"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

We give you quality that you can measure, and a finished product that will enhance your home forever. Call us today!

"I hired 3M after considering several other sources for furnace repair. In reviewing other proposals I found excessive charges. 3M called me and when I told him about my problem he asked if he could come and look at it. He arrived as scheduled, was professional, courteous, and thorough. After checking out the furnace he gave me an estimate that was half of my other bids. He obtained the parts, and in working on rhe system found another problem with a transformer. He obtained the part and after completing the repair said that the new parts had cost more than his estimate, but since he had missed the problem initially, he would not charge me for the extra labor. I immediately realized I was dealing with an honest person ... a rarity these days. 3M is now my permanent source for all my HVAC needs. There is no better source available than 3M."

Heating and Air Conditioning questions, answered by experts

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

A blockage in the ductwork may prevent air from flowing through the vent. If some rooms in your home are very hot or cold and another isn't, that can be a sign that a vent is blocked. Another sign of a blockage is a buildup of dirt or dust around the vent. In either case, a duct installer or cleaning service can investigate the issue for you and recommend a course of action.

Fall and spring are the best times of year to purchase an air conditioner, furnace, or other HVAC components. In fact, by shopping during these periods, you could save 10% to 15% on an AC unit. For HVAC professionals, spring and fall are less busy than summer and winter, when extreme temperatures create an urgent demand for heating and cooling.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.
