"My combo boiler/hot water went out yesterday Moore did a great job and came up with innovative solutions to get it fixed quickly - very pleased as temps are going to below zero and big snow has begun. Also great job on mask-wearing for COVID. I have used Moore Heating, including buying my boiler from them 9 years ago, and very pleased with their professional service!"

"Dillon diagnosed our problems in minutes and after calculating what we needed exactly and us giving the go ahead he sin the job right then and there after getting the parts needed. He actually fixed our ongoing problem that discount mechanical couldn't diagnose after hours and taught us about what needed to be done down the the tiniest detail and how to keep it on the up and up. I'll never call another plumbing & heating company again, these guys are actually honest and they do the job when they say they're going to do it. It's amazing to meet honest people nowadays."

"They have contacted me for a quote but I have not yet heard back from them. I am leaning toward contacting a friend to assist me in building it myself as I am concerned that I will not be getting the custom project that I need. If they surprize me and are able to come back with a quote for the project we need, I will most likely hire them for the job."

Heating and Air Conditioning questions, answered by experts

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

Swamp coolers cost approximately 50 percent less to install than central air conditioners and cost less to run. Operation costs depend on the size of the unit and home, your climate, utility rates in your area, and the system’s efficiency. Swamp coolers use 15 to 35 percent less power than air conditioners.

One of the first signs of mold in an air conditioner is a musty smell. You're likely to notice the smell when the unit runs, from the air coming out of the vents or the unit itself. You may also be able to see mold growing on the unit, such as near the condenser coils or by the fan. In some cases, there may be visible mold by the vents.

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.
