"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!"

"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."

"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."

Heating and Air Conditioning FAQs, answered by experts

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

Yes. Return air vents are responsible for gathering and pulling in the warmer air. Once they draw it in, your system conditions the air by removing the warmer molecules from it, allowing your air conditioner to dispense the cooler air back into your home. Not only does this create a more comfortable environment for you, but it also keeps your air conditioner from overworking, resulting in lower energy bills. 

No, you should not attempt to replace an AC evaporator coil yourself. This is a complex task that must be performed by a licensed HVAC technician. The process involves handling hazardous and flammable refrigerants, which poses significant safety risks. Attempting a DIY replacement can also cause further damage to your HVAC system and will likely void its warranty. It is necessary to hire a local AC repair professional for this job.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.
