"Water heater went out on a Sunday. Called Monday morning and TMI had an opening. Tom arrived at my home on time, assessed the problem, gave a quote, and then completed the job by replacing the water heater. Tom's work was top notch and completed in a timely manner! I would use TMI again without hesitation!"

"Chad and his team were very friendly yet efficient and professional--they even came an hour early due to being ahead of schedule for the day. I am currently working from home and did not feel disrupted at all while they were cleaning my HVAC system!"

"They fixed my breaker and installed LED lighting, fire detectors in 3 bedrooms in a 6 hour period. Very professional and they cleaned up perfectly afterwards. They could have rushed through but approached me to ask if I wanted dimmer switches and what color. Great work, old school quality customer service."

Heating and Air Conditioning FAQs, answered by experts

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

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.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.
