"Profesional, efficient, responsive, and knowledgeable.  Even fixed a few items for me that were not part of the scope of work as well as giving me some tips for bringing my hot water heater up to code.  Would not hesitate to use again."

Nathan Rooen

"I have nothing but great things to say about To the T! Our water heater went out and in a matter of hours they had a new one on its way - I was amazed how quickly they came and replaced it. The price was great too - top notch quality!

Frequently Asked Questions

Do You Install Furnaces?

Yes, we do! We can help you find the best heating system for your needs and install it.

How Much Does It Cost For an HVAC Maintenance Plan?

HVAC Maintenance Plans vary depending upon the home's heating & air system. Call us for a free quote. A maintenance plan will ensure your HVAC system is always properly serviced and is ready for whatever cold or heat that Longmont, Colorado throws your way.

How Often Should I have My HVAC System Serviced?

You should have your HVAC system checked at least once a year. Having your system checked once a year lets us see issues with your HVAC system before they become a bigger and more expensive issue. A great way to have this happen is to have an HVAC Maintenance Plan with To the T Plumbing and Heating. Catch the little things before they become big problems.

How Often Should I Replace My HVAC System?

According to the Department of Energy, an HVAC system should be replaced every 10 to 15 years. Why? After about 10 years internal parts of your HVAC system begin to deteriorate. However, this can differ depending upon maintenance, type of HVAC system installed, and regular upkeep of other materials, such as your air filter.

How Often Should I Replace My Air Filter?

Typically, you'll want to replace your furnace's air filter every 90 days or so but this can vary depending on the type of air filter you use and how often you run your system. Replacing your filters regularly leads to cleaner air quality and increases the longevity of your furnace. Furnaces need clean air filters so they don't overwork due to the dust and other pollutants that pack up on the filter. When purchasing an annual HVAC Maintenance Plan with us, we'll inspect your air filter and will let you know when it should be replaced.
