"Tom and his team were wonderful to work with. They not only explained every step of the way to me, but they worked with me, and got me the best system for my home at an affordable price. The installation was seamless, and the crew cleaned up everything afterwards. I cannot say enough great things about Papa T’S Heating and Air from the first call to the end of the install and beyond. They were phenomenal!"

"The installers were incredibly courteous, clean, and very professional. They answered all my questions and showed me everything they were doing. The installation was done quickly and on schedule. The H/VAC system works beautifully!!!! I have already noticed a significant drop in my electricity bills. I have since hired Airco to not only perform further electrical work, but to also do some major plumbing work involving complete replacement of old iron pipes. Again, the work was professional, on schedule, and completely solved the problem. I plan to continue to hire Airco to do any electrical/plumbing work needed in the future."

Mr. Jim Ferrell contacted me and we set up a day and time for the work.  He sent me and email to inform me of what I needed to do to get the computer ready for the service.  Jim called me and I provided the info that he needed to remotely do the service.  He cleaned up my computer and tuned it up.  It works much better than it did before.  Mr. Ferrell was easy to work with and was very professional.  If I ever need anymore computer work done, I will contact him first and gladly recommend him to friends

"The estimate indicated that the installation would require a separate circuit with the cost for this being more than I felt it was worth so I did not have the electrician install the fixture.  However, True Tech did allow me to use my deal on another job that they worked on.  I use them for my electrical, plumbing and HVAC work and find them professional and caring.

Install Boiler FAQs, answered by experts

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.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

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.

Many HVAC companies offer free quotes and free estimates for repairs and new HVAC systems. Others offer low-cost quotes or apply the cost of the estimates or diagnostics to your final bill if you hire them. Be aware that some companies advertise free HVAC quotes and recoup the costs by charging more for their services. Free HVAC quotes are never truly free—they cost the company time and effort—so be a good customer. Also understand that you may end up paying for free quotes in another way if you don’t hire a reputable company.
