"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!"

"Dillon was a great guy and worked fast and efficient. My house is 50 plus years old and the duct work had never been cleaned. Post the work, the house even smelled better. I am in the middle of a complete remodel and living in the house. I had all 11 vent grilles removed -(saved Dillon a pile of time not having to remove and re-install) and I would have thought a discount would have been in order."

"Took a few weeks to get the appointment scheduled. They were a few mins. late showing up, but called to let me know, which is much appreciated. Work was completed in a timely manner. I was not there to witness the work, but my husband was and said they were professional and thorough. Pricing seemed to be very negotiable. I paid $175 to have 10 ducts and one main done, but then saw an ad in the QC Times for about half that price the next week. Oh well. They also offered the duct sanitizer which I declined."

"It was physical. The workers were really nice along with the owner of the company. The price was fair. It was not a bargain but it was not absorbent either. They are reliable."

Heating and Air Conditioning questions, answered by experts

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.

There are many recognizable symptoms of AC compressor failure. They include loud banging noises, hot air being continually circulated in your home despite running the AC at full blast, uneven airflow and cooling, and electrical issues like constant surges due to the compressor working overtime. While some of these symptoms, like uneven cooling, can have other root causes, they are common indicators of compressor problems.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.

Yes, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.
