From Our Website

We remain available for service 24/7/365. Out of respect to and concern for the well-being of our customers and employees, please know that we are doing all we can to be as safe as possible. This includes: wearing masks, washing hands, sanitizing, not shaking hands, wearing gloves and maintaining safe distances from others. We ask the same of you while we are in your home or you are visiting our office. We will get through this situation together with continued focus and attention to healthy behavior from everyone.

New air conditioners are about 60% more efficient than their 15-year-old counterparts. Better efficiency translates into lower utility bills which can partially offset replacement costs. Also consider that air conditioners made after 2010 use state-of-the-art environmentally friendly refrigerants that minimize damage to the ozone layer - a benefit for all of us who care about our planet. Plus, Murphy's Law of Air Conditioner Breakdowns says that if you have a dicey air conditioner, it will break down when the temperature hits 94 degrees and you have out-of-town guests arriving in an hour.

Due to higher demand replacing HVAC replacement equipment, we are currently only doing DRYER VENT cleanings. Please do call us for recommendations for another locally owned/operated company who can handle your duct cleaning. Tell-tale signs of dryer vent obstruction: laundry takes an unusually long time to dry and you can sense humidity in your laundry room. These signs are annoying, but they warn of a more serious problem. Dryer lint is highly flammable and can be a fire hazard. If you notice these signs, it is time to have the vent cleaned.

We heartily applaud the Green Building movement's focus on environmental sustainability and energy efficiency. However, weather-tight, energy efficient construction can solve one problem while creating another problem: inadequate ventilation. High levels of indoor air contaminants - including carbon dioxide, cleaning chemicals, cooking fumes, and noxious chemicals produced by off-gassing of carpets and upholstery. Often, the most obvious warning sign is constant winter moisture condensation on the interior side of window panes.

If your current furnace or boiler is 15 years old or older, it's approaching the end of its lifespan and may become less reliable. It's time to consider a new furnace or boiler if yours requires multiple repairs, or if a major component fails. Replacement can be more cost effective than a series of expensive and inconvenient repairs. Old furnaces and boilers tend to call it quits during periods of extreme sub-zero cold and heavy usage, just when you need a warm house the most. If your furnace or boiler is starting to show its age, we can provide the information you need to make a good decision before you have an emergency.

A BETHKE service technician is on call 24/7. From 7:00 a.m. to 5:00 p.m. Monday through Friday, your call will be answered by our helpful office staff. Outside these hours, you will reach one of the friendly people at our answering service who will page the on-call repair expert for you. The on-call technician will return your call promptly. We charge a flat diagnostic fee, which is the fee you pay for a trained and experienced service technician to travel to your home and spend whatever time it takes to diagnose the problem with your heating or cooling equipment.
