recommend!"

Install Boiler FAQs, answered by experts

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

Most installations take 2-5 days, including old system removal and setup.

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.
