"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!"

"This was 100% worth hiring this company! I recently purchased a home that previously had a heavy in home nicotine smoker. I wanted the start fresh and clean the ducts and they made hiring and completing the service so worth it. They were extremely responsive and very reasonable in pricing. I would recommend them to anyone needing duct work cleaning."

"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."

"Very good. This was our first time having this done so we didn't know what questions to ask to get a complete estimate. Because of this they added extra services to ensure we would be happy with their work. Very polite and clean. Would definitely hire them again."

"Dillon and George were efficient, friendly, fast, fun, and really know what they're doing. Dillon explained the work details, answered our questions, and was upfront with costs, which we felt were reasonable. It was amazing what they cleaned out of our duct work (even an old dead mouse...ick!). We plan to use Preferred Home Improvements again in the future...thanks guys!"

Heating and Air Conditioning questions, 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%.

HVAC companies may charge an hourly rate or a flat fee. Hourly rates typically range from $100 to $250 per hour, with an average around $175. Some contractors charge a flat fee for specific services, such as an inspection, which can cost between $150 and $500. The total cost of an HVAC service is influenced by several factors, including: the urgency of the service (emergency repairs after hours or on holidays cost more), the time of year, the type, size, and brand of your HVAC system, the specific repair needed, and whether you have a service contract.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.
